 antennarum articulis basalibus 3 subtus testaceis ; ociilis 

 modicis ; prothorace angiiste elongato ; elytris basin versus 

 angustatis quam prothorax subbrevioribus, sparsim punc-

 In general build resembles P. australis, Guer., but apterous and 

 with much shorter elytra and the elytra (and still more the 

 abdomen) more sparsely punctured. Coloured like a very dark 

 example of P. critenticollis, Germ., but differing from that species 

 as from australis in respect of its elytra and abdomen, and also in 

 its much narrower prothorax less rounded laterally, its antennae 

 much less dilated towards the apex, &c. From P. Meyricki, 

 Blackb., the present in.sect differs by its smaller size and much 

 more parallel and slender Vjuild, its much smaller and more sparsely 

 punctured elytra, narrower prothorax, evidently larger eyes, &c.

A. orbiculato, Gyll., valde atfinis ; differt colore elytrorum sub- 

 senescenti, humeris Isete pallide testaceis, his valde callosis, 

 antennis pauUo magis elongatis, elytrorum striis magis fortiter 

 impressis, harum interstitiis manifesto convexis.

 The general colour is a shining pitchy, inclined towards reddish, 

 more particularly on the elytra, which have a slightly metallic 

 appearance. The humeral calli are extremely prominent and of 

 a pale testaceous colour, the legs and antennae (except the club of 

 the latter which is darker) reddish-testaceous. The antennae are 

 of 10 joints, the basal large and pyriform, 2nd much smaller and 

 .subglobulous, 3rd slender and as long as the 1st, 4th nearly half 

 as long as 3rd, 5-7 very short, 8-10 forming an elongate club as 

 long as 2-7. The elytra are rather strongly punctulate-striate
