DREYFUS INSURED MUNICIPAL BOND FUND, INC.
Supplement to Prospectus dated September 1, 1994
The following anticipated changes have occurred:
I. CONSUMMATION OF THE MERGER
The following information supplements and supersedes any contrary
information contained in the Fund's Prospectus.
On this date, the previously announced merger between The Dreyfus
Corporation ("Dreyfus") and a subsidiary of Mellon Bank Corporation
("Mellon") was completed, and as a result, Dreyfus now is a wholly-owned
subsidiary of Mellon Bank, N.A. instead of a publicly-owned corporation.
Mellon is a publicly owned multibank holding company incorporated under
Pennsylvania law in 1971 and registered under the Federal Bank Holding
Company Act of 1956, as amended. Mellon provides a comprehensive range of
financial products and services in domestic and selected international
markets. Mellon is among the twenty-five largest bank holding companies in
the United States based on total assets. Mellon's principal wholly-owned
subsidiaries are Mellon Bank, N.A., Mellon Bank (DE) National Association,
Mellon Bank (MD), The Boston Company, Inc., AFCO Credit Corporation and a
number of companies known as Mellon Financial Services Corporations.
Through its subsidiaries, Mellon managed more than $130 billion
in assets as of July 31, 1994, including approximately $6 billion in mutual
fund assets. As of June 30, 1994, various subsidiaries of Mellon provided
non-investment services, such as custodial or administration services,
for approximately $747 billion in assets, including approximately $97
billion in mutual fund assets.

II. NEW DISTRIBUTOR
The following information supersedes and replaces any contrary
information contained in the Fund's Prospectus and specifically in the
section entitled "How to Buy Fund Shares."
The Fund's distributor is Premier Mutual Fund Services, Inc. (the
"Distributor"), located at One Exchange Place, Boston, Massachusetts 02109.
The Distributor is a wholly-owned subsidiary of Institutional
Administration Services, Inc., a provider of mutual fund administration
services, the parent company of which is Boston Institutional Group, Inc.
Accordingly, references in the Prospectus to Dreyfus Service
Corporation as the Fund's distributor should be substituted with Premier
Mutual Fund Services, Inc.

III. NEW RULE 12b-1 PLAN ARRANGEMENTS IMPLEMENTED
The following information supersedes and replaces the information in
the first and fourth paragraphs contained in the section in the Fund's
Prospectus entitled "Service Plan."
Under the Service Plan, adopted pursuant to Rule 12b-1 under the
Investment Company Act of 1940, the Fund (a) reimburses the Distributor for
payments to certain Service Agents for distributing the Fund's shares and
servicing shareholder accounts ("Servicing") and (b) pays The Dreyfus
Corporation, Dreyfus Service Corporation and any affiliate of either of them
(collectively, "Dreyfus") for advertising and marketing relating to the Fund
and for Servicing, at an aggregate annual rate of .20 of 1% of the value of
the Fund's average daily net assets. Each of the Distributor and Dreyfus
may pay one or more Service Agents a fee in respect of the Fund's shares
owned by shareholders with whom the Service Agent has a Servicing
relationship or for whom the Service Agent is the dealer or holder of
record. Each of the Distributor and Dreyfus determine the amounts, if any,
to be paid to Service Agents under the Service Plan and the basis on which
such payments are made. The fees payable under the Service Plan are payable
without regard to actual expenses incurred.
