quadrata humerali, fascia mediana alteraque apicali nigris ; an- 

 tennis elongatis, apice gradatim incrassatis, nigris, flavo aiinulatis ; 

 thorace cylindrico, convexo, crebre reticulato-punetato ; elytris 

 vix abbreviatis, basi excepta angustatis parallelis, apice oblique 

 truncatis, dense reticulato-punctatis. Long. 4| lin. c? • 



Prov. Parana, Brazil {coll. W. W. Saunders and H. W. 

 Bates). 



Linear, thorax and elytra closely covered with round punc- 

 tures forming narrow reticulated interstices. Clear pale yellow, 

 with an irregular spot on the disk of the thorax, a belt across 

 the middle and apex of the elytra, and a square spot on the 

 shoulder black. The antemife (male) are nearly as long as 

 the body and considerably thickened towards the apex, the 

 third to fifth joints are linear ; the colour is black, with the 

 base of fourth to tenth joints and first to fourth joints beneath 

 pale testaceous. Beneath there is a broad stripe on each 

 side of the metasternum and across the abdomen, black. The 

 legs have a streak on the upperside of the femoral clav£e, the 

 apex of the tibise and the tarsi black ; the hind legs are not elon- 

 gated ; all the femora are clavate, the anterior and middle pair 

 more abruptly so than the posterior. The elytra are moderately 

 narrowed from a little behind the base, and are thence parallel 

 to the apex ; they are not dehiscent at the suture ; and the ex- 

 ternal angle of the apical truncature has a longish spine. 



A variety occurs in which the middle and apical black fasciae 

 of the elytra and the humeral spots are united, and the head 

 and whole apical half of the abdomen is black.

I have nothing to add to the definition of this genus given 

 by Lacordaire, except that I think it better to exclude every 

 species which has not a vitreous surface to the elytra. This
