in front of the hind angles which are subacute, the lateral margin extremely 

 feeble and slightly inferior ; disc convex, a feeble depression of the median line 

 posteriorly, the surface with an inconspicuous intermixed punctuation, somewhat 

 rugose at the sides ; elytra striate, striaj iiunctate, intervals flat and equal 'J, , or 

 alternately slightly narrower and more convex 9 » the surface inconspicuously 

 finely punctate, with somewhat coarser punctures intermixed ; body beneath very 

 finely and moderately densely punctate, with slightly larger punctures inter- 

 mixed, which are larger on the sides of prothorax ; legs similar in color to the 

 surface. Length .42 - .80 inch ; 10.5-20 mm. 



In addition to the fine pubescence there are s])arsely placed, serai- 

 erect, short hairs. The males are known by their usually darker 

 color, more slender form, antenna? longer, and the elytral intervals 

 equal. 



Occurs from Pennsylvania to Florida. 



P. Wittifisi Lee. — Form oblong, parallel, rather robust, piceous or brownish, 

 clothed with fine yellowish cinereous sericeous pubescence; antennae nearly as 

 long as half the body % , a little shorter 9 ; head coarsely, sparsely punctate, 

 with fine punctures between, front vaguely longitudinally impressed, supra-an- 

 tennal ridges nearly transverse, united across the front ; thorax much wider than 

 long, narrower in front, sides strongly arcuate, slightly sinuate in front of the 

 hind angles which are subacute, lateral margin distinct from the hind angles 

 two-thirds to apex ; disc very convex, median line slightly impressed posteriorly, 

 surface not densely punctate, the intermediate finer punctuation very indistinct ; 

 elytra very little wider at base than the thorax, parallel, narrower at apical third, 

 striate, strife indistinctly punctate, the intervals slightly convex equal, sparsely 

 punctate, the finer intermediate punctuation almost obsolete ; body beneath 

 densely finely punctured with coarser punctures sparsely placed, which are 

 coarser on the prosternum, the pubescence fine, silken and moderately dense ; 

 legs similar in color to the body. Length .62 - .80 inch ; 15.5 - 20 mm. 



This species greatly resembles muclda; it has, however, a more 

 robust facies, the pubescence is closer and more silken. The most 

 obvious structural differences are those given in the table. 



Occurs in the middle reirion of California.
