 curving backward and outward; frontals in two irregular rows, the 

 inner or main row extending below the middle of second antennal

 or two pairs directed inward, the latter reclinate ; ocellar bristles well 

 developed, proclinate ; orbitals absent ; face including cheeks pale in 

 ground color, with white subshining pollen; parafacial rather broad, 

 bearing a single stout bristle near the lower corner of eye (in one 

 specimen two, but the lower one small) and sparsely clothed with

 thirds the eye height, clothed with fine pale and coarser black hairs; 

 proboscis distinctly exceeding the height of the head, apical segment 

 slender, shining brownish black, labella small; palpi absent; antennae 

 three-fourths the length of face, largely red, third segment unusually 

 broad, strong convex on the anterior margin and about one and one- 

 half times the lengih of second segment; arista blackish, thickened 

 and tapering toward tip, penultimate segment long, the apical one 

 pubescent and somewhat flattened near base; back of head gray 

 pollinose and densely clothed with white hairs. 



Thorax black; mesonotuni gray pollinose, marked with four broad 

 black stripes which extend almost to base of scutellum; prosternum 

 bare; pleura gray pollinose, clothed with fine pale hairs; scutellum 

 reddish on apex, covered with changeable gray pollen. Chaetotaxy :

 acrostichal, 3, 3; dorsocentral, 3, 4; intraalar, 3; supraalar, 3; post- 

 alar, 2; pteropleural, 2; sternopleural, 2, 1; scutellum bearing two 

 large lateral, a much smaller suberect decussate apical, and a discal 

 pair; postscutellum normal; calypters opaque, white. 



Abdomen rather slender, subshining, black, the sides and apex 

 reddish with rather thin changeable gray pollen, which extends to the 

 hind margins of the intermediate segments; first segment pollinose 

 above, without median marginal bristles; second with a stout pair; 

 third bearing a median pair and three at the side; fourth segment 

 with three irregular rows on apical half; venter gray pollinose, black- 

 haired with pale pile on basal segment; genitalia yellow, with the 

 usual large lobe on the side ; the united inner forceps short, clothed 

 with black hairs on base behind, laterally compressed or very thin on 

 about apical third, in profile view uncommonly thick to apex which 

 is broadly rounded; outer forceps blackish, with a large triangular 

 projection near base behind, rather slender beyond and in rear view 

 strongly bowed ; penis short, the apex broadly expanded ; fifth ster-
