■Vertex shining impunctate, front impressed on either side, 

 just above the encarpa;, with a deep round fovea, in the middle, 

 continuous with the sutural line separating the encarpa? is a short 

 longitudinal groove ; encarpa^ transverse, contiguous ; carina short, 

 thickened, its apex acute; antenna? filiform, about three-fourths 

 the length of the body. Thorax twice as broad as long ; sides 

 rather broadly margined, straight and converging from the base 

 nearly to the middle, rounded and slightly dilated in front of 

 the latter, the anterior angles excavated, obtuse; very sparingly 

 ])unctured above, the pimctures irregidarly scattered here and 

 there over the surface ; middle disc impunctate ; transverse 

 groove distinct on either side and extending to the lateral 

 mai'gin, nearly obsolete on the medial line. Elytra broader 

 than the thorax, rather closely punctured, each with four rather 

 large subrotundate spots; two placed on the inner disc near the 

 suture, one just below the base, the other at some distance just 

 below the middle, the two others near the lateral margin, the 

 first below the humeral callus, the second about half-way 

 IjetAveen the middle and the apex; these spots taken conjointly 

 with those on the opposite elytron form two curved fascia?, one 

 before, the other behind the middle. Body beneath Avith the 

 breast and two large spots placed transversely on each of the 

 abdominal segments (the anal one excepted) lilack. Claws
