deeper and the sculpture a little sharper; the elytra are wider 

 with the impressions less evident and almost absent ; the sides of 

 all the sterna are smooth ; the colour of the upper surface is a 

 brighter copper, more shiny, and the whole margin of the elytra 

 from the shoulders to the posterior white spot is bright cyaneous ; 

 in the single female specimen described by Dr. Horn the whitish 

 spots are arranged as follows : one, very small, at the shoulder, 

 another near the margin at middle, a third situated at the side of 

 .and behind this, at a much greater distance than is the case with 

 the third spot in P. exornata, and a fourth near margin at apex ; 

 the third spot is at about an equal distance from the second and 

 fourth and forms with them an equilateral triangle ; according to 

 Dr. Horn there is no humeral spot in the female in P. exornata, 

 but there is a specimen in the Calcutta Museum in which a very 

 small one is present. The palpi (with the exception of the last 

 joint) and the trochanters are yellow ; the posterior femora are 

 entirely without hairs.

Mr. H. E. Andre wes has lent me a specimen of this insect 

 labelled " Goktaik, vi. 10," taken by Mr. H. Leslie Andrewes and 

 named by Dr. Horn ; the apical white spots are very conspicuous, 

 but the only other marking is a very small white spot just behind 

 the middle of the left elytron.

Allied to P. exornata, Schm.-Groeb., but with the labrum shorter, 

 the forehead and pronotum broader, and the sides of the latter 

 more rounded ; the elytra are less elongate with the apices more 

 .obliquely truncate ; the sculpture is slightly closer, and the 

 impressions are more strongly marked ; the punctures near the 

 suture in the middle are transversely confluent ; the marginal 

 spot behind the middle is very much smaller and scarcely visible, 

 the discoidal one being larger and more approximate ; the upper 

 surface is coppery and less shining. 



Length 10^-11 millim.

Dr. Horn says that this species possesses two yellowish spots in 

 the centre of the elytra like P. exornata, P. schmidt-goebeli, and 

 P. heteromalla, but these are more approximate to one another and 

 the lateral one is much smaller than the one on the disc. The 

 species is more robust and shorter than P. exornata, especially as 

 regards the elytra, which are also more oval. 



I have before me the specimen taken by Mr. H. L. Andrewes ; 

 the lateral spot is quite wanting and the other spot behind the
