Four new Gall Midges (Dipt.)- 



By E. P. FELT, Albany, N. Y. 



The four species described below, including the representa- 

 tive of a new genus, were reared by Mr. W. H. Patterson, St. 

 Vincent, W. I. Our knowledge of the gall midges of Tropi- 

 cal America is exceedingly fragmentary. Careful collecting 

 and rearing would result in the finding of numerous unknown 

 forms, some of which would doubtless throw much light upon 

 taxonomic questions. 



Asphondylia pattersoni n. sp. 



This reddish brown midge was reared February 3, 1911, 

 from the flowers of fiddlewood, Cltharc.vylnm quadrangular c. 



Male. Length, 1.75 mm. Antennae distinctly longer than the body, 

 sparsely haired, light brown ; 14 segments, the fifth cylindric, with a 

 length five times its diameter; terminal segment wanting. Palpi: first 

 segment subquadrate, the second with a length three times its diameter, 

 somewhat expanded distally, the third fusiform, slightly curved, as 

 long as the second. Mesonotum reddish-brown, the submedian lines an 

 obscure yellowish. Scutellum yellowish brown, postscutellum fuscous 

 yellowish. Abdomen rather thickly haired, yellowish brown, the basal 

 segments darker, the genitalia slightly darker than the apex of the 

 abdomen. Wings hyaline, costa light brown, the third vein uniting with 

 the margin at the apex of the wing. Femora and tibiae mostly dark- 

 brown ; claws moderately stout, strongly curved, simple, the pulvilli a 

 little shorter than the claws. Genitalia: basal clasp segment greatly 

 swollen, stout ; terminal clasp segment short, greatly swollen, bidentate 

 apically; dorsal plate divided, the lobes orbicular, sparsely setose. Other 

 organs indistinct. 



Female. Length 1.75 mm. Antennae a little shorter than the body, 

 sparsely haired, light brown : 14 segments, the fifth cylindric, with a 

 length about five times its diameter; the thirteenth segment subqua- 

 drate, the fourteenth subglobosc. Palpi : first segment short, sub- 

 quadrate, the second subglobose. the third with a length four times its 

 diameter and somewhat dilated. Ovipositor, when extended, about as 

 long as the abdomen, the aciculate portion moderately stout ; dorsal 

 pouch apparently represented by an indistinct, thickly setose lobe hardly 

 comparable with the highly developed organ observable in most species 

 of Asphondylia.
