is very stout. The most striking feature of this insect, however, is 
the curious series of erect close-set hairs or scales on the legs, which 
distinguishes it at once from other mosquitoes. This mosquito is 
widespread in the United States, and we have specimens from Dorches- 
ter, Mass. (Nat. Mus.); Washington, D. C. (Chittenden); Westfield, 
N. J., July 2 (Johnson); Illinois (Nason); Brooklyn Bridge, Ky., June 
23 (Garman); Lincoln, Nebr., July and August (Bruner); Los Angeles, 
Cal. (Coquillett); San Diego, Tex., May 15 (Schwarz); Florida, July

Fie. 21.—Megarhinus rutilus: Female—enlarged (original), 
present year at St. Elmo, Va., by Mr. Pratt. The writer felt certain 
that he would be able to follow out the life history of this species from 
the living material captured by Mr. Pratt. Females were placed alive 
in breeding jars under conditions which had repeatedly been successful 
with Culex and Anopheles, but no eggs were obtained. The breeding 
habits, therefore, may be different from those of the other two genera, 
and the biology of this form is an interesting and important point for 
future investigation. As elsewhere stated, the possible relations 
between Psorophora and the Hematamoebee deserve early investigation,
