100 HYPAXTHERUS. 



4. Hypantheras Batesii. 



H. oblongo-ovatus, robustus, obsolete pubescens, rufo-ferrugineus ; 

 capite brevi, antice subproducto, inter oculos bituberculato, ad 

 basin punctato ; thorace transverso, rectangulari ; elytris robustis, 

 ante medium obsolete depresses, punctato-striatis ; antennis ro- 

 bustis, flavis, art. 6-8 incrassatis et nigris ; pedibus rufo-jiavis.

Oblong-ovate, robust, obsoletely pubescent, rufo-ferrugineous. 

 Head short, transverse, slightly produced in front ; below the base of 

 the antennse is a transverse triangular plane depression ; above the 

 base are two short tubercular elevations (not produced longitudinally, 

 as in H. ambiguus) ; at the base of the head deeply punctate (not 

 granulated, as in H. ambiguus) ; the eyes are lateral and globose, 

 situated nearly at the base of the head : in colour the apex is flavous, 

 and the transverse depression below the antennse fuscous (in H. am- 

 biguus, the anterior part of the head is uniformly rufo-ferrugineous) ; 

 the base is ferrugineous, medially fuscous. Thorax transverse, rect- 

 angular; the anterior angles depressed and subacute; the sides 

 parallel and evenly marginate ; the surface equate, thickly punctate, 

 and obsoletely pubescent (less distinctly so than in H. ambiguus), 

 rufo-ferrugineous, medially broadly piceous. Scutellum triangular, 

 fuscous. Elytra broad, robust, antemedially transversely depressed, 

 rufo-ferrugineous (not fuscous, as in H. ambiguus) ; finely pubescent, 

 punctate-striate, the striae being deep, and the punctures obsolete. 

 Antennas robust, medially dilated, flavous, the sixth to the eighth 

 joints being incrassated and black. Legs robust, subpubescent, rufo- 

 flavous. 



The above description indicates the several points of difference 

 between this species and H. ambiguus, to which it is very closely 

 allied. H. Batesii may be separated not only by the colour and 

 striation of the elytra, and the colour of the thorax, but by the form 

 of the tubercular markings about the base of the antennae. 



Taken by Mr. Bates in the district of the River Amazon, and in 

 that gentleman's collection.

 formibus, robustis ; pedibus posticis brevibus.
