LETTER OF TRANSMITTAL.


U. S. DEPARTMENT OF AGRICULTURE,
BUREAU OF ENTOMOLOGY,
lWashington, D. C., Mliarch 15, 1906.
SIR: I have the honor to submit a manuscript entitled "A Classifica-
tion of the Mosquitoes of North and Middle America," prepared by
Mr. D. W. Coquillett, assistant entomologist. The Department so
frequently receives requests for information concerning this subject
from students of entomology, from physicians, and from persons
engaged in sanitary work that the desirability of an explicit publica-
tion on this subject is very obvious. I therefore urge that the manu-
script be published as Technical Series, No. 11, of this Bureau.
Respectfully,
L. 0. HOWARD,
Entomologist and Chief of Bureau.
Hon. JAMES WILSON,
Secretary of Agriculture.

A CLASSIFICATION OF THE MOSQUITOES OF NORTH AND MIDDLE
AMERICA.



INTRODUCTION.

In the following pages all of the subfamilies, genera, and species of
mosquitoes known at the present time to occur in North and Middle
America are briefly described or mentioned. In several instances,
where the species have been founded chiefly upon larval characters,
the adults have not been differentiated in the present work, owing to
the fact that the cast larval skins were turned over to a second person
before they were identified and associated with the bred adults. It
was thought best, however, to publish this work in its present incom-
plete form, so that students might avail themselves of it at the com-
mencement of the mosquito season. The greater number of these
species were founded upon one or two specimens only, so that the range
of variation in the adult stage could not be ascertained by the original
describers.
During the summer of 1905 Dr. L. 0. Howard examined the type
specimens of several of Wiedemann's species in the Natural History
Museum at Vienna, Austria, and with the aid of Dr. Anton Handlirsch,
supplemented by a series of questions by the writer and a collection of
named specimens for comparison, was able to gather some very impor-
tant information in regard to those species which occur in North and
Middle America. The museum collection was found to be in good
condition, and type specimens were indicated by red labels. Follow-
ing is a list of the species examined, with the results obtained by
Doctor Howard:
Anopheles albimanus. The type agreed well with specimens of Anopheles albipes
Theobald.
Anopheles crucians. The writer had correctly identified this species.
Anophelesferruginosus. This was not a new species but simply a change of name for
Culex quinquefasciatus of Say. It is represented in the Vienna museum by four spec-
imens of a Culex; this is in perfect accord with Say's statement that the legs of this
species are much shorter than those of Anopheles punctipennis. His other statement,
namely, that it was an exceedingly numerous and troublesome species on the Miss-
issippi River in May, considered in connection with the characters and measurements
given in the descriptions of both Say and Wiedemann. seen to indicate that it can
be no other than the common and widespread Culex pipiens.

Culex fatigans. The female has simple tarsal claws and the petiole ofithe l::

which the last joint of the hind feet is white, is therefore a different specim,:N
which the writer proposes the name terminalis.
Culex pungens. Three specimens from New Orleans, La. The claws are nWi|
simple, the scales of the wings are wholly brown, and the petiole of the first ad1 |

Cutex trniatua. A badly rubbed specimen of each sex from Savannah, Ga.t 1*S1w
synonymous with Stegomyia calopus Meigen.
Ouer, teniorhynchue. The writer had correctly identified this species. .
The most important changes resulting from this critical examination:
of the types are that the name albimanus replaces ahlbipe, and poe4.I
cats takes precedence over musica, on account of priority in
publication of the original descriptions. i
In the preparation of the present work it has been the constant api!:;
bf the writer to render it intelligible to the average student u
observer by dispensing with the use of all technical terms so far: sii

SUBFAMILIES OF CULICID4E.


