fere recta; pronoto stria iutegra ; elytris striis 1-3 integris, 

 4 valde abbreviata, 5 dimidiata, suturali brevissima vel obsoleta ; 

 pygidio margine auguste lsevi haud conspicue elevato. 

 L. 5-5 £ mill. 



Oblong-oval, rather depressed, black and shining ; the 

 head impressed anteriorly, transverse stria feebly sinuous, 

 labrum transverse and narrow ; the thorax widest at the base, 

 anterior angles moderately depressed, marginal stria com- 

 plete; the elytra, strise 1-3 complete, 4 apical, short, and 

 sometimes broken, 5 apical and dimidiate, sutural short, 

 much abbreviated apically, and not reaching the middle of 

 the elytron ; the piopygidium punctured, the punctures vary in 

 size and are not closely set ; the pygidium, the punctures are 

 larger, nearly equal in size, and much more closely and 

 evenly set, the outer margin is smooth but scarcely elevated ; 

 the piosternum, anterior lobe striate, stria arched and only 

 marginal anteriorly ; the mesosternum, anteriorly rather 

 widely but not deeply emarginate, stria complete ; the 

 anterior tibiaj rather strongly 4-dentate. 



Differs chiefly from P. suturalis, Lew., in its labrum being 

 much more transverse, in its shorter and less defined sutural 

 stria, and in the posterior margin of the pygidium being 

 smooth and scarcely elevated.

This species is extremely like P. abruptus, Er., the elytral 

 strige are exactly similar, viz. 1 and 2 complete, 3 interrupted 

 near the middle, but the thorax is rather more transverse, the 

 lateral outline rather less parallel, and there is a conspicuous 

 fovea before the scutellum. The piopygidium is smooth, with 

 a shallow impression on either side near the posterior edge, in 

 which there are a few small punctures, and the pygidium on 

 either side near its base has a small cluster of punctures, but 

 it is otherwise smooth and flat. In P. enodis the stria of the 

 prosternal anterior lobe is marginal ; in P. abruptus it is 

 an independent arched stria not following the margin; in 

 P. enodis the mesosternum has a slightly wider emargination 

 and the marginal stria is more marked than in P. abruptus.
