Type and parahjpe.— Cat. No. 15307, U.S.N.M. 



Two females, Huancabamba, Peru, September 6. 1911 (C. H. T. 

 Townsend). 



Allied to miniusculum Lutz, but he makes no mention of the glossy 

 apical abdominal segments, though they probably are of that color 

 in his species, and he gives the abdominal hairs as pale. The size of 

 the species he describes is also less, 1-1 1 mm. and the locaHty Brazil.

 Plate 46, fig. 1. 



Male. — Frons brownish yellow, blackened from anterior orbital 

 bristles, narrowly, on ocellar triangle, and on vertex, opaque except 

 on those parts, on center and on the bases of the central rows of bris- 

 tles; lower orbital bristle at middle, very near to second pair, second 

 about five times as far from upper pair as from lower, ocellar bristles 

 widely divergent, only two pairs of weak centrals; behind ocellar 

 region on each side and at base of each of the vertical row of bristles 

 there is a white pollinose spot. Face produced between antennae, 

 distinctly shining on upper and lower margins, subopaque and paler 

 yeUow on center, concave in profile; cheeks yellow, subopaque, at 

 center about one- third as high as eye at center, anterior vibrissa 

 strong, incurved; posterior to it and almost below center of eye a 

 strong upcurved bristle, and on the oral margin numerous hair-like 

 bristles. Antennas brownish, third joint rounded, second joint with 

 several bristles, thu-d with short pale pilosity; arista distinctly 

 pubescent, about one-third longer than the breadth of frons. Meso- 

 notum black, a series of four white pollinose spots in center, the first 

 on the anterior margin and the last just in front of the scutellum, an 

 irregular stripe of same color from the inner angle of humerus, which 

 stops short of the anterior dorso-central bristle, at the base of which 

 as well as of the posterior pair there is a pollinose spot; other spots are 

 on the humeri, immediately behind humeri, posterior to the last but 

 nearer to center of disk, and one above wing base; the region m front
