JULY 3, 1997

Dear Shareholder:
When Delaware Group first offered the Decatur investment strategy to the public
in 1957, Sputnik had not yet been launched. Alaska and Hawaii were not yet
states. The average worker earned only $2.05 an hour.

        Four decades later, the world is a much freer, more prosperous place.
Still, I believe the Decatur strategy - a consistent, time-tested discipline
based on dividend yield and fundamental value - is as relevant for today's
market environment as it was when I was in college.

        I am pleased to report that Decatur Income Fund marked its 40th
anniversary by outperforming the average of its equity income peers for the six
months ended May 31, 1997. As you'll see on page 3, the Fund's younger sibling,
Decatur Total Return Fund, turned in equally robust results during the period.

I BELIEVE THE DECATUR STRATEGY - A CONSISTENT, TIME-TESTED DISCIPLINE BASED ON
DIVIDEND YIELD AND FUNDAMENTAL VALUE - IS AS RELEVANT FOR TODAY'S MARKET
ENVIRONMENT AS IT WAS WHEN I WAS IN COLLEGE.

        For the past six- and 12-month periods, both Decatur Funds also provided
superior returns relative to the unmanaged S&P BARRA Value Index, which includes
stocks that meet BARRA International's definition of value stocks and accounts
for 50% of the market capitalization of the unmanaged Standard & Poor's 500
Index.

        Since November, stock prices have continued to advance at a remarkable
rate. In just three years, the Dow Jones Industrial Average has more than
doubled to nearly 7900 points, a pace that substantially exceeds the market's
average annual historical returns.

        In fiscal 1997, both Decatur Funds have benefited from the strong
performance of financial, drug and capital goods stocks. This has occurred
against a backdrop of strong U.S. economic growth, a modest increase in interest
rates and, despite the lowest rate of unemployment since 1973, a benign 3%
annual rate of inflation.

        This best of all possible worlds cannot last forever. Any prudent,
long-term investment strategy acknowledges the historical fact that stock
markets move in cycles. Periods of expansion and prosperity can be followed by
uncertain times, when an effective stock selection strategy is especially
valuable.

THE DECATUR FUNDS' PERFORMANCE AS WELL AS THAT OF THE LIPPER EQUITY INCOME FUND

VALUE INDEX ARE UNMANAGED. A DIRECT INVESTMENT IN AN INDEX IS NOT POSSIBLE. PAST
PERFORMANCE DOES NOT GUARANTEE FUTURE RESULTS. PERFORMANCE INFORMATION FOR ALL
CLASSES OF BOTH FUNDS CAN BE FOUND ON PAGES 10 AND 11.

        For 40 years, the Decatur management team has helped investors harvest
opportunity by focusing on established companies with above average dividend
yields - oaks with the potential to yield plenty of acorns. In fact, $1 invested
in Decatur Income Fund at its inception would have grown more than a
hundred-fold as of May 31, 1997, as shown on pages 12 and 13.

        In the pages that follow, your Funds' portfolio manager -John B. Fields
- - says there are still many acorns to be gathered in today's market even though
the average dividend yield of the S&P 500 on November 30 was 1.71%, an historic
low. He describes his positioning of the Funds as well as his outlook for the
balance of 1997.

        We appreciate your confidence in Delaware Group's flagship funds, which
have grown to more than $3 billion in assets, from just over $2 million at the
time of Decatur Income Fund's first semi-annual report.

Sincerely,

                           PORTFOLIO MANAGER'S REVIEW

During the first half of fiscal 1997, America's economy was a powerful
locomotive racing ahead under a full head of steam. The nation's output of goods
and services grew at a robust annual rate of 5.8%. The unemployment rate was
only 4.9%, the lowest level since 1973. Corporate profits in many sectors
exceeded expectations.

        At the helm of this engine was a Federal Reserve Board whose effective
monetary policy controlled inflation and thus prevented growth from becoming a
runaway train. Between November and May, investors in established, large
capitalization companies were rewarded with returns that far exceeded historical
averages.

        It was nonetheless a bumpy ride. When the Federal Reserve Board modestly
raised its target for short-term U.S. interest rates on March 13, the U.S. stock
market suffered its first full-fledged correction in seven years. Bond prices
also temporarily slumped, with yields on 30-year U.S. Treasury securities rising
to 7.18% before settling back down to 6.91% as of May 31.

