Lasioptera tibialis Felt 



1 9 14 Felt, E. P. Insecutor Inscitiae Menstruus, 2:119-20 



The midges related to L. allioniae Felt were reared from a 

 stem or branch gall on Pentstemon antirrhinoides col- 

 lected by Mr E. P. VanDuzee near La Jolla, Cal. 



Lasioptera carbonitens Ckll. 

 1902 Cockerell, T. D. A. Can. Ent. 34:183 



The midge provisionally placed here produces an aborted shoot, 

 somewhat like a long onion bulb, on an unknown grass collected at 

 Las Vegas, N. M. The gall is characterized as being similar to 

 that of Brachy podium sylvaticum figured by Rub- 

 saamen in Ent. Nach., 21:16. See also under Asteromyia 

 agrostis O. S.

The midge was captured at Albany, N. Y., May 21, 1906, on 

 black alder, Ilex verticellata. 



Male. Length 1.5 mm. Antennae dark brown; 16 or 17 segments, 

 the fifth with a length greater than the diameter; terminal segment 

 subcorneal, slightly prolonged, obtuse. Palpi; the first segment 

 short, swollen distally, the second subrect angular, one-half longer 

 than the first, the third a little longer than the second, more slender, 

 the fourth, one-fourth longer than the third, more slender. 

 Mesonotum and scutellum dark brown, the latter silvery white 

 apically; postscutellum very dark brown. Abdomen dark brown, 

 rather thickly clothed dorsally with silvery white scales. Wings 

 (pi. 5, fig. 4) hyaline, anterior veins reddish brown, the third vein 

 uniting with the margin at the distal third. Halteres reddish 

 yellow. Legs mostly dark brown, lighter ventrally; tarsi darker 

 than femora and tibiae; claws stout, strongly curved. Genitalia 

 (pi. 7, fig. 1); basal clasp segment long, slender; terminal clasp 

 segment swollen basally; dorsal plate broad, deeply and roundly 

 emarginate, the lobes narrowly rounded; ventral plate narrow, 

 tapering, broadly rounded. Harpes subtriangular. Type Cecid. 73. 



Lasioptera argentisquamae Felt

This conspicuously marked form was reared from a considerable 

 lot of Solidago taken at West Nyack, N. Y. and bearing the character- 

 istic adhesive type of gall produced by A s p h o n d y 1 i a m o n - 

 a c h a O. S. and Camptoneuromyia adhesa Felt.
