Head moderate, antennae rather long, with the intermediate joints very slender, 



sixth joint much longer but not broader than the seventh, club very much 



incrassated. 

 Thorax short, produced in front, not semicircular, widest at the base, flavescent and 



very shining, indistinctly punctured, basal margin deeply sinuated, with the 



angles acute and much pi'oduced. 

 Scutellum moderate, rounded, faintly asperate. 

 Elytra oval, slightly attenuated posteriorly, one-half longer but not broader than 



the thorax, widest at the shoulders, moderately but closelj^ asperated in nearly 



straight transverse rows, with a stria on each side of the suture, extremities

 Differs from others in the shape of its thorax, longer elytra, longer, more slender, 



and diversely formed antennae.

uncommonly ; Guatemala, Panajachel (Champion) one specimen.

margin deeply sinuated and much produced towards the scutellum, with the

 Scutellum very short and much rounded. 

 Ehjtra more than one-half longer but not broader than the thorax, widest at the

rather short and very robust antennae, of which the seventh joint is as large as 



or larger than the sixth.

South of England, probably in Oxfordshire, but I have no note of the exact 



locality.
