covering, some short, slender, more or less erect strigose scales 

 or scale-like hairs. The unique type has the fifth ventral flat 

 and narrowly parabolic in outline. The contrast between the 

 evenly imbricate flat, and the dual A'estiture of the convex inter- 

 vals, is very striking.

 smooth and densely squamose. Head not separated from the 

 beak by a transverse depression, having a minute interocular

 head, longer than wide, feebly- dilated at apex, the alse broadly 

 rounded. Mentum large, filling the entire buccal opening. Scrobes 

 narrow, deep and well defined throughout, obliquel}^ descending

 thick and short, gradually enlarged at apex, extending beyond 

 the middle of the eyes ; funicle long but somewhat thick, filiform, 

 the two basal joints longer, the second longer than the first and 

 about twice as long as wide ; three to six equal and only slightly 

 longer than wide ; seventh slightly- thicker and much longer than 

 the sixth, obconical ; club well developed, fusiform, somewhat 

 obliquely pointed, as long as joints four to six of the funicle 

 combined, and about twice as thick. Ocular lobes completely 

 obsolete and with the edge not at all fimbriate. Scutellum \evy
