There are two varieties of this species in the Museum collec- 

 tion ; in the first, the head, thorax, antennas and legs are of a 

 ferruginous brown, the elytra being ochraceous, the suture and 

 lateral margin brown ; in the second variety, the elytra are nearly 

 of a uniform black ; in other respects, however, these specimens 

 agree with the type as described above.
