new Species of Histeridse. 155 



rather near together, they join anteriorly and widen out 

 gradually to the base, but the interstice is narrow; the meso- 

 sternurn is bisinuous and only moderately projecting in the 

 middle, marginal stria complete but not close to the edge, on 

 either side is an outer short bent stria, surface and that of the 

 metasternum and first abdominal segment are finely punctu- 

 late ; the anterior tibiae are 5-denticulate. 



This species may be placed near P. puncticollis, Lew., but 

 the two species are not very similar.
