NORTH AMERICAN BUPRESTID BEETLES 299 



process broad, the sides parallel to behind the coxal cavities, then 

 strongly narrowed to the apex, which is acute. Tibiae slender, the 

 anterior and middle pairs slightly arcuate, and armed with a short 

 tooth on innner margin at apex. Posterior tarsi slightly shorter 

 than tibiae, and the first joint as long as the following two joints 

 united. Tarsal claws similar on all feet, cleft near the middle, the 

 inner tooth broad, shorter than outer one, and not turned inward. 



Length, 6.75 mm. ; width, 1.75 mm. 



Female. — Differs from the male in having the front of head 

 uniformly reddish cupreous; first two abdominal segments more 

 finely punctured; long, erect pubescence on prosternum and median 

 part of body not quite so distinct and the tibiae all unarmed at 

 apex. 



Redescribed from the male lectotype No. 3488 (except the posterior 

 claws, which are missing on the lectotype) in the Philadelphia 

 Academy of Natural Sciences. 



Type locality. — Tehachapi, Calif. 



DISTRIBUTION 



Material examined : 



California: Los Angeles County, July (D. W. Coquillett). San Jacinto Moun- 

 tains, July 14, 1912 (P. H. Timberlake). Azusa, Los Angeles County, 



July 25, 1906 ( ). San Diego, Inyo Mountains, July 7-11, 7,000-9,000 



feet, and Tehachapi (H. F. Wickham). Pasadena, June-July (H. C. 

 Fall). Chaniberlin (1926) records it from Utah and Arizona, but no 

 specimens have been examined from these States. 



Variations. — The coloration is rather constant, except that in a 

 few examples the pronotum is more brownish than the elytra. The 

 pubescence on the sides of the pronotum is sometimes more or less 

 lost by abrasion, and frequently there is a dense white efflorescence 

 between the hairs, causing the areas to be very conspicuous. Length 

 6 to 7.5 millimeters. 



Host. — Unknown. 



This species is also rare in collections, and resembles somewhat 

 the examples of dbjectus which have the elytral pubescent spots 

 distinct. It can, however, be readily separated from that species by 

 having the pronotum regularly convex and without a median de- 

 pression and the median and posterior pubescent spots on the 

 elytra connected to each other and forming a distinct vitta.
