form) into two slightly elevated tubercles ; surface punctate, rufo- 

 fuscous, — the raised anterior surface and the sides being rufous. 

 Scutellum triangular, fuscous. Elytra broader than the thorax, de- 

 pressed, punctate-striate, subpubescent, rufo-fuscous, — the shoulders 

 (from the humeral angle to the scutellum), and also a broad, suffused, 

 transverse band {near to the apex), being rufo -flavous. Antenna? 

 filiform, tolerably long, flavous, with the sixth and eleventh joints 

 fuscous. Legs flavous, the posterior femora being pubescent, and 

 suffused with dark fuscous ; the inflation of the terminal claw bright 

 rufo-ferrugineous. 



This species may be separated from those nearly allied to it (all of 

 which, at first sight, closely resemble one another) by the form of, 

 and the markings on, the surface of the thorax. 



From the Amazon district. Taken by Mr. Bates.

Oblong-ovate, subparallel, pubescent, darkly fuscous. Head short, 

 abruptly depressed and slightly produced : between the labrum and 

 the base of the antennae is a triangular glabrous plane, which is bi- 

 sected by a medial longitudinal carination ; the base of the antennas 

 is situated immediately on the angle of abrupt deflection, giving it 

 the appearance, when viewed laterally, of a Loxoprosopus : eyes large, 

 situated at the base of the head, extending laterally beyond the 

 anterior angles of the thorax ; the surface above the base of the an- 

 tenna? finely granulated ; the colour of the labrum rufo-flavous, of the 

 head black. Thorax quadrate ; the anterior angles subtruncate ; the 

 sides marginate, and slightly constricted towards the base : a broad 

 transverse depression (which is well-defined and abrupt at its upper 

 margin) extends along the line of the base ; this depression is most 

 narrow mediahY, becoming slightly broader as it approaches the 

 margination : the surface subdepressed, very finely pubescent, fus- 

 cous, with a broad lateral margination of flavous. Scutellum small, 

 triangular, fuscous. Elytra subcyliudrical, punctate-striate, finely
