AMERICAN COLKOPTERA. 119 



All specimens seen, except one from Oregon (collected by Koe- 

 bele), are from the Middle California Coast Region (San Francisco 

 and Alameda Counties, and Los Gatos), where it appears to be as 

 common as agnatus is in Southern California. 



11. I*, longivestis n. sp. — Brown, moderately elongate. Head densely, 

 finely granulate, pilose ; eyes not strongly convex and scarcely more prominent 

 than the sides of the prothorax ; front twice as wide as the vertical diameter of 

 the eye; antennae four-fifths as long as the body, joints 3-10 subequal in length, 

 about twice as long as wide, each a little widened apical ly; eleventh one-third 

 longer than the tenth. Prothorax of the usual form, closely granulate and 

 densely confusedly pilose; the hairs of unequal lengths, varying from whitish to 

 pale brown ; at the anterior margin numerous, very long, fine, posteriorly curved 

 hairs. Elytra oblong, humeri small but distinct, sides feebly arcuate and nearly 

 parallel in basal two-thirds; strial punctures quite coarse, the interspaces subequal 

 in width to the strife; setae of the strial punctures straight, about twice as long 

 as the interstrial width, and inclined at an angle of 45°; each interspace with a 

 row of setae of equal length to those of the striae, but more erect, these alterna- 

 ting on alternate intervals, with excessively long, fine, erect curved hairs. 

 Throughout the surface, except the middle portion of each elytron, are scattered 

 subrecumbent, whitish, subsquamiform hairs, but these are mainly condensed in 

 the humeral region and in a feebly defined interrupted transverse fascia at the 

 apical fourth. Sculpture and vestiture beneath as usual ; fourth ventral segment 

 about half the length of the third and two-thirds as long as the fifth. Legs 

 moderate; first joint of hind tarsus not longer than the next two united. Length 

 2i mm. 



Described from a single example, probably a female, taken at Ft. 

 Yuma, Arizona, by Mr. Hubbard, and now in the National Museum 

 collection. 



1'2. P. californicus Pic. — Oblong, moderately robust, blackish brown ; head, 

 prothorax, legs and antennae dark rufous. Antennae nearly as long as the body, 

 the outer joints about four times as long as wide in the male; shorter, stouter, 

 the outer joints scarcely more than twice as long as wide in the female. Eyes 

 moderate, separated on the front by about one and two-thirds times their vertical 

 diameter in the male, a little smaller in the female, the front relatively wider. 

 Head behind the antennae densely clothed with small whitish scales and short 

 intermixed fulvous setae. Prothorax densely granulate, moderately constricted, 

 tuberculate at sides of the disk, rather sparsely clothed with short inconspicuous 

 hairs, which are much inclined, except on the lateral tubercles. Elytra parallel, 

 strial punctures strong, intervals a little wider than the striae; setae of strial 

 punctures minute, those of the intervals blackish, very short and almost recum- 

 bent; posthumeral and subapical transverse patches of white scales very con- 

 spicuous; scutellum densely clothed with pale hairs. Beneath clothed with re- 

 cumbent, coarse, cinereous or fulvo-cinereous hair. Legs rather stout, more slen- 

 der in the male. Length 4-5 mm.
