each side of the norle is a short laterally pointed acute tooth or

^ . Very similar to P. mayri and P. proxima. Kesembles the 

 former in having the thorax narrower posteriorly than in front, 

 and the latter in wanting the transverse carina bordering the 

 basal portion ot" the metanotum, in the closely a|iproximate 

 antennal carina), and the bimucronate lateral spines on the pedicel. 

 Differs from both in having greyish, not golden pubescence very 

 sparse, not hiding the sculpture ; this gives it quite a different 

 appearance.

I am not quite certain whether I have identified this species 

 correctly. J. ha\e not met with it further south in Burma than 

 the Buby Mines district.

^ . Closely resembles P. mayri, being black and co> ered with 

 similar dense golden shining pubescence, which hides the sculp- 

 ture ; but besides the bimucronate lateral spines on the pedicel, 

 this species is shorter than P. mayri, with a proportionately wider 

 thorax posteriorly, and with the antennal carinas very much closer 

 together. 



$ . Resembles $ of P. mayri, but the mesouotum and scutellum 

 are still more gibbous and raised than in that sjiecies
