Female.—Reddish brown; 1.74 mm. long, 3.02 times as long as wide; 
subglabrous as seen from above except on declivity. 
Frons convex above, distinctly flattened below on semicircular

hairs of nearly even length; median line elevated into a broad, low 
carina, impunctate and brightly shining. Eye rather large, the facets
