as long as the third and fourth joints combined, third joint 

 a little broader at the apex I ban long. Ocelli in a broad 

 triangle, the posterior pair fully half as far again from each 

 other as from the eyes. Pronotum as broad as the meso- 

 notum, smooth and shining, the mesonotum shining, with 

 large and rather sparse punctures ; scutellum and post- 

 scutellum shining, the former with a few small punctures. 

 Tergites shining, rather closely covered with large and very 

 deep punctures, on the fourth tergite the punctures become 

 sparser and shallow at the apex, those on the fifth tergite 

 are small and scattered, sixth tergite almost smooth ; 

 sternites shallowly and sparsely punctured. Median seg- 

 ment finely and closely punctured ; the basal triangular 

 area large, covering almost all the dorsal surface, smooth 

 and shining with a well-marked median sulcus and without 

 marginal carinse. Cubitus of the hind wing interstitial 

 with the transverse median nervure, the fore wings with a 

 small fuscous cloud at the extreme apex.

Easily distinguished by the very coarse puncturation of 

 the tergites. Nearly allied to the group of P. venustus, 

 Rossi.

? . Clypeus rounded at the apex, shining, shallowly and 

 very sparsely punctured; front very finely and closely 

 longitudinally rugulose, vertex punctured, the punctures 

 more or less confluent transversely ; posterior ocelli as far 

 from each other as from the eyes. Antennae very stout ; 

 second joint of the flagellum rapidly broadened from the 

 base, almost as broad at the apex as long, scarcely longer 

 than the third joint ; the third to tenth joints broader than 

 long. Mesonotum and mesopleurae closely and rather 

 coarsely punctured, scutellum and postscutellnm more 

 closely and finely punctured ; median segment irregularly 

 rugulose on the sides and on the apical slope; the triangular 

 dorsal area rugose, margined by distinct grooves. The two
