 stripe with a silky lustre, anterior margin obscurely brownish; 

 antennae reddish, third joint brown on upper surface; arista brown; 

 face brown; cheeks glossy black-brown; proboscis brown, apical 

 portion pale yellowish; palpi reddish. Thorax without any indi- 

 cation of dusting either on disk or pleurae. Abdomen glossy black 

 on dorsum, especially on apical half, venter opaque brown. Legs

Frons slightly over one-third the width of head; triangle oc- 

 cupying two-thirds the width of vertex, and extending slightly over 

 two-thirds to anterior margin of frons; surface hairs sparse and 

 distinct; antennae of moderate size, third joint rounded; arista 

 pubescent, tapering, in length at least equal to width of frons; 

 cheeks almost linear, especially at anterior margin; marginal hairs 

 distinct, the upper strongest; proboscis and palpi normal; eyes dis- 

 tinctly higher than long, bare. Mesonotum without sulci, the 

 hairs very closely placed and, though in rows, not easily distinguish- 

 able as such, the base of each hair in a very minute puncture;

 species resembles one in Agromyza which occurs in North America.
