The elytra are broad at the apex, and truncate, with 
each angle briefly spinous ; they are distinctly narrowed 
in the middle, a little widened behind, and narrowed 
again to the apex, more so in the ? than in the $ . The 
basal sulphur-yellow vitta of the elytra is very variable in 
form, and is sometimes only a rounded spot.

The elytra are much narrowed, and are slightly de-

scarcely produced ; the form of the elytra, and their 
glassy discs, show an approach towards Odontocera.
