P. oyliiidrionin Kby., Fauna Bor. Am. TV., p. 113; pi. 7, fig. Z: angularis, 

 Mann., Bull. Mosc.,18.j;?, III., p. 216. — Form oblong fyTal,piceou9, shining, thorax 

 densely punctured, elytra less densely punctured, siirfnce sparsely clothed with 

 greyish-white recumbent pubescence, very easily remored. Length .1.3 — .16 

 inch ; 3i — 4 mm. 



Male. — Club of antennas longer than the funicle, termimal jioint longer than 

 the other two together and pointed at tip. 



There is a duplicate of Kirby's type before me. The elj'tra are 

 piceous, but near the posterior third luay be seen the eridences of a 

 paler transverse band. 



To this species I refer certain female specimens brougTft by Mr- 

 Crotch from the Sierra Nevada 3Iountains of California, whieb vary 

 somewhat in appearance. 



Specimen a, uniformly piceous, pubescence normal, slightly denser 

 at the sides of the thorax l^ainjularis, Mann.) 



Specimen h, similar to a, but with the pubescence adhering more 

 closely and forming a very indistinct sinuous band at basal and apical 

 third. 



Specimen c, elytra with a sinuous transverse rufo-piceous band at 

 apical and basal third to which the pubescence is very closely adherent 

 causing the elytra to be conspicuously marked. 



The distribution of the species is very wide, from Sitkha (Mann.), 

 Saskatchewan (Kirby), Lake Tahoe and Tejoti, Cal. (Crotch), Oregon 

 (Horn). 



P. I'alsHin, n. sp. 



This species resembles exactly in their form and vestiture those 

 described as variety c, above. The only differences are found in the 

 structure of the antennal club. 



Male. — Club of antennje slightly longer than the funicle, first joint extremely 

 short but nearly as wide as the second, terminal joint more than twice as long 

 as the two following together and pointed at tip. 



Female. — Club not longer than the funicle, first joint much shorter than the 

 second, terminal joint slightly longer thau the first two united and but little 

 longer than wide, oval at tip. 



The pubescence of the elytra is decidedly bi-colored, being composed of 

 pale-brownish and greyish-white hairs intermixed, the former forming narrow 

 transverse bands in front of the rufous bands of the elytra. Length .14 inch : 

 ?A mm. 



Occurs at Tejon and Santa Barbara, Cal., (Crotch), 



P. variogatiiin, n. sp. — Oblong oval, piceous or piceo-rufous, elytra with 

 two sinuous transverse bands of rufous with dense white pubescence. Head 

 and thorax densely punctured, covered witii intermixed pale-brown and white 

 hairs. Elytra oblong oval, sides sub-parallel, surface less densely punctured 

 than the thorax, color piceous with a sinuous rufous band at basal, and another 

 at apical third, rather densely covered with white pubescence, the remainder
