The general form of this species is not described by Gray nor Burmeister, but they 

 note the convex, alternately punctured and smooth, interstices of the elytra, and golden- 

 green tarsi. Boucard, who states that he possesses Gray's type-specimen, describes its 

 form as " oblongo-ovata," and decides, after careful examination of authentic examples 

 of both species with the aid of Mr. C. O. Waterhouse, that it is specifically distinct 

 from the following, with which it was united by Burmeister.

Hah. Mexico x (Salle, ex coll. Sturm). 



There are two examples of this species in the Salle collection, named by Sturm with 

 the synonym on the label in his handwriting "P. auripes, Gray." Sturm therefore 

 considered his species to be the same as the earlier described P. auripes. The insect is 

 33 millim. long, of elongate oblong shape, even in the female, and wholly clear apple- 

 green, slightly metallic on the underside, epipleurae, and legs, the tarsi more brilliant 

 metallic green. The elytra are irregularly punctured on the alternate interstices 

 (second, fourth, sixth, and eighth) and minutely punctulated throughout ; the head and 

 thorax are somewhat closely punctured, with the interstices minutely punctulated ; and 

 the pygidium punctulate-strigulose. The sternal process is very short, slightly projecting 

 and conical. 



The type-specimen of P. Iceta (Sturm) is contained in the Salle collection; it is 

 evidently a small and somewhat deformed example of P. psittacina. According to the 

 label, Sturm regarded it as synonymous with P. amalia, Burm., and as such it has 

 been classed by subsequent authors. Sturm gave the locality as " Brazil," Burmeister as 

 "Valparaiso"; but the insect is most certainly Mexican. It is to be remarked that 

 Burmeister placed his P. amalia in a different section (sternal process very short) of the 

 genus from P. auripes (sternal process projecting as a strong cone beyond the middle 

 coxae). In both of Sturm's species, P. psittacina and P. Iceta, the sternal process is of 

 the same length, very short, and only slightly projecting.
