AMERICAN COLEOPTKRA. 117 



Two males only have been seen, one from Los Gatos, California, 

 the other from California without indication of precise locality. It 

 is not impossible that this may be the male of alteruatus, but I do 

 not feel warranted in placing them together without definite knowl- 

 edge of such relationship. In this and all the following species of 

 the subgenus the seta? of the strial punctures are very minute, and 

 it is worthy of note that all these species are peculiar to the Pacific 

 Coast fauna. In all the species of the Atlantic district the strial 

 setae are well developed. 



7. P. verticalis Lee. - - Fe male. — Densely clothed with ochreous recumbent 

 squamiform hairs. Head and prothorax of nearly equal width aud about one- 

 half the width of the elytra, the latter elongate, ventricose, each interspace with 

 a row of short, erect, acuminate, pale bristles, and alternate interspaces with 

 more widely spaced, longer, pale erect hairs. Length ".17 inch." 



California (Ft. Tejon). 



The unique female type in the LeConte collection, taken forty-five 

 years ago, has never been duplicated, nor has a mate as yet been 

 found for it. Verticalis resembles quite closely gandolphei, the only 

 other species of the subgenus in our fauna which approaches it in 

 density of vestiture, and I at first believed them to be identical. A 

 recent comparison of females of the latter with the LeConte type 

 shows that the vestiture in gandolphei is somewhat less dense and 

 less evenly disposed, and the elytral bristles are more inclined and 

 distinctly recurved ; differences which are without much doubt 

 specific in nature. 



8. I*, gandolphei Pic. — Form almost precisely as in fur. Eyes of male 

 large and prominent, the front not wider than the combined length of the first 

 two antenual joints; autenuse ( % ) exceeding the entire leugth of the body ; me- 

 dian line of pronotal disk not prominent behind. Elytra ( % ) plentifully though 

 not densely clothed throughout with coarse recumbent dirty yellow hairs, which 

 are somewhat irregularly diffused, each iuterspace with a row of short inclined 

 and recurved bristles; hairs of strial punctures very short and contained entirely 

 within the punctures. In the female the elytral vestiture is denser, and the 

 alternate interspaces bear long, fine, erect hairs. First joint of hind tarsus 

 scarcely longer than the next two united. Length 3-3.5 mm. 



California. 



This species was described from Mariposa and appears to be quite 

 local, and as yet rare in collections. Two examples in the collec- 

 -tion of Mr. Fuchs are labelled as having been taken in the vicinity 

 of San Francisco ; all others seen by me were taken by Mr. Hop-
