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); Westtield, 

 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 

 (Nat. Mus.); Hastings, Fla., July (Dept. Agric); New Orleans, 

 August, (Veazie). A rather large series was captured in June of the 



Fig. 21. — Megarhinus rutilus: Female^nlarg-ed (original), 



present 3^ear 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 Htematamoebaj deserve ea.rly investigation.
