The generic characters are of such a nature as render- any detailed description of the 

 unique species unnecessary. The margin <>f the bodj is fringed with -hurt hair-, the sur- 

 face black, but denselj clothed with ash-colored scales. On the elytra the vestiture i- less 

 dense, and three series of rounded spots are visible on each elytron, in which the scales 

 are paler and inure densely placed. The under surface and legs are paler and the scales 

 sparselj scattered.
