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- 

 hiscent; the apex obliquely truncate, with the angles 

 scarcely produced ; the form of the elytra, and their 

 glassy discs, show an approach towards Odontocera.
