In colour of body and legs this variety much resembles P. virescens, especially the 

 Guatemalan form, the latter, however, is more elongate and more brilliantly relucent, 

 besides wanting the brassy-green bilobed spot on the vertex. The head, moreover, is 

 smaller in the present species, and the clypeus in the male very different, being 

 triangular, and not rounded.

This species is distinguished by its testaceous-yellow colour (clypeus concolorous) and 

 its brilliant glassy silvery-green lustre. But it varies much in outline and convexity 

 and sculpture, the elytra especially, which in the typical state are punctulate-striate 

 with convex interstices, being sometimes smooth with very fine striae and flat inter- 

 stices. In the typical form the underside of the body and pygidium are brassy-green, 

 and the legs testaceous, more or less inclining to brassy-green on the femora and tibiae. 

 In some localities varieties occur which, although not very constant, depart so much 

 from the type as to merit separate mention : — 



Var. 1. Elytra striis minime impressis interstitiisque planissimis. 



Hab. Mexico, Acapulco (Hoge), Vera Cruz (Salle). 



Var. 2. P. aurescens. Supra aurescenti-relucens ; clypeus in 3 antice plerumque aagustato, apice reflexo 

 subsinuato. (Tab. XVI. fig. 5.)
