A Systematic Study of the Anthomyiinae of New York 25 



Until recently Hylemyia cilicrura Rond. has been confused with H. 

 fusdceps Zett. According to Stein (1916), however, cilicrura Rond. and 

 fusciceps Zett. are two distinct species.

Hylemyia curvipes is commonly collected near the ground in the gorges 

 of Ithaca and its vicinity, during May and June. The female of the species 

 has entirely eluded constant efforts to capture it.

The infuscation of the femora, palpi, parafacials, cheeks, and frontal 

 vitta varies considerably in the specimens hsted above. The pra may be 

 present or absent. The hypopygium and the ovipositor are exactly alike 

 in Hylemyia depressa and H. testacea.

The writer has a male specimen determined by Stein as Chortophila 

 florilega Zett., which in appearance closely resembles the two male speci- 

 mens mentioned above. All, including Hylemyia angustiventris Mall., 

 agree in the follomng points: the third and fourth abdominal sterna 

 possess a few conspicuous, long bristles, directed ventrad, which are 

 arranged in a series along the lateral margins; the thorax has three faint 

 but distinct narrow vittae; the abdomen possesses a comparatively broad, 

 uniform, dorsocentral vitta ; the arista is minutely but distinctly pubescent ; 

 the face is noticeably concave. In addition, these specimens may be
