 the fifth to tenth joints less produced on one side at apex, 

 and shorter legs with thinner tarsi.

A very thin species, at first glance somewhat suggestive 

 of Stephanops, but with the muzzle of normal length. The 

 clothing of the prothorax is somewhat as on discicollis, but 

 the tips of the elytra are utterly different, and, in fact, the 

 species is not very close to any other in the Museum. On 

 the head the pubescence is dense between the eyes; on the 

 prothorax it is condensed into four conspicuous vittae, with' 

 the intervening spaces polished and almost glabrous ; on the 

 elytra the pubescence is dense at the base on the sutural 

 half for a short distance, but is narrowly continued along the 

 suture, on each side the dense pubescence is rather narrow, 

 but is somewhat dilated at about the basal third ; the rest of 

 the elytra is very sparsely clothed; as a result, to the naked 

 eye, the elytra appear to be conspicuously brown, with three 

 narrow whitish lines ; on the under-surface the white pub- 

 escence is much denser at the sides of the sterna than else- 

 where. The prothorax is about twice as long as its apical 

 width. The elytra (except for the suture and margins) are 

 without elevated lines; their tips are unusually acutely armed, 

 but the sutural spine varies somewhat; the outer one, how- 

 ever, appears to be always long and acute. The males are 

 without sexual adornment of the femora, but in addition to 

 the differences noted above their antennae are clothed with a 

 fringe of pubescence projecting downwards (the fringe is very 

 fine, but is quite distinct in a good light) ; on the female this 

 is represented by a few sparse setae only.
