 Long. corp. 3|-3f lin., lat. If lin. 



Oblong-ovate, robust, subcylindrical, subelongate, covered for the 

 most part with a fine flavons pile ; black. Head short, transverse, 

 produced broadly in front ; above the labrurn, extending to the base 

 of the antenna?, is a longitudinal medial carination, divided at the 

 insertion of the antenna?, and thence taking on either side an oblique 

 direction ; near the labrum (extending to this medial ridge) are two 

 other oblique carinations ; immediately above the insertion of the 

 antennae (adjoining the inner surface of the eyes) are two minute 

 depressions ; eyes tolerably large, situated nearly at the base of the 

 head ; the surface granulated, rufous, suffused (especially in front) 

 with fuscous, the labrum being flavo-rufous. Thorax quadrate (almost 

 elongate), broader than the head, but constricted towards the apex, 

 so as to meet anteriorly (and almost in the same line) the lateral 

 margin of the head ; the surface is depressed (as compared with the 

 surface of the elytra) ; the anterior angles are almost obsolete, and 

 much depressed as well as constricted; the sides are faintly marginate; 

 at the base (when viewed laterally) is an obsolete transverse de- 

 pression ; the surface is finely punctate, darkly rufous, and covered 

 (probably) throughout with a fine thick flavous pubescence. Scutellum 

 triangular, impunctate, fusco-pubescent. Elytra considerably broader 

 and more robust than the thorax, subattenuated towards the apex, 

 punctate-striate (the stria? being obsolete and the punctures deeply 

 impressed and distinct) ; at the shoulders, near the seventh stria, is 

 a short and well-defined longitudinal channel, which gives a square 

 and well-developed form to the extreme apex of the shoulder ; the 

 sm'face is clothed throughout with a thick flavo-fulvous pubescence, 

 except near the scutellary angles, where a considerable surface 

 (denuded of this pubescence), of a circular form, is glabrous and black; 

 also, postmedially, a transverse regidarly defined fascia is formed 

 (broadest near the suture) by a similar absence of this pubescence ; 

 at the shoulders (at the extreme apex) is an obscure suffused spot 

 of rufous. Abdomen rufo-ferrugineous. Antennae robust, filiform, 

 fuscous, the basal joint being rufo-fuscous. Legs clothed, more 

 sparingly than the elytra, with flavous pubescence ; the anterior 

 fuscous, sparingly suffused with rufous; the posterior rufous, the base 

 of the tibia? and the inflated posterior claw being rufo-fuscous. 



Taken by Spix and Martius in the Minas province (Serra do Caraca), 

 and by others sparingly in the neighbourhood of Rio Janeiro.
