Sept., I9II.] Felt: Three New Gall Midges. 191 



Female. — Length 1.5 mm. Antennae extending to the second abdominal 

 segment, sparsely haired, fuscous yellowish, the basal segments yellowish: 16 

 segments, the fifth having a stem about one-third the length of the subcylindric 

 basal enlargement, which latter has a length about twice its diameter, a 

 rather thick subbasal whorl of long, stout set;e and a scattering, subapical 

 band of slender setae ; terminal segment with a length about three times its 

 diameter, narrowly separated from the preceding and tapering to a subacute 

 apex. Claws long, slender, evenly curved, unidentate, the pulvilli rudi- 

 mentary. Ovipositor when extended about one-third the length of the ab- 

 domen, the terminal lobes slender, indistinctly triarticulate, the distal segment 

 with a length about three times the diameter and sparsely setose. 



Type Cecid ?i2\yyh, N. Y. State Museum. 



Several specimens of this midge were reared the latter part of 

 May, 191 1. It is allied to H. clongatus Felt, from which it is sepa- 

 rated by the shorter stems of the antennal segments. 



Lasiopteryx schwarzi, new species. 



Male. — Length i mm. Antenna; nearly as long as the body, thickly 

 haired, dark brown: 12 segments, the fifth with a stem about three-fourths 

 the length of the cylindric basal enlargement, which latter has a length one- 

 half greater than its diameter, a sparse subbasal whorl of rather short setae 

 and a thick subapical band of long, slender setse ; terminal segment somewhat 

 produced, fusiform, with a length about three times its diameter. Palpi : first 

 segment irregularly subquadrate, the second with a length nearly three times 

 its diameter, the third a little longer, more slender, the fourth nearly one- 

 half longer than the third, slender. Mesonotum shining dark brown. Scutel- 

 lum reddish brown, sparsely haired, postscutellum darker. Abdomen mostly 

 dark brown, the distal segments and genitalia more or less yellowish orange. 

 Wings subhyaline, the membrane rather thickly scaled, costa dark brown or 

 black; the third vein unites with costa near the distal ninth; the fifth joins the 

 posterior margin at the distal fifth, its branch near the basal third. Halteres 

 yellowish orange. Coxae, femora and tibiae mostly yellowish orange, the tarsi 

 dark brown. Claws rather long, slender, evenly curved, unidentate, the pul- 

 villi about one-half the length of the claws. Genitalia ; basal clasp segment 

 rather long, moderately stout, truncate ; terminal clasp segment somewhat 

 swollen basally, strongly curved apically ; dorsal plate long, deeply and tri- 

 angularly incised, the lobes tapering ta a narrowly rounded, sparsely setose 

 apex ; ventral plate long, broad, broadly and roundly emarginate, the lobes 

 sparsely setose. Harpes rather long, slender, with a long, stout, chitinous 

 process apically ; style rather long, broad, truncate distally. 



Female. — Length 1.4 mm. Antennae extending to the base of the ab- 

 domen, sparsely haired, fuscous yellowish; 12 subsessile segments, the fifth 

 subcylindric, with a length about twice its diameter, tapering slightly distally, 

 with a sparse subbasal whorl of moderately stout setae and a scattering sub- 

 apical band of longer, more slender setae ; terminal segment reduced, sub-
