BLEPHARIPA POLITANA Townsend. 



Blepharipa politana Townsend, Ann. Ent. Soc. Amer., vol. 4, 1911, p. 132.— 

 TD 3977. 



Length of body, 9 to 10 mm,; of wing, 7 to 8 mm. Numerous 

 females, Piura, Peru, June 19 to November 3, 1910, on foliage. 



Whole front, face, cheeks, and orbits light golden pollinose, the 

 occiput ashy pollinose, the frontalia brown. Third antennal joint 

 and arista brown; first two antennal joints and palpi yellowish- 

 brown. Thorax, scutellum, and abdomen thickly silvery-cinereous 

 pollinose, the usual five vittae on mesoscutum, and a dark median 

 line on abdomen. First abdominal segment largely blackish, the 

 hind borders of second and third segments dusky, the anal segment 

 wholly golden pollinose like the head. The sides of abdomen show 

 more or less distinctly reddish. The first abdominal segment is 

 without median macrochaetse, and with at most very small lateral 

 ones. Second segment has at most a very weak median marginal 

 pair, sometimes hardly to be differentiated from the bristly hairs; 

 it has a distinct lateral macrochseta. The third segment has a mar- 

 ginal row of 10 strong bristles. There are 4 sternopleural and 4 

 postsutural bristles. The ocellar bristles are very small but distinct.^ 

 The scutellar bristles are 4 marginal pairs, the one next to the basal 

 much shorter than the others, the apical pair not decussate, a short 

 discal pair present.

Genus BRACHYMASICERA Townsend. 

 Brachymasicera Townsend, Ann. Ent. Soc. Amer., vol. 4, 1911, pp. 133, 143. 



General external characters of Masicera and Sisyropa. Eyes 

 thinly hairy. Facialia ciliate less than half way up, but truly ciliate 

 on more than lower one-third. Vibrissae quite on level with oral 

 margin, latter cut off and but very slightly produced. Second anten- 

 nal joint short, proboscis short and fleshy, palpi elongate and club- 

 shaped, third antennal joint four times as long in female as the short 

 second. Front and face almost equilateral (female), the latter only 

 perceptibly widened, about one and one-half times as wdde as one 

 eye. Female with two proclinate orbital bristles, and two reclinate 

 ones inside these. Long proclinate pair of ocellar bristles. Arista 

 thickened only on basal one-fourth. 



Two sternopleural bristles, sometimes a very weak third one be- 

 tween them. Three postsutural bristles, not counting one behind 

 which is outside the line of the others and does not properly belong 

 with them. Three strong lateral pairs of scutellar bristles, the pos-
