Long. corp. 2| lin., lat. 1| lin. 



Oblong-ovate, broad, robust, impubescent, punctate-striate, of a 

 flavous colour. Head transverse, abbreviated, not produced in front ; 

 below the base of the antennas is a transverse triangular depression 

 (impunctate and glabrous) ; between the eyes is a short longitudinal 

 fovea, bisecting at its upper extremity another transverse depression, 

 thus forming together the character of the letter T ; eyes globose, 

 extending laterally not quite so far as the base of the head ; the sur- 

 face is very finely punctate. Thorax transverse, rectangular ; the 

 anterior angles depressed and well-defined; the sides finely niargi- 

 nate and rectilinear ; the surface is equate, clothed sparingly with a 

 very fine pubescence. Scutellum triangular, impunctate, and black. 

 Elytra broader than the thorax, robust, distinctly punctate-striate ; 

 flavous, with an almost circular black marking near the scutellum, 

 extending laterally on either side to the seventh stria, and (in the 

 direction of the apex) the distance of one-third of the whole length 

 of the elytra : another marking at the apex is also common to both 

 elytra ; its upper margin commencing medially, at the sides, extends 

 obliquely towards the suture ; this apical marking is interrupted at 

 the suture by the distance on either side of one stria. Antenna 

 filiform, robust (subincrassated), flavous, the fifth and sixth joints 

 being suffused with fuscous. Legs flavous; the posterior femora 

 being fuscous (suffused at the base with rufo-flavous), and the glo- 

 bular inflation on the posterior claw brightly rufo-fuscous. 



This beautiful species is from the district of the River Amazon.

 and the Rev. H. Clark.
