It is rather dark red in colour and very shining, with 

 the pubescence short and scarcely traceable except upon 

 the head and towards the extremities of the elytra. It 

 is rather oblong in shape and the pronotum is broad in 

 front and parallel-sided behind, with a deep basal groove 

 not very close to the margin, and the elevated lateral 

 margins very broad in front but considerably narrowed 

 behind. The elytra are finely bvit distinctly seriate- 

 punctate. The antennae are slender, with the 2nd to 

 the 10th joints spherical, the last three large and the 

 terminal one elongate-oval. 



Probably in the quite fresh state the body is rather 

 more hairy than in the unique type specimen, but this 

 latter is otherwise in perfect cojidition.

This is the second described species of a peculiar genus, 

 of which the elevated sides of the pronotum, as well as 

 the hairy surface, indicate a relationship to Stenotarsus, 

 but the antennae are markedly different from those of all 

 other genera of the family hitherto described. There is 

 no transition from footstalk to club, but the latter is very 

 abrupt, and pectinate in form, its three joints being loosely 

 connected at their outer sides, the two basal ones strongly
