ments with a lateral bristle and a median marginal pair; third with a marginal 

 row of macrochffitae, anal with marginal and submarginal bristles. Legs black, 

 front femora very faintly silvery, claws and pulvilli short. Wings grayish hya- 

 line, a very slight wrinkle at bend of fourth vein ; tegnlte white, posterior scales 

 saturated ; halteres fuscous. Length of body 5 mm. ; of wing 4 mm. 



Described from one specimen ; Ottawa, Can. Bred by Mr. W. 

 Hague Harrington from saw-fly larva (Nematust). Issued July. 

 This is one of those species which should be excluded from the genus 

 Mcisicera, on account of the facial ridges being bristly half way or 

 more from vibrissje to base of antenn?e.

 pression and cheeks silvery, epistoma more or less tawny rufous ; vibrissse in- 

 serted nearly on oral margin, facial ridges ciliate nearly to lowest frontal bristles ; 

 antennPB nearly reaching epistoma. black, third joint about five times as long as 

 second ; arista black, thickened on basal half; proboscis brownish, palpi rufous

 and pleuriB silvery; scutellum silvery black at base, apex rufous. Abdomen 

 shining black, segments two to four silvery white poUinose except hind margin, 

 second segment red on sides, also adjacent parts of first and third segments;

 of body, 4i — 5i mm.; of wing, 4 — 4h mm. 



Described from two specimens; Morgan town, W. Va. Bred by 

 Mr. A. D. Hopkins from Sphingid larvse. This species also should 

 be separated from this genus on account of the ciliate facial ridges.
