apex; each elytron has about seven impressed lines, 
those towards the sides somewhat obscure. Pygidium 
vermiculate, rugose at the apex. Sternal process very

A rather short, broad species, not very convex. 
Clypeus rather narrowed anteriorly, with the front part 
closely and strongly punctured. Thorax with punctua- 
tion, which is only seen with a high magnifying-glass, 
very strongly angular at the sides rather before the 
middle, slightly sinuate behind the angulation ; the sides 
yellow, with a large shallow impression, in the middle of 
which is a pitchy spot; the base only slightly sinuous, 
straight next the scutellum. Scutellum 25 millimetres 
long, arcuately narrowed posteriorly. Elytra yellowish 
red, at the base a little broader than the base of the 
thorax, a little wider behind the middle; the margins 
with the basal half impressed above, and very much 
thickened ; each elytron has ten strongly-impressed 
grooves, none of which (except the sutural one) reach 
the apex; the 7th, 8th, and 9th are short, terminating 
below the shoulder ; the 10th is marginal, and does not 
extend much beyond the middle ; the interstices are very 
convex, the alternate ones a little broader than the others. 
Sternal process long and thick, straight, but curved 
below, truncate at the apex.
