pronoto lateribus punctato, stria marginali integra ; elytris striis 

 dorsalibus 1-3 integris, 4-5 apicalibus, suturali obliqua basi 

 abbreviata ; prosterno baud striate ; mesosterno bistriato ; tibiis 

 anticis 4-5-dentatis.

Orbicular, somewhat convex, black and shining, surface 

 above finely punctulate ; the head is similar in form and 

 sculpture to that of P. A-punctuIus, Mars,, but the epistoma 

 and mandibles are longer; the thorax is transverse, more 

 than twice as broad as long, marginal stria fine and com- 

 plete, the lateral border is distinctly punctured, scutellar 

 puncture well-marked, basal edge irregularly punctured ; the 

 elytra, striaj, subhumeral absent, inner hu'neral very fine 

 and oblique, dorsal 1-3 strong and complete, 4-5 apical, 

 coequal, and not quite reaching the middle, sutural shortened 

 anteriorly for about a quarter of the elytral length, somewhat 

 oblique and gradually becoming closer to the suture towards 

 the apex ; the propygidium is punctured like the thoracic 

 border and is faintly impressed on either side behind ; the 

 pygidium, the basal half is punctured and the apical half 

 is smooth ; the prosternum is without striai and widens out 

 very sharply at the base ; the mesosternum, anterior stria 

 marginal and parallel to the edge, second stria transversely 

 arched and it is clearly anterior to the meso-metasternal 

 suture, and it continues laterally (irregularly crenulate) to 

 the base of the metasternura ; the anterior tibiae are 4-5- 

 dentate. 



The above belongs to the same section of the genus as 

 P. 4:-punctuluSy Mars., and others, but its stature and rela- 

 tively greater breadth render it conspicuously different.

Oval, slightly convex, black and shining ; the head with 

 the clypeus and mandibles densely but not very coarsely 

 punctured, stria complete, the median sulcus similar but 

 wider than that figured for 0. angulatus, Mars. (Mon. 1853,
