segments basally, and ovipositor more or less yellowish, ventral sur- 

 face suffused with silvery white scales. Wings hyaline, costa dark 

 brown, the discal spot yellowish white, the third vein uniting with 

 costa near the basal third. Halteres semitransparent, light orange

 lations and the tarsal segments basally, narrowly banded with yel- 

 lowish white, rather broadly so on the posterior legs; claws rather 

 long, stout, strongly curved, the pulvilli nearly as long as the claws.

The oval stem gall inhabited by the larva of this fly is rather 

 common on bugleweed (L y c o p u s c o m m u n i s) in the vicinity 

 of Albany and presumably in other localities in the Hudson valley, 

 as specimens were taken at Shushan, N. Y., by Prof. C. H. Peck 

 while Professor Beutenmueller records it from White Plains. The 

 pale orange larvae winter in the gall, the adults appearing about 

 the middle of May. Eritrissomerus noveboracensis 

 Brues and a species of Torymus were reared from this midge. 



Gall. The stem gall inhabited by this form is light green, 

 round or subglobular, 8 to 10 mm long, 2.5 mm in diameter and 

 within there is an elongate chamber containing the larva. 



Larva. Length 3 mm, slender, pale orange. Head small, antennae 

 stout; breastbone slender, distinctly expanded apically, minutely 

 tridentate; skin rather coarsely shagreened; posterior extremity 

 broadly rounded. 



Male. Length 2.25 mm. Antennae dark brown, basally yellowish ; 

 16 segments, the fifth with a length about one-fourth greater than 

 the diameter; terminal segment somewhat reduced, broadly oval. 

 Palpi; the first segment short, stout, subquadrate, the second one- 

 half longer, narrowly oval, the third slender, one-fourth longer 

 than the second, the fourth about as long as the third, flattened, 

 broader. Face rather thickly clothed with silvery white hairs, 

 eyes black, narrowly margined posteriorly with silvery white. 

 Mesonotum dark brown, variably margined laterally and anteriorly 

 with silvery white, the submedian lines rather sparsely clothed 

 with yellowish setae. Scutellum dark brown, a few coarse setae 

 and whitish scales apically, post scutellum dark brown. Abdomen 

 dark brown, basal segment broadly margined posteriorly with 

 silvery white, the second to seventh segments with submedian 

 lunate, silvery spots on the posterior margins of the segments and 

 with smaller, oval spots laterally; genitalia fuscous, venter variably 

 clothed with silverv scales, with irregular submedian dark brown
