Female. — Front and vertex three times longer than wide; oceUi in 

 a strongly acute-angled triangle, the posterior pair almost touching 

 eye margin and about then* own diameter apart; antennal scrobes 

 broad and shallow; eyes nonpubescent. Antennal scape strongly 

 flattened but not expanded below, the lower margin gently curved, 

 a little over four times as long as wide; pedicel as long as the first 

 three and one-half of the fourth funicle joint combined; first three 

 funicle joints equal in length, the fourth slightly longer, the last two 

 equal and a little longer than the fourth, all increasing gradually and 

 shghtly in width distad, the sixth about one-haK wider again than 

 the first, the first three a Uttle wider than long, the sixth considerably 

 so, but the fourth and fifth about as long as wide; club elongate oval, 

 tapering distad, and slightly obliquely truncate at apex, one-third 

 wider again than the preceding joint and as long as the last five 

 funicle joints combined. Wings uniformly cihated; oblique hairless 

 streak not reaching to the stigmal vein and interrupted below, the 

 small cut-off portion well separated from the posterior margin of 

 disk and from the basal streak; the latter reaching nearly to the 

 angulation or to a point opposite the end of the stigmal vein. Ovi- 

 positor protruded about one-eighth the length of the abdomen. 

 Length: 0.9 mm., exclusive of ovipositor. 



Front, most of occiput, face, and cheeks pale chrome yellow, be-