        Still, it took only a few weeks for the equity market to get back on
track. As of May 31, most unmanaged benchmarks of market performance were near
or at all-time highs. However, as you can see below, the dividend yields on most
of Decatur's top 10 holdings were much higher than that of the S&P 500 Index, an
indicator of our value focus.

FAVORABLE FINDINGS: PHARMACEUTICALS, FINANCIALS AND OFFICE EQUIPMENT Most of the
Decatur Funds' largest holdings as of May 31 were stocks we held at the start of
the 1997 fiscal year. The Funds had strong positions in pharmaceutical,
financial services and capital goods companies, and many stocks in each of these
high-yielding sectors provided superior returns.

        Rather than bet on the direction of interest rates or the U.S. economy,
we select companies with above-average dividend yields that we believe are
well-managed and have capital appreciation potential. Since November, we
concluded that many drug companies and financial firms offered strong earnings
potential based on a combination of new products, cost-cutting programs and
stock buybacks.

IN A STOCK MARKET WITH INCREASING VOLATILITY, IT IS NOT ENOUGH JUST TO FIND
CHEAP COMPANIES WITH ATTRACTIVE DIVIDENDS. WE'RE CONCENTRATING OUR EFFORTS ON
BUSINESSES WE BELIEVE ARE IMPROVING IN WAYS LIKELY TO ATTRACT THE MARKET'S
ATTENTION.

        Another area of opportunity was office products makers such as XEROX
CORP and PITNEY BOWES. In our opinion, these dividend-paying stocks offered an
excellent way for your Funds to participate in business' efforts to increase
office productivity through technology with much less price risk than an
investor would have by buying more expensive, non-dividend paying technology
stocks.
        While we maintained our historic discipline of seeking yields greater
than the S&P 500, we have also been paying more attention to catalysts that
could potentially unlock the value of individual companies. In a stock market
with increasing volatility, it is not enough just to find cheap companies with
attractive dividends. We're concentrating our efforts on businesses we believe
are improving in ways likely to attract the market's attention. In each Fund,
we've reduced the number of holdings by more than 15% so we can focus on the
most promising investment opportunities.

        Although we had many successes since autumn, we had a few
disappointments, too. Chief among them was FRONTIER CORP., a long distance
telephone services provider. While the company's dividend yield was attractive,
its earnings and business prospects did not meet our expectations. We've
retained our position because we believe recent industry activity has increased
prospects for either an internal turnaround or a merger with another telephone
company.

WE INCREASED INCOME POTENTIAL 
Decatur Income Fund seeks to maintain a higher yield than the S&P 500 through a
combination of stock selection and the effective use of a small complement of
high-yield bonds. We increased the Fund's weighting in high-yield bonds from 10%
in November to 14% as of May 31. This strategy worked well as high-yield bonds
outperformed other fixed-income investments as well as some aggressive growth
stocks.

        High-yield bonds add to the Fund's income potential; however, they are
issued by companies whose ability to pay interest and repay principal is not as
strong as companies with "investment-grade" ratings. The strength of the U.S.
economy helped high-yield bonds perform well since autumn.

        Our high-yield bonds are managed by Gerald T. Nichols, a senior Delaware
Group fixed-income portfolio manager. He and his team generally follow a
"quality first" philosophy and focus on bonds rated BB and B, the top two tiers
of high-yield credit ratings.

        Since November, Decatur Income Fund focused primarily on high-yield
bonds rated B to maximize income potential. We increased our bond weighting
because we believe the U.S. economy can remain healthy,

allowing bond issuers to meet their obligations. In our view, the 10% yield
available from many high-yield bonds is an attractive complement to stocks,
especially given the fact that the stock market has come so far so fast during
the past three years. We believe the possibility of a more volatile stock market
in the months ahead has risen, and we see the high-yield market as an effective
way to provide an additional element of diversification to reduce potential
risk.

ONE OF THE BEST WAYS INVESTORS CAN PREPARE THEMSELVES FOR WHAT LIES AROUND THE
BEND IS BY UTILIZING A CONSISTENT, TIME-TESTED INVESTMENT DISCIPLINE.

OUTLOOK

In the 1990s, the U.S. economy has benefited from the Federal Reserve Board's
role as an effective railway engineer. Beginning in 1994, inflation was kept
under control through a consistent application of economic brakes in the form of
modest increases in short-term interest rates. This prudent monetary policy has
helped fuel a period of capital appreciation from stocks that's been as powerful
as any in this century.

