 erect hairs. Scutellum as broad as long, feebly triangular, broadly

 erect hairs. 



Abdomen beneath finely, sparsely, vaguely punctate, rather densely 

 clothed with long, inconspicuous, recumbent pubescence ; last segment

Bemarks. — Described from three examples (one type), all collected 

 at light, at the type locality, by H. L. Dozier: The type, collected 

 February 17, 1930, and labeled "Ace. 55-30 " ; one paratype, collected 

 December 31, 1929; and one paratype, collected February 10, 1930, 

 and labeled "Ace. 36-30." Sexes not determined. 



This species is closely allied to necydalea Fabricius, but it can be 

 separated from that species in being uniformly pale yellow above and 

 in having the eyes practically divided.

 dibles short, arcuate, and rather acute at apices. Ligula membranous

 longer than the body in both sexes, not spinose, not ciliate beneath ;

 the third joint. Antennal tubercles not spinose at apices. Eyes
