 Head rather large, produced in front ; eyes large and prominent ; autennie rather 



large, rufo-testaceous, with the club dusky. 

 Thorax large, widest at the base, minutely and remotely punctured, w'ith the 



interstices shining but not alutaceous, sides and anterior angles rufescent,

nearly right angles. 

 Scutellum large, triangular. 

 Elytra scarcely broader, but one-half longer than the head and thorax, widest near

deeper punctation, the absence of the basal row of punctures on the thorax, 



and paler legs and antennje.
