NORTH AMERICAN BUPRESTID BEETLES 255 



near the middle, the inner tooth broad, much shorter than outer one, 

 and not turned inward. Genitalia not examined. 



Length, 5.75 mm. ; width, 1.5 mm. 



Female. — Not seen, but according to the original description differs 

 from the male in having a crescentic, transverse depression in addi- 

 tion to the longitudinal depression on front of head, pubescence on 

 presternum shorter and more recumbent, and the first abdominal 

 segment convex at middle. 



Redescribed from the male paratype in the collection of Dr. 

 Edwin C. Van Dyke, in the California Academy of Sciences at San 

 Francisco. 



Type locality. — Mariposa County, Calif. (Type in California, 

 Academy of Sciences. Not seen.) 



Distribution. — Mariposa County (type locality), June 12, 1914 

 (F. W. Nunenmacher) . 



Host. — Unknown. 



From the single male examined this species seems to be closely 

 allied to abditus Horn, described from western Nevada. It differs, 

 however, from that species in having the front of the head broadly 

 and rather deeply depressed, the marginal and submarginal carinae 

 separated from each other for their entire length, and with a feebly 

 indicated pubescent vitta on each elytron. It is just possible that 

 specimens will be found with the pubescent vittae more distinct, in 

 which case it might be confused with illectus Fall, but it can be sep- 

 arated from that species by having the sides of the pronotum only 

 feebly depressed, and these depressions without long pubescence.

Female. — Form moderately robust, subeylindrical, feebly flattened 

 above, and moderately shining: head brownish cupreous; pronotum 

 and elytra brownish cupreous, with the sides of pronotum and a 

 vitta on each elytron clothed with whitish pubescence; beneath

Head with the front moderately wide, feebly convex, and slightly
