8 CLASSIFICATION OF MOSQUITOES. 
Culex fatigans. The female has simple tarsal claws and the petiole of the first sub- 
marginal cell is about one-third as long as the cell. 
Culex molestus. This is identical with Psorophora ciliata Fabricius. 
Culex posticatus. The type has the last two joints of the hind feet wholly white; 
Janthinosoma musica Say isasynonym. The Janthinosoma posticata of Theobald, in 
which the last joint of the hind feet is white, is therefore a different species, for 
which the writer proposes the name terminalis. 
Culex pungens. Three specimens from New Orleans, La. The claws are apparently 
simple, the scales of the wings are wholly brown, and the petiole of the first submar- 
ginal cell is from one-sixth to one-fifth as long as the cell. It is evidently identical 
with pipiens. 
Culex teniatus. A badly rubbed specimen of each sex from Savannah, Ga. It is 
synonymous with Stegomyia calopus Meigen. 
Culex teniorhynchus. The writer had correctly identified this species. 
The most important changes resulting from this critical examination 
of the types are that the name a/A/manus replaces albipes, and posti- 
catus takes precedence over musica, on account of priority in the 
publication of the original descriptions. 
In the preparation of the present work it has been the constant aim 
of the writer to render it intelligible to the average student and 
observer by dispensing with the use of all technical terms so far as

this could be done without sacrificing either accuracy or clearness. 
A few terms, however, which could not be avoided, will need an 
explanation; these relate chiefly to the veins and cells of the wings, 
and it is believed that they will be made plain by reference to the 
accompanying illustration (fig. 1). The petiole of a cell is the last 
section of the vein before it forks to form the cell. The segments of 
the abdomen and the joints of the feet and antennz are numbered from 
the point of attachment outwardly; thus, the large bulbous joint of 
-the antenne which is attached to the head is the first joint, the one 
next to it is the second, and so on. The seutellum is the semicircular 
piece at the posterior end of the upper part of the thorax, from which 
it is separated by a transverse suture. The remaining terms will no 
doubt be readily understood by the average reader.
