This species is very closely allied to the preceding, so 

 that it is only necessary to point out the characters dis- 

 tinofuishino^ it therefrom. The antennas have the first five 

 joints pale yellow, 7 — 10 nearly black, the 11th again 

 pale. The punctures on the thorax are coarser and rather 

 more numerous in /"*. virf/incus ; the upper side of the 

 hind body is distinctly though finely punctured, this being 

 especially evident on the 3rd and 4tli segments. The 

 hind body is also narrowed and pointed at the extremity, 

 but this is ]irobably a character ]ieculiar to the female. I 

 have no doubt the discovery of the male will prove this to 

 be a good and distinct species.

Ohs. — Though this species greatly resembles P. Icetus, 

 P. ventralis and P. Traili, I feel no doubt it will prove 

 distinct from all of them : the female is readily distin- 

 guished by its sexual characters from the same sex of 

 1*. Icetus ; the females of the other two species being im- 

 known to me, I can of course make no comparison with 

 them.

Antennna slender and rather long, yellow, with the 7th 

 and 8th joints infuscate ; 3rd joint not cpiite twice the length 

 of the 2nd; 4th not quite so long as 2nd; 11th joint 

 rounded at the extremity. Palpi pale yellow, mandibles 

 pitchy. Head about as broad as the thorax, above of an 

 obscure-greenish colour, and not very shining ; all the disc 

 free fi'om ])iuictures, and a little convex ; the sides coarsely 

 punctuivd ; a quadrate sjjaee behind the labrum depressed, 

 and Avith some very coarse but not well-defined ])unctures. 

 Thorax black and shining, narrower than the elytra, 

 transversely convex, its length hardly greater than its
