This species is easily recognisable by the sharply defined red 
mark resembling a widely open V on the disc of the almost black 
elytra.

Resembles the preceding but apparently a good species; it 
differs chiefly by its larger size, broader build, and the fainter 
impression of the sutural stria which commences evidently

very different form. Resembles also in general appearance 
Litochrus maculatus, Blackb.
