Bab. Mexico, Vera Cruz (ZT. H. Smith). 



A smaller species than P. mexicanus, from which it differs 

 in having the flagellum of the antennne entirely testaceous 

 beneath, the body uniformly coloured (wanting the green and 

 coppery reflections), the scutellum larger and more pointed, 

 and the legs darker in colour.

 almost bare; the flagellum covered with a pale pile, testa- 

 ceous beneath, black above. Head black, finely punctured 

 above, and with a close short pile; the face shining; the 

 central part broadly triangularly dilated, the base of the 

 triangle raised and separated by a furrow from tlie rest; the 

 tips of the mandibles testaceous. The thorax above is 

 closely punctured, the lateral lobes of the mesonotura only 

 slightly punctured and more shining than the rest. The 

 scutellum is large, coarsely punctured ; the apex margined, 

 projecting a little over the apex of the median segment. The 

 propleuraj with large widely separated punctures in front; 

 the mesopleurje excavated in front, shining, the edges

Fam. Trigonalidae. 

 Trigonalys, Westw. 



It is evident that this genus will prove to be numerously 

 represented in Central America. 1 have called the family 

 TrigonalidjE ; but Foerstcr, it may be remarked, has named 

 it Diplomorpha, distinguishing it from his Eatricliocera 

 (^= Stephanus) by the scape of the autennaj not being filiform