        We are pleased to report that while our approach has been less
aggressive than that of some equity mutual funds, both Decatur Funds have fully
participated in the market's rewards of the past three and five years, as shown
on pages 10 and 11.

        At this point, some investors may be wondering: how much steam can be
left in equity investments for the balance of the 20th century? Will changes in
tax policy or a bubble of speculation derail the stock market?

        While any portfolio of stocks is subject to market fluctuations, we
believe one of the best ways investors can prepare themselves for what lies
around the bend is by utilizing a consistent, time-tested investment discipline.
Even as the market has risen, our research has unearthed undervalued companies
with dividend yields of 2% to 4%. In the months ahead, we will seek to find more
undervalued companies with similar total return potential.

A Strategy For All Seasons

A popular song in the 1960s said there was a time for everything - for war and
peace, for love and hate, for taking and giving. When it comes to selecting
stocks for your Funds' portfolios, Decatur's management team believes there is a
time to buy, a time to sell.

        Decatur Income Fund and Decatur Total Return Fund follow a very clear
buy/sell strategy that targets stocks with above-average dividend yields as well
as capital gains potential. To be eligible for purchase or holding by the Funds,
stocks must have a current dividend yield greater than that of the Standard &
Poor's 500 Index and capital appreciation potential.

        Decatur's management is most attracted to stocks whose yield is "high"
relative to the S&P 500 but not necessarily the "highest" yield available. By
exercising this consistent investment discipline, your Funds' management team
can reduce exposure to overvalued stocks and take advantage of market
opportunities as they arise.

        As shown in the chart below, this "high" category of stocks has
historically generated the greatest level of total return by providing
above-average dividend income and the highest degree of capital appreciation.

        When a stock's yield falls below the average of the S&P 500, we view
that as a sign that the stock has become fairly priced and that future
appreciation potential is no longer attractive relative to possible risks. So we
begin to sell our position. Sometimes we sell a stock whose yield is still above
that of the S&P 500 average if we find what seems to be a more attractive
candidate for either Fund or when a company's earnings or business operations
have not met our expectations.

LONG-TERM RETURNS OF DIVIDEND
PAYING STOCKS 1929 TO 1996


              INCOME            CAPITAL          TOTAL

Highest        7.7%              3.3%            11.0%


The Decatur Funds' investment strategy leads the portfolio manager to select
stocks that fall within the "high" yield category. As you can see, these
income-producing stocks have provided the highest annual average total return
since 1929. The top number represents average annual total return.

Our Dividend-Oriented Buy/Sell Discipline at Work:
VALUE IN VANITY: WARNER-LAMBERT CORP.

Look in your bathroom and you'll probably find Warner-Lambert products such as
Listerine mouthwash, Schick razors and Sudafed cold remedies.

        We selected this New Jersey-based consumer goods and pharmaceutical
maker in early 1995 when the company's stock had a yield that was more than
one-and-half times that of the average yield of stocks in the S&P 500 Index.
(yield = dividends/ price).

        At the time, the company's stock was suffering a hangover from
government attempts to regulate drug prices and reform the health care industry.
Analysts were concerned about the company's long-term earnings prospects.

        We saw something more attractive. To us the increase in Warner-Lambert's
dividend yield above the S&P 500 was a signal of value and potential capital
appreciation. After Decatur's management completed a careful fundamental
analysis of the company, we concluded that Warner-Lambert was a well-managed,
diversified, global business. So we began purchasing shares.

        Gradually, the company's prospects improved as it developed and marketed
new drugs to treat high cholesterol, diabetes and prostate cancer.
Warner-Lambert also opened a gum factory to make Chiclets in China.

        This past winter, we sold the two funds' entire position as the
company's share price doubled from our purchase price and its dividend yield
dropped to less than that of the S&P 500 Index.

DELAWARE GROUP
EQUITY FUNDS II, INC. --
NOTES TO FINANCIAL STATEMENTS --
MAY 31, 1997
(UNAUDITED)
- --------------------------------------------------------------------------------
Delaware Group Equity Funds II, Inc. (The "Company") is registered as a
diversified open-end investment company under the Investment Company Act of
1940, as amended. The Company is organized as a Maryland Corporation and offers
four series: the Decatur Income Fund, the Decatur Total Return Fund, the Quantum
Fund and the Blue Chip Fund (the "Funds"). Each series offers four classes of
shares.

The investment objective of the Decatur Income Fund is to achieve the highest
possible current income by investing primarily in common stocks that provide the
potential for income and capital appreciation without undo risk to principal.

