impressed line, which is sometimes very faint and often 

 obliterated posteriorly ; the whole surface is punctate with a 

 mixture of finer and coarser punctures, the former being more 

 numerous on the central area and on the lateral areas, where 

 some punctures have coalesced, especially along the margins • on 

 each side of the longitudinal central line the surface is very 

 slightly depressed, in some specimens more so than in others ; 

 pronotal blackish round spots are disposed as follows : on the 

 central area, on each side of the longitudinal middle line, a 

 comparatively large and often prominent spot; a little posterior 

 to it, but exactly on the middle line, a small spot, and one on 

 each side, generally on the depression. Scutellum triangular

with apex rounded ; .surface rough, finely punctate and sometimes 

 with a depression. Elytra slightly broader at the base than the 

 prothorax ; humerus convex, prominent, and just within it there 

 is a deep depression ; the whole surface is closely and strongly 

 punctate near the suture and on the basal area there is a 

 tendency for the punctures to form longitudinal rows ; posterior 

 to the humerus is an ill-defined rib, the interstices generally are 

 not smooth ; the marginal area posterior to the humerus is rugose ; 

 along the margin lies a slightly raised, impunctate, but more or 

 less rugose border, followed by a longitudinal row of punctures 

 along the extreme edge. Underside-, the surface generally is 

 transversely strigose, one or two abdominal sternites may have
