Closely resembles P. (■oiijnucta, G. & P. (Westwood, Trans. 

 Ent. Soc. Lond. 1874. p. 478. Tab. VIII. fig. 5) in general 

 appearance, but is more convex and shining, the head much 

 narrower, the elytra have only two white spots on each, the red 

 marking is brighter and of a different form, and the pygidium 

 of the female is not tuberculate, it is also less punctured above, 

 and the sculpture of the elytra is different. 



The only specimens I have seen of this elegant species I 

 obtained, with many other fine Cetovikhv, from the rich collection 

 recently made by Mr. Crossley.
