bear a deep impression just behind the shoulder, the edge at 

 that spot being strongly reflexed. The pronotum is rather 

 less strongly punctured, the metasternum is not rugose at the 

 sides, the pygidium is shining, and the front tibiae are more 

 sharply toothed.

Bab. North Borneo. 



The unique type specimen is a female in the collection of 

 M. Rene Oberthur, who acquired it from Dr. D. Sharp. The 

 species is the smallest and most striking in the genus. The 

 whole upper surface has a silky bloom, the prothorax has the 

 lateral margins orange-coloured (almost interrupted, however, 

 in the middle), and the elytra are orange, with two black 

 stripes running parallel from each shoulder to the apical 

 angles. The anterior part of the outer edge and the re- 

 mainder of the body are black. There is an angular dilatation 

 of the elytral margin behind the middle, as in the female 

 P. malayensis.
