disappearing distally ; skin coarsely shagreened ; each of the abdominal 

 segments at least, with a sparse row of long spines near the middle; 

 terminal segment broadly rounded; a submedian pair of heavy, 

 chitinous spurs, a pair of minor transparent processes and a sub- 

 lateral pair of long, stout setae. 



This larva does not appear like that of a typical Lasioptera, 

 it may be a Dasyneura. 



Female. Length .9 mm. Antennae brownish black; 18 or 19 

 segments, the fifth with a length a little greater than the diameter; 

 terminal segment obconical, the apex rather obtuse. Palpi; the 

 first segment sub quadrate, the second a little longer, the third 

 about as long as the second, both rather stout, the fourth one-half 

 longer than the preceding, more slender. Mesonotum brownish 

 yellow, yellowish posteriorly, submedian lines broad, narrowly 

 separated, the median line shorter. Scutellum yellow, postscutellum 

 yellowish. Abdomen dark brown with the first segment golden, 

 the others yellow-banded apically, ovipositor yellowish. Wings 

 hyaline, costa dark brown, thickly clothed with scales basally, the 

 third vein uniting with the margin at- the basal third. Hal teres 

 yellow, large. Coxae whitish transparent, femora pale, tibiae 

 pale brownish above toward the apex, tarsi brown; claws rather 

 slender, strongly curved. Ovipositor as long as the body, the

The female representing this species was reared September 11, 

 1907 from specimens ofRudbeckia lacineata bearing galls 

 of Asphondylia conspicua O. S., and received from 

 Highspire, Pa. A species of Torymus was also obtained. 



Female. Length 1.5 mm. Antennae dark brown, the basal 

 segments whitish; 23 segments, the fifth with a length about three- 

 fourths its diameter; terminal segment slightly produced, broadly 

 oval. Palpi; first segment short, stout, irregularly subquadrate, 

 the second rather stout, with a length about three times its diameter, 

 narrowly oval, the third one-third longer than the second, slender, 

 the fourth about as long as the third. Face whitish. Mesonotum 

 dark brown, variably margined anteriorly and laterally with silvery 

 hairs, the submedian lines gray haired. Scutellum and postscutellum 

 dark brown. Abdomen dark brown, the basal segment silvery 

 white dorsally, the third and fourth segments narrowly margined 

 posteriorly with silvery white, the markings obsolete laterally, 

 venter silvery white; ovipositor pale yellowish. Wings hyaline, 

 costa dark brown, the third vein uniting at the rather long, whitish 

 discal spot just before the basal half. Halteres and coxae pale 

 yellowish; femora and tibiae dark brown, yellowish at the extremities, 

 especially the distal third of tibiae; tarsi dark brown, the first '
