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 onky, 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. O. 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. 
Anopheles ferruginosus. 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, seem to indicate that it can 
be no other than the common and widespread Culex pipiens.