In the tables of subfamilies and genera given on subsequent pages
of the present work these groups are arranged in their systematic
sequence, but no attempt of this kind has been made in the tables of
the species. In the lists of species the synonyms are indented.
THE SUBFAMILIES OF THE CULICIDRE.
The family Culicidae was founded by Latreille in the year 1825. He
did not consider it as representing a higher group than a tribe. Only
the long-billed forms were known to him. The short-billed forms
were erected into a distinct group, Corethrinae, equivalent to a family,
by the Italian naturalist Rondani in the year 1856. Schiner, in 1864,
regarded the Corethrine as being only a subfamily of the family
Culicide, and this view has been quite generally adopted by later
writers. In the year 1883 Brauer proposed to include in this family
Sthe genus Dixa, which Schiner, fifteen years previously, had made the
type of a new family, the Dixidae. Dyar, in 1905, proposed to unite
the Dixidae with the Corethrinae, the two groups to form one family,
distinct from the Culicidae.
That these three groups, the Dixidae, Corethrinte, and Culicine, are
closely related to each other admits of no doubt. That the Corethrinae
are much more closely related to the Culicinae than they are to the
Dixidae is also very evident. Thus the larva of the latter is provided
with a pair of fleshy anal prolegs, a structure found in some of the
Chironomidoe, but never present in any of the known larve of the
Corethrinae nor of the Culicinae. In the adults the auxiliary vein in
the Dixide ends at a point opposite the root of the second vein; in the
other two groups it is prolonged nearly one-half of its entire length
beyond the root of the second vein. In the Dixidr the posterior
margin of the wings is provided with hairs only; in the other two
groups it is fringed with scales. Again, in the Dixidae the antennae are
almost bare, and are similar in the two sexes; in the Culicime, with
a single exception, and in the Corethrinae these organs bear many long
hairs, which, with few exceptions, are longer and much more numer-
ous in the male than in the female. It will thus be seen that the
Dixida are sufficiently distinct to he maintained as a separate family.
The radical difference in the structure of the mouth parts in the
adults of the other two groups, added to the equally great difference
in the-food habits of the females, renders highly desirable their sepa-
ration into distinct families, and we can do no better than to follow
the lead of Rondani and consider that the short-billed forms constitute
a family by themselves, the Corethridw. With these forms elimi-
nated, the family Culicidae becomes a very homogeneous group, char-
acterized by long, slender antennae composed of fourteen or fifteen
joints; a greatly elongated, slender proboscis; the presence of scales

on the wing veins; ten veins and subdivisions of veins which reach the
margin of the wings and a vein along the posterior margin; and by..... i
the absence'of a disca] cell and of spurs at the apex of the inner sia
of the tibiae. 4 PIT:
In the family Culicidte as thus restricted Theobald ip the year 1901 '.4
erected the following live subfamilies: Anopheline, Megarhinins, a ,
Culicinme, Aedeomyinve, and Trichoprosoponina. The Agdeomyinm N0
were separated from the Culicinae by the much shorter palpi of ti '.
male. This appeared to be a natural division so long as there were
known only forms wherein the palpi of the male in the one group are [i
at least as long as the proboscis, while in the males of the other group
they are less than one-fifth of this length; but the recent discovery of 74J
forms in which the male palpi are in one case one-third as long and in A
the other nearly one-half as long as the proboscis, greatly weakens the j
supposed importance of this difference in the relative length of the ':
male palpi. Moreover, both as regards the larva and the structure of i
the tarsal claws and shape of the scales in the adults, some of the forms a
with short palpi in the male are much more closely related to species i.;
with long palpi in the male than they are to any of the others of the I
group with short palpi. These two divisions are thus seen to be
unnatural and the two proposed subfamilies, namely, Culicine and 4|
Adeomyine, should therefore be merged into one. :I
In the year 1904 Lahille separated out the genus Uranwtwnia as the
type of a distinct subfamily which he named Uranotanina, giving as i
its principal distinguishing character the great elongation of the peti- :
ole of the first submarginal cell and the consequent shortening of this I
cell; the larva has the four tufts near the middle of the head repre- S
sented by stout spines which are covered with spinules. Lutz, in the
same year, erected four supposed new subfamilies: Hmemagogins,
Aedine, Hyloconopine, and Dendromyine; the first of these belongs
to the Culicinte as above constituted, the second is a mixture of three "
subfamilies having short palpi in both sexes and the posterior end of
the thorax bare, while the Hyloconopinme and DendromyinMe will fall
as synonyms of Trichoprosoponine. ,
Very recently, in the early part of the present year (1906), Miss E. G.
Mitchell erected two additional subfamilies: Psorophorinme and Deino- ,
ceritinaw. The first was founded on tie genus P8orophora, previously -
placed in the Culicina, but which, according to the habits of the larva. i
and the structure of its mouth parts, is much more closely related to *
the Megarhinina. The second subfamily was founded on the genus .
DeinoceTites, which differs radically from all the other members of the -;|
Culicidae, not only in the structure of the mouth parts, particularly ;?|
the mandibles, of the larve, but also in the antennae of both sexes inW
the adults. ,,.

SUBFAMILIES OF OULICIDtE.


The following table exhibits the relationships and differences exist-
ing in the various subfamilies of the family Culicidae at present known
to occur in North and Middle America; the latter term, as employed
by Jordan and Evermann in their admirable work on the fishes of this
region, is intended to include Mexico, Central America, and the West
Indies. There are characters in the eggs and larva' also which sup-
port the differentiation of these subfamilies, but these are not given
here, since the larvae will be considered in another publication of this
Bureau:
