114 H. C. FALL. 



Last ventral of male without distinct apical tubercle; strial punctures 

 finer 14. 



14. Size larger (2|-3i mm.), eyes of male larger 24. f'allax. 



Size smaller vl}-2i mm.), eyes of male smaller; the color darker, the base and 



apex of the elytra usually scarcely paler than the central area. 



25. vegrandis. 



15. Pale hairs nearly evenly but not densely distributed over the basal and api- 



cal parts of the elytra; interspaces about twice the width of the strial 



punctures 27. feminalis. 



Pale hairs of elytra in great part confined to narrow subbasal and subapical 

 transverse bauds; interspaces of the elytra not much wider than the 

 strial punctures 26. paiilonotatiis. 



1. P. brunnetlS Duft. — Similar to far, except in the following particulars: 

 The color is more often rufo testaceous or pale brown in both sexes, but varies to 

 dark brown in the male and piceous brown in the female. In the male the eyes 

 are slightly more remote on the front, being separated by a distance which evi- 

 dently exceeds the united length of the first and second antennal joints; the 

 median line of the pronotal disk not or scarcely prominent behind ; elytra 

 entirely without recumbent scales ; first joint of hind tarsi distinctly shorter than 

 the three following united. In the. female the elytra are a little more broadly 

 oval, the erect hairs not so stout and distinctly longer, being about twice as long 

 as the width of the interspaces ; there are also very slightly longer hairs on alter- 

 nate interspaces; the humeral region alone is clothed rather inconspicuously 

 with yellowish recumbent subsquamiform hairs, but these are inconstant in de- 

 velopment or else easily lost, for many specimens show scarcely a trace of them. 

 In both sexes the head behind the antemne is polished and quite strongly punc- 

 tate, a character which separates brunneus from all its allies when the vestiture 

 permits of its verification. In the male the hairs of the elytra are slightly 

 longer and more bristling than in far, but the difference is less marked than in 

 the other sex. 



Like fur, this is a nearly cosmopolitan species. It is known to 

 me from the following localities in our fauna: New York, New Jer- 

 sey, District of Columbia, North Carolina, Georgia, Ohio, Wiscon- 

 sin, Indiana, Illinois, Missouri, Iowa, Kansas, New Mexico (Albu- 

 querque. 



2. P. fur Linn. — Male. — Color varying from rufo testaceous to pale brown ; 

 head alutaceous, not shining, vertex finely, sparsely punctulate, rather densely 

 clothed with recumbent yellowish hair; eyes large, separated on the front by a 

 distance distinctly greater than their own vertical diameter, and subequal to the 

 united length of the first and second antennal joints; antennae subequal in length 

 to the entire body; first joint stoutest, a little arcuate; second much narrower 

 and subquadrate; third to tenth elongate, parallel, differing little in length, the 

 third about twice as long as wide, the tenth four times as long as wide ; eleventh 

 oue-fourth longer than the tenth, slightly arcuate apically, the apex pointed. 

 Thorax a little narrower than the head across the eyes, nearly as wide as long, 

 sides parallel in front, strongly constricted posteriorly; surface sparsely granu-
