31 — Obtusely oval, the head pale in the male but sinuately black at base, the pronotum 

 black with a narrow parallel pale side-margin ; elytra sparsely and very finely

32 — Evenly elliptical, subdepressed ; sides of the pronotum in the female narrowly

 punctate, with feeble nubilous marginal pale streak at the humeral angles and a 

 very small, transversely oval, obscure yellowish and nubilous subapical spot re-

33 — Elytra with a pale spot very near the basal margin and inner third 34 



Elytra without a subbasal pale spot, the subcentral spot generally more or less elon" 

 gate-oval 35 



34 — Punctures of the elytra fine ; head and a narrow lateral and apical margin of the 

 pronotum pale in the male ; elytra with a humeral and a median elongate margi-

Punctures of the elytra rather coarse and deeply impressed, somewhat sparser ; orna-

35 — Elytra with a narrow, internally sinuate marginal pale vitta extending two- thirds 

 to three-fourths from the base, the vitta frequently wholly wanting 36 



Elytra with an entire marginal vitta, internally bisinuate, not extending quite to the 

 suture and which is never wanting but sometimes resolved by individual varia- 

 tion into three separate spots 37 



36 — Subapical spot smaller and slightly elongate-subquadrate, less distant from the 

 suture than from the limb ; discal spot at basal third almost equidistant from 

 suture and margin, the punctures fine and rather close-set ; head and pronotal
