NORTH AMERICAN BUPRESTID BEETLES 317 



exterior angle rectangular and not prolonged. Tibiae slender, 

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

 distinct tooth on inner margin at apex. Posterior tarsi nearly as 

 long as the tibiae, and the first joint as long as the following three 

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

 the inner tooth broad, much shorter than outer one, and not turned 

 inward. Genitalia similar to those of celti. 



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

 broader, and the lateral margins parallel to each other; antennae 

 shorter; prosternum less densely punctured and not clothed with 

 long, erect hairs, and the tibiae without a distinct tooth at apex. 

 Length, 4.5-5 mm. ; width, 1-1.25 mm. 

 Type locality. — " Tanke Verde," Ariz. 



Other localities. — Texas: Beeville, Kerrville, Dallas, Devil's River, 

 and Sheffield. 



Type, allotype, and paratypes. — Cat. No. 41015, U.S.N.M. Para- 

 types, California Academy of Sciences. 



Described from 15 specimens (1 type). The type, allotype, and 

 two paratypes reared from catclaw {Acacw greggii Gray) collected 

 at the type locality by M. Chrisman (Hopk. U. S. No. 13700b 4 ) ; three 

 paratypes labeled " Texas " from the Belf rage collection ; three 

 paratypes collected at Kerrville, Tex., April 22, 1908, and one at 

 Devil's River, Tex., May 3, 1907, by F. C. Pratt ; one paratype col- 

 lected at Beeville, Tex., April 22 (Hubbard and Schwarz) ; one para- 

 type from Dallas, Tex., April 25, 1907 (Schwarz and Pratt) ; and 

 two paratypes collected at Sheffield, Tex., April 24, 1924, by J. O. 

 Martin. 



There are some slight variations among the paratypes, the head 

 varying in color from bronzy green to reddish cupreous, and the 

 median depression on front of head and pronotum are more or less 

 variable in distinctness. 



This species resembles olentangyi Champlain and Knull, but can 

 be readily separated from that species by having the prosternal lobe 

 broadly rounded or subtruncate in front, and by the different shape 

 of the male genitalia.
