Endaphis Kieff. in the Americas (Dipt.). 



By E. p. Felt, Albany, N. Y. 



The discovery of species referable to this genus from widely 

 separated points in the New World is interesting. Last fall 

 we received from Prof. C. H. T. Townsend, Piura, Peru, two 

 specimens of a small midge reared by him from cotton leaves 

 badly infested with galls containing mites. It is possible that 

 these cotton leaves were also infested by small aphids, though 

 none were observed. The North American species has also 

 been reared. The two forms are characterized below. 



Endaphis abdominalis n. sp. 



Male. Length .25 mm. Antennae nearly as long as the body, thick- 

 ly haired, yellowish ; 14 segments, the first antennal segment greatly 

 produced ventrally and probably dorsally, extending to the middle of 

 the subglobose second antennal segment, the fifth binodose, the two 

 parts of the stem, each with a length over twice its diameter, the en- 

 largements subglobose, each with a thick subbasal whorl of long, stout 

 setae and a well developed subapical circumfilum, the loops of the lat- 

 ter extending to the base of the succeeding enlargement. Palpi quadri- 

 articulate, the first and second segments short, the third with a length 

 about three times its diameter, the fourth as long as the third. Mesono- 

 tum fuscous, the submedian lines yellowish. Scutellum yellowish, 

 postscutellum fuscous. Abdomen light yellow, fuscous basally. Geni- 

 talia yellowish. Wings hyaline, costa pale straw, subcosta uniting 

 therewith at the basal third, the third vein distinctly before the apex, 

 the fifth, indistinct distally, at the distal third, its branch near the basal 

 third. Halteres yellowish transparent. Coxae and femora yellowish ; 

 tibiae fuscous yellowish, the tarsi, especially the distal segments, dark- 

 er. Claws long, slender, evenly curved, simple, the pulvilli narrow, 

 nearly as long as the claws. Genitalia indistinct. 



Female. Length .3 mm. Antennae extending to the second abdom- 

 inal segment, rather thickly haired, fuscous yellowish ; 14 segments, the 

 first antennal segment produced, the dorsal tooth extending to the mid- 

 dle of the subglobose second antennal segment, the fifth subsessile. 

 cylindric, with a length about twice its diameter and thick subbasal and 

 subapical whorls of long, stout setae ; terminal segment broadly oval, 

 with a length about ^ greater than its diameter, broadly rounded api- 

 cally. Palpi probably as in the male. Mesonotum fuscous, the sub- 

 median lines yellowish. Scutellum yellowish, postscutellum fuscous. 

 Abdomen yellowish, the basal three segments a variable fuscous. The
