specimen 



like P. angustidum

4. Pseudopentar thrum planifrons, sp. n. 



Moderately elongate, subcylindrical, shining, black, the antennae and tarsi ferruginous. Head very sparsely 

 punctate, almost unimpressed between the eyes ; rostrum very short and stout, finely punctate. Pro- 

 thorax about as long as broad, oval, feebly constricted in front, somewhat closely punctate. Elytra 

 considerably wider than the prothorax, moderately long, parallel in their basal half, coarsely seriate- 

 punctate, the punctures placed along fine, shallow striae near the suture and becoming smaller and more 

 scattered towards the sides, the sutural striae deeply impressed from a little below the base, the 

 interstices flat and obsoletely uniseriate-punctate. Beneath sparsely, finely punctate. Anterior coxae 

 subcontiguous.

One specimen. This is a true Pseudopentarthrum, following Wollaston's diagnosis, 





and nearly related to P. brevirostre, differing from that insect in the relatively narrower 

 prothorax and the more scattered seriate punctures on the elytra, those near the suture
