Catalogue of the Dipterous Insects collected at Singapore and Malacca by
Mr. A. R. WALLACE, with Descriptions of New Species. By FRANCIS WALKER,
Esq., F.L.S.
[Read January 15th, 1856.]
Mr. A. R. Wallace, so well known for his natural-history researches in
the valley of the Amazons, and for the extensive and valuable
collections sent home by him from that portion of South America, has now
turned his attention to the eastern world, and is actively investigating
the natural history of the East Indian Islands, after having spent some
months on the Malay Peninsula. A large portion of Mr. Wallace’s
entomological collections pass into my hands, and being desirous of
making his labours scientifically useful, I have requested Mr. F.
Walker, who has such an intimate knowledge of the insects belonging to
the order _Diptera_, to draw up the following catalogue of the dipterous
insects discovered by Mr. Wallace at Singapore and Malacca. My object in
so doing is to establish a kind of starting-point for tracing hereafter,
when all Mr. Wallace’s collections shall have come to hand, the
geographical distribution of the _Diptera_ in the very interesting
portion of the globe which Mr. Wallace is now investigating with such
indefatigable zeal. Singapore and Malacca, at the extremity of the Malay
Peninsula, are well placed for carrying out the purpose I have in view,
being in connexion northwards through the Burman Empire with the
expanded continent of Asia, and southwards in close approximation with
that archipelago of splendid islands which run in a chain to the north
coast of Australia, and send off a branch northwards through the
Philippine Islands to the coast of China, touching there again the
mainland of Asia. The present catalogue will be followed very shortly by
one detailing the species of _Diptera_ discovered in Borneo, the
materials for which are now nearly all in this country, and other
catalogues will follow until Mr. Wallace’s discoveries in the _Diptera_
are exhausted. That Mr. Wallace will be able to visit all the islands of
the Indian Archipelago is not to be expected; but still, his plan of
exploring those which have been but little examined in a natural-history
point of view, will open up a large amount of information, which, when
combined with the labours of other naturalists who have been working in
the same districts, will give sufficient facts for laying down some laws
on the geographical distribution of the insects belonging to the Order
which forms the subject of the following catalogue. The specimens
collected at Singapore and Malacca were taken during the six months
commencing with May and terminating with October. Where the altitude of
the locality above the level of the sea of any species is known, this
will be found noted in the proper place. Figures will be given to
illustrate new genera or any very remarkable species.

contain “Defects,” such as, but not limited to, incomplete, inaccurate

violates the law of the state applicable to this agreement, the

Defect you cause.
Section 2. Information about the Mission of Project Gutenberg™
Project Gutenberg™ is synonymous with the free distribution of
electronic works in formats readable by the widest variety of
computers including obsolete, old, middle-aged and new computers. It
exists because of the efforts of hundreds of volunteers and donations
from people in all walks of life.
Volunteers and financial support to provide volunteers with the
assistance they need are critical to reaching Project Gutenberg™'s
goals and ensuring that the Project Gutenberg™ collection will
remain freely available for generations to come. In 2001, the Project
Gutenberg Literary Archive Foundation was created to provide a secure
and permanent future for Project Gutenberg™ and future
generations. To learn more about the Project Gutenberg Literary
Archive Foundation and how your efforts and donations can help, see

Section 4. Information about Donations to the Project Gutenberg
Literary Archive Foundation
Project Gutenberg™ depends upon and cannot survive without
widespread public support and donations to carry out its mission of
increasing the number of public domain and licensed works that can be
freely distributed in machine-readable form accessible by the widest
array of equipment including outdated equipment. Many small donations
($1 to $5,000) are particularly important to maintaining tax exempt
status with the IRS.
The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United
States. Compliance requirements are not uniform and it takes a
considerable effort, much paperwork and many fees to meet and keep up
with these requirements. We do not solicit donations in locations
where we have not received written confirmation of compliance. To SEND
DONATIONS or determine the status of compliance for any particular
state visit www.gutenberg.org/donate
While we cannot and do not solicit contributions from states where we
have not met the solicitation requirements, we know of no prohibition
against accepting unsolicited donations from donors in such states who
approach us with offers to donate.
International donations are gratefully accepted, but we cannot make
any statements concerning tax treatment of donations received from
outside the United States. U.S. laws alone swamp our small staff.
Please check the Project Gutenberg web pages for current donation
methods and addresses. Donations are accepted in a number of other
ways including checks, online payments and credit card donations. To
donate, please visit: www.gutenberg.org/donate
Section 5. General Information About Project Gutenberg™ electronic works
Professor Michael S. Hart was the originator of the Project
Gutenberg™ concept of a library of electronic works that could be
freely shared with anyone. For forty years, he produced and
distributed Project Gutenberg™ eBooks with only a loose network of
volunteer support.
Project Gutenberg™ eBooks are often created from several printed
editions, all of which are confirmed as not protected by copyright in
the U.S. unless a copyright notice is included. Thus, we do not
necessarily keep eBooks in compliance with any particular paper
edition.
Most people start at our website which has the main PG search
facility: www.gutenberg.org
This website includes information about Project Gutenberg™,
including how to make donations to the Project Gutenberg Literary
Archive Foundation, how to help produce our new eBooks, and how to
subscribe to our email newsletter to hear about new eBooks.
