tinctly smaller than in related species, the front being nearly equal in width to 

 twice their vertical diameter, and about equal to the third and fourth antennal 

 joints united in the. male. Length lf-2i mm. 



Southern California (Kaweah, Pomona, Pasadena) ; Arizona 

 (Hot Springs and Williams). 



The smallest species of the group, and nearly always at once 

 recognizable by its dark color. The Arizona specimens are not 

 quite typical, but are best placed here for the present. 



26. P. paulonotatus Pic. — Moderately elongate, parallel, uniformly red- 

 dish brown throughout, or with the median parts of the elytra slightly darker. 

 Antennae ( % ) a little shorter than the length of the body, subserrate, tenth joint 

 slightly less than three times as long as wide. Eyes distinctly more prominent 

 than the sides of the prothorax, the front nearly one-half wider than their ver- 

 tical diameter and very obviously wider than the combined lengths of the sec- 

 ond and third joints of the antennae. Head and prothorax granulate and hirsute 

 as usual, the hairs yellowish. Elytra moderately strongly punctate-striate, the 

 intervals a little wider than the punctures, each with a series of yellowish or 

 brownish yellow erect hairs, not varying much in length, the longest nearly equal 

 in length to the distance from the suture to the middle of the third interval ; 

 st rial setae somewhat shorter and more inclined; at basal and apical fourths a 

 narrow transverse fascia of white recumbent hairs, the anterior fascia reaching 

 nearly to the suture, the posterior one more lateral ; a short transverse subsutural 

 spot behind the middle. Metasteruum and abdomen polished, the former with 

 a few coarse, very shallow puncture? at base and side, the latter with fine and 

 still sparser similar punctures. Length 2.2-3 mm. 



Texas (Belfrage), Lower California (Sierra El Taste and San 

 Jose del Cabo). The type which M. Pic has very kindly sent me 

 for examination is identical with the Belfrage specimens in the 

 National Museum, and is probably from the same source. The 

 Lower Calfornia specimens have the erect hairs of the elytral inter- 

 vals relatively a little longer and the transverse fasciae better devel- 

 oped, but I think they are identical. All specimens seen are males. 

 A female from Pueblo, Colorado, in the National Museum collection 

 has much longer hairy vestiture and is less parallel in form ; it 

 should perhaps be referred here. 



27. P. Feminalis n. sp. — Uniformly pale red-brown ; erect hairs varying in 

 color from yellowish white to pale brown, the recumbent hairs yellowish white. 

 Head granulate and pilose; eyes moderate, very little larger in the male, separ- 

 ated on the front by about one and one-half times their vertical diameter; an- 

 tennae as long as the body in the male, outer joints fully three times as long as 

 wide; somewhat shorter than the body in the female, the joints a little less elon- 

 gate. Prothorax granulose and confusedly pilose, with longer curved hairs at 

 the front margin; disk faintly tuberculate at sides, not prominent at the con-
