Long. corp. 2|— 2| lin., lat. 1 lin. 



Oblong-ovate, somewhat more robust than the allied species ; sub- 

 parallel, clothed throughout with a fine flavous pubescence, in colour 

 flavo-fuscous. Head broadly produced in front, the extreme apex 

 being abruptly contracted ; a well-defined carination extends me- 

 dially from the base of the antennae to the labrum ; above the an- 

 tennae are two medial oblong tubercles, which are separated one from 

 the other by a distinct fovea : the eyes are large and subglobose, in 

 form oval, lateral ; the base of the head is punctate, being clothed 

 near the margins of the eyes with obsolete flavous pubescence ; in 

 colour the surface is in front pale flavous (the extreme apex being 

 black), the base is rufo-flavous. Thorax not so elongate as in most 

 of the species of this group, almost quadrate ; the sides are finely 

 but evenly marginate, broadly constricted at the apex, and parallel 

 at the base ; the surface is broadly transversely depressed at the 

 base, and clothed throughout, but most distinctly at the base, 

 with flavous pubescence. Scutellum obscure, triangular, clothed 

 throughout with thick fusco-flavous pubescence. Elytra sufficiently 

 robust, parallel, punctate-striate ; the surface is in colour rufo- 

 fuscous, and clothed for the most part with thick flavous pubescence : 

 between the third and fifth stria?, near the margination (and also 

 more narrowly at the suture), are two longitudinal markings of fus- 

 cous colour, caused by the absence of pubescence ; these markings do 

 not extend to the apex, and are irregular in outline. Antenna} ro- 

 bust, filiform, rufo-fuscous. Legs flavous throughout. 



R. neglectus may be separated from its congeners by its quadrate 

 (hardly elongate) thorax, in the form of which it approaches B. nigri- 

 comis, as well as in the rufo-flavous colour and thick flavous pubes- 

 cence of its elytra.

A beautiful variety of this species is in Mr. Fry's collection, taken 

 by him in the neighbourhood of Rio Janeiro. It is smaller than the 

 described species, being 2\ lines in length ; it is more brightly 

 flavous in colour, and covered throughout with a very fine flavous
