EHYXCHOPHOEA. 

 Prepodes amabilis, sp. n. 



Statura P. vittati, niger, nitidus: elytris sutura vitta 

 lata longitudinali marginibusque Itete aureo-viridibus, vel 

 cvaneis, humeris magis ans^ulatim productis. 

 ' Long. 10 — 12 lin. 



Form of P. vittatus, but with the humeral angles of the 

 elvtra more prominent ; the punctuation of the elyti-a is 

 rather stronger and there is less rugosity at the apex. 

 The elvtra have the suture, a broad stripe and the mar- 

 gins bright metallic pale golden-green or pale bluish. 

 The sides of the body and of the prostemum are also 

 metallic blue. 



Var. \. Elytra without stripes; each puncture of the 

 elytra with a small green scale in the middle. 



Var. 2. Elytra with a blue sutiu-al stripe, and orange 

 dorsal and lateral stripes. 



If this species varies as much in colour as does P. vit- 

 tatus, there will be little to separate it but the more pro- 

 minent shoidders and the sti'onger punctuation. The 

 punctures on the elyti'a have each a small blue scale in 

 the middle, which does not seem to be the case in vittatus. 



The following notes on the varieties of P. vittatus will 

 be useftd : — 



1. Head, thorax and clA'tra entirely clothed with grey- 

 ish-white, or pale oreen-o-olden scales; the suture pale
