The midge was reared June 15, 1907 from a conical petiole gall 

 on grape, collected on Staten Island, N. Y. The gall is quite com- 

 mon in the vicinity of New York City, also at West Nyack, N. Y. 

 It was found on Isabella grape by Mrs M. Archer Shee, Highland 

 Falls, N. Y., and taken on grape at Albany, N. Y. The species 

 was reared by the late Dr M. T. Thompson, Worcester, Mass., and 

 presumably at Washington, D. C, as specimens dated April 28, 

 1888 are in the collections of the National Museum. Trichasis 

 virginiensis Ashm. was reared from this gall. 



Gall (pi. 3, fig. 2). This is an obpyriform or slightly curved coni- 

 cal petiole gall on grape. The enlargement is about 1.5 cm long and 

 .5 cm in diameter. Each gall contains 2-4 larvae in along central 

 chamber. 



Larva. Length 3.5 mm, stout, whitish or pale yellowish. Head 

 small; antennae uniarticulate ; breastbone linear, bidentate, with 

 a minute median tooth and tapering slightly distally; skin coarsely 

 shagreened; posterior extremity broadly rounded. 



Male. Length 2.5 mm. Antennae dark brown, basally yellowish; 

 20 segments, the fifth with a length about three-fourths its diameter; 

 terminal segment greatly prolonged, subconic with a length fully 

 twice its diameter, the base slightly rounded, the apex obtuse. 

 Palpi fuscous yellowish, the first segment stout, sub quadrate, slightly 

 swollen distally, the second a little longer than the first, stout, roundly
