Moderately broad, ferruginous brown; head rather narrow, closely 
granulate; prothorax ferruginous at the sides, rather finely granulate, 
the margin slightly rounded, with a narrow elevated rugose line, as if 
composed of small confluent granules, the external costa entire, the 
inner forming an oblong loop posteriorly ; scutellum punctiform ; elytra 
oblong, not broader than the prothorax, the cost finely crenate, a large,

row of punctures; body beneath dark ferruginous, minutely punctured ; 
legs and antenn ferruginous. Length 1 line,
