Loewia rtificornis, n. sp., ^. 



Eyes cinnamon brown ; frontal vitta brown, much narrowed poster- 

 iorly, front at narrowest point about one-half its width at vertex; sides of 

 front, sides of face and facial depression black, thinly silvery-poUinose ; 

 cheeks blackish posteriorly, thinly silvery, the pregenal area very broad, 

 brown, extending upward between sides of face and facial depression ; 

 antennas and arista rufous, third antennal joint little more than one and 

 a half times as long as second, with a somewhat darker shade on outer 

 side ; proboscis brownish, palpi rather fuscous, tips rufous ; occiput black, 

 black-hairy. Thorax and scutellum shining black, black-hairy and bristly. 

 Abdomen shining dark metallic-green ; second segment with a median 

 marginal pair of macrochseiae, third with six or more marginal, anal with 

 about six marginal ; hypopygium rather exserted, concolorous. Legs 

 black, knees slightly rufous, front femora bristly ; claws and pulvilli 

 elongate, pulvilli smoky -whitish. Wings slightly grayish, nearly hyaline, 

 costo-basal portion and veins golden ; tegulee rather smoky-golden, 

 translucent; halteres clear yellow. 



Length of body, 6^ ram.; of wing, 5^2 mni. 



Described from one specimen; Constantine, Mich., August 27. This 

 species seems to connect the genera Loewia and Ejuiyoinma. The species 

 of Loewia usually have the eyes contiguous in the male, while in this 

 species they lack considerably of meeting, and the apical cell, though it 

 cannot be said to be open, is rather widely closed in margin, if the 

 expression may be allowed. In Ennyotnma the apical cell is open. 

 Loewia nigrifrons, n. sp., $. 



Differs from Z. globosa Twns. (Ent. News, III.) as follows : Sides of 

 front and sides of face shining black, not silvery ; facial depression slightly 

 silvery; pregenal area light-brownish; proboscis and palpi blackish.
