These seem to me to be mert;ly slight colour-varieties of 

 the same species. A variety in vvliich the yellow marking.s 

 on the mosoiiotum are narrower than in the typical form 

 occurs in Ceylon.

Allied to P. pulcherrimus, Bingh., but is a larger and more 

 robust specie.^, and has the basal area of the median segment 

 much mure strongly striated.

Possibly an extreme local variety of <S'. chalybeum, but the 

 very great col< iir-differenees, espcci;dlyof the legs and wings, 

 and tlie di.^^tincily closer pumturation of the mesonotum, seem 

 .^uffieii lit to meril .sp'-citic rank. The colour of the basal an- 

 tiiihal joints in chilijbcum appears to be subject to considerable 

 variation.
