The basal spot on each elytron is transversely subrotundate 
and is much nearer to the suture than to the external margin. 
The subapical spot is somewhat obliquely placed ; it is twice as 
long as wide, oval in form but with its front subtruncate, com- 
mencing not mueh behind the middle of the elytron and all but 
reaching the apex.
