Hab. — Sumatra (E. C. Buxton, Esq.). Brit. Mus. 



Very near to hrevicollis, but the formation of the fore- 

 head is different, the joints of the antennas are more 

 elongate, and the elytra are of a much deeper red. 



Pi/ropterus sculpturatus, sp. n. 



Nigro-piceus, opacus, subpubescens ; ancennis crassis; 

 thorace parvo, antice angustiori, quinque areato ; elytris 

 rubris quadri-costatis, costis validis, interstitiis cariuis 

 validis transversis numerosis. 



Long. 3^ lin. 



Resembles Pyropterus affinis, Payk., but is relatively 

 shorter, the sculpture is much stronger and the elytra are 

 deeper red. Antennas very stout, the 2nd and 3rd joints 

 small and transverse. Thorax smaller than in affinis, the 

 max'gins more thickened, the elevated lines on the thorax 

 more pronounced and the mesial lozenge-shaped areolet is 

 much broader. Elytra relatively shorter than in affinis, 

 the sculpture is similar, but the costre are much more 

 strong, especially the transverse ones, which are also very 

 regular.
