 the sides strongly rounded in front and contracted abruptly

 before which there is a more or less 

 distinct impression ; sides set with short 

 setae; upper surface rather shining, 

 sculpture fine and variable but some- 

 times distinct ; elytra rather long, ob-

Var. unicolor, Westw. 



Differs from the type-form in being of a unicolorous brownish 

 castaneous colour, and in having an abbreviated transverse stria 

 across the pronotum.

According to Westwood P. unicolor differs from P. dentkomis in 

 its uniform colour, in having the front of the head apparently 

 rounded, in the suddenly coarctate base of the pronotum (this, 

 however, is a strongly marked character of P. dentkomis), and 

 in the short transverse median stria of the same ; the characters 

 are not, however, sufficiently marked to separate it specifically.

Besembling P. dentkomis, but smaller and relatively broader, 

 rufo-castaneous, with a longitudinal dark stripe on each elytron, 

 which stripes are united in the middle by a transverse band. The 

 club of the antennae is larger and broader than in P. dentkomis, 

 scarcely longer than broad, and with much longer setae ; pronotum 

 shorter, twice as broad as long, but still cordiform ; the elytra at 

 the sides are furnished with long setae, which are much 'longer 

 than in P. dentkomis.