The investment objective of the Decatur Total Return Fund is to achieve
long-term growth by investing primarily in common stocks that provide the
potential for income and capital appreciation without undo risk to principal.

1. Significant Accounting Policies
The following accounting policies are in accordance with generally accepted
accounting principles and are consistently followed by the Funds.

Security Valuation - Securities listed on an exchange are valued at the lasted
quoted sales price as of the close of the NYSE on the valuation date. Securities
not traded or securities not listed on an exchange are valued at the mean of the
last quoted bid and asked prices. Long-term debt securities are valued by an
independent pricing service and such prices are believed to reflect the fair
value of such securities. Money market instruments having less than 60 days to
maturity are valued at amortized cost which approximates market value. Other
securities and assets for which market quotations are not readily available are
valued at fair value as determined in good faith by or under the direction of
the Fund's Board of Directors.

Federal Income Taxes - Each Fund intends to continue to qualify as a regulated
investment company and make the requisite distributions to shareholders.
Accordingly, no provision for federal income taxes has been made in the
financial statements. Income and capital gain distributions are determined in
accordance with federal income tax regulations which may differ from generally
accepted accounting principles.

Class Accounting - Investment income, common expenses and realized and
unrealized gain (loss) on investments are allocated to the various classes of
the Funds on the basis of daily net assets of each class. Distribution expenses
relating to a specific class are charged directly to that class.

Repurchase Agreements - Each Fund may invest in a pooled cash account along with
other members of the Delaware Group of Funds. The aggregate daily balance of the
pooled cash account is invested in repurchase agreements secured by obligations
of the U.S. government. The respective collateral is held by the custodian bank
until the maturity of the respective repurchase agreements. Each repurchase
agreement is at least 100% collateralized. However, in the event of default or
bankruptcy by the counterparty to the agreement, realization of the collateral
may be subject to legal proceedings.

Other - Expenses common to all Funds within the Delaware Group of Funds are
allocated amongst the Funds on the basis of average net assets. Security
transactions are recorded on the date the securities are purchased or sold
(trade date). Costs used in calculating realized gains and losses on the sale of
investment securities are those of the specific securities sold. Dividend income
is recorded on the ex-dividend date and interest income is 



<PAGE>

recorded on the accrual basis. Original issue discounts are accreted to interest
income over the lives of the respective securities. The Decatur Income Fund
declares and pays dividends from net investment income on a monthly basis and
capital gains annually. The Decatur Total Return Fund declares and pays
dividends from net investment income on a quarterly basis and capital gains
annually.

Certain Fund expenses are paid through "soft dollar" arrangements with brokers.
The amount of these expenses are less than 0.01% of the Fund's average daily net
assets.

Use of Estimates - The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

2. Investment Management and Other Transactions with Affiliates 
In accordance with the terms of the Investment Management Agreement, the Funds
pay Delaware Management Company, Inc.(DMC) the Investment Manager, an annual fee
which is calculated daily at the following rates less fees paid to the
independent directors; 0.60% on the first $100 million of average daily net
assets, 0.525% on the next $150 million, 0.50% on the next $250 million and
0.475% on the average daily net assets over $500 million for the Decatur Income
Fund, and 0.60% on the first $500 million of average daily net assets of the
Fund, 0.575% on the next $250 million, and 0.55% on the average daily net assets
over $750 million of the Decatur Total Return Fund.

5. Lines of Credit
Committed lines of credit were $68 million for Decatur Income Fund and $26
million for Decatur Total Return Fund. No amount was outstanding at May 31,
1997, or at any time during the fiscal year.

6. Concentrations of Credit Risk
The Decatur Income Fund may invest in high-yield fixed income securities which
carry ratings of BB or lower by S&P and/or Ba or lower by Moody's. Investments
in these higher yielding securities may be accompanied by a greater degree of
credit risk than higher rated securities. Additionally, lower rated securities
may be more susceptible to adverse economic and competitive industry conditions
than investment grade securities.

The Decatur Income Fund may invest up to 15% of its total assets in illiquid
securities which may include securities with contractual restrictions on resale,
securities exempt from registration under Rule 144A of the Securities Act of
1933, as amended, and other securities which may not be readily marketable. The
relative illiquidity of some of these securities may adversely affect the Fund's
ability to dispose of such securities in a timely manner and at a fair price
when it is necessary to liquidate such securities. These securities, if any,
have been denoted in the Statement of Net Assets.
