Of much less cylindrical form than the other species ; 
head narrower than the thorax, and the latter only half the 
width of the elytra. The elytra are far from being parallel 
sided, and are somewhat dilated about the middle of their 
length, and broadly rounded towards the apex ; in con- 
sequence of this form, the apical truncature is confined 
to a small portion of the apical margin near the suture, 
and the exterior spine is placed about the middle of the 
apex; the sutural spine is very small. The colour of the
