PASTCHRESTTTS. 139 



1. Panchrestus pulcher. 



P. ovatus, rohustus, subpubescens, rufus, niticlus ; capite brevi, antice 

 subproducto, subtiliter granidato ; thorace transversa, ad latera 

 obsolete dentato, crebre punctato ; elytris brevibus, robustis, striato- 

 punctatis, sparsim fulvo-pubescentibus ; antennis brevibus, ad 

 apicem incrassatis, art. 1-5 flavis, 6-11 nigris; pedibus pallide 

 rufis aid flavis. 



Long. eorp. 2i lin., lat. 1^ lin. 



Ovate, robust, subpubescent, bright red, shining. Head short, de- 

 pressed (almost vertical), produced in front ; labrum black ; eyes tole- 

 rably large, distant, situate at the back of the head, and extending 

 laterally nearly to the anterior angle of the thorax ; surface closely 

 granulated and rufous. Thorax transverse ; the anterior angles de- 

 pressed ; the sides marginate and irregular in outline, projected ante- 

 medially in the form of a tooth ; surface coarsely and thickly punc- 

 tured. Scutellum very small. Elytra short, broad, robust, with 

 punctures arranged in the form of striae, bright rufous, clothed very 

 sparingly with fulvous pubescence. Antennce short, robust, incras- 

 sated towards the apex ; joints first to fifth flavous or fusco-flavous ; 

 sixth to eleventh considerably incrassated and black. Legs pale red 

 or flavous throughout. 



I cannot but feel it to be probable that this insect may (with others 

 hereafter to be discovered) constitute a separate genus : in its abbre- 

 viated form (its transverse thorax and robust elytra), coupled with 

 its short and incrassated antenna?, and the peculiar vertical form of 

 the head (which approaches to Loxoprosopus), not to mention the 

 lateral angular projection in the margination of the thorax, it pre- 

 sents several points of difference from its allies. 



From the district of the Amazon. Collected by Mr. Bates. 



2. Panchrestus rubicundus. B.M. 



P. ovatus, robustus, rufus, subpubescens; capite brevi, inter ocidos 

 oblique foveolato ; thorace crebre punctato ; elytris valde puncta to- 

 st riatis, subpubescentibus ; antennis ad apicem dilatatis, art. 1-5 

 testaceis, 6-11 nigro-fuscis ; pedibus testaceis. 



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



Ovate, broad, robust, rufous, subpubescent. Head short, slightly 

 depressed ; eyes large, somewhat prominent ; below the base of the 

 antennas is a transverse triangular depression ; immediately above 

 the antennae is an obsolete, obliquely transverse fovea, in the form of 

 the letter V ; surface thickly punctured. Thorax transverse ; the
