coarsely punctate, finely granulosa broadly rounded at apex. Prosternum glab- 

 rous, coarsely, deeply, rather densely punctate, deeply, broadly, transversely 

 concave anteriorly ; anterior margin truncate, without a median lobe. An- 

 terior femur with a short, acute tooth, which is not dentate on outer margin. 

 Anterior tibia distinctly arcuate, unarmed; middle tibia slightly arcuate; pos- 

 terior tibia straight. 



Length 12 mm., width 5 mm. 



Eedescribed from the female holotype in the collection of Mont. A. 

 Cazier. 



Male. — Differing from the female in having the antenna strongly bipectinate 

 from the fourth segment, with the internal ramus of each segment slightly 

 longer than the external one, and the last segment bifurcate, the last visible 

 sternite very broadly, shallowly emarginate at apex, the eighth tergite more 

 sparsely punctate, and the anterior and middle tibiae more strongly arcuate. 



Type locality. — Twenty miles east of Tuba City, Ariz. 



DISTEIBTJTION 



From material examined: 



Arizona : No definite locality, one male. Near Tuba City, July 22, 1937, female 

 holotype, male allotype, and male and female paratypes (R. P. Allen). 

 Woodruff, June 26, one female. 



Colorado: Five miles north of Delta, June 30, 1938, one male (R. Bauer). 



Hos t. — Unknown. 



Very little variation was observed in the few specimens examined. 

 In the male allotype the pronotum is widest at the middle, with the 

 sides uniformly rounded, and in one of the paratypes there are two 

 vague purplish-black spots on each elytron, but these can be seen 

 only in certain lights, and the clypeus is a little more deeply emar- 

 ginate in some specimens. The color varies from bluish green to 

 golden green. The length is from 11 to 13.5 mm. 



This species resembles platti Cazier, but it differs from that species 

 in having the clypeus shallowly emarginate in front, the dorsal sur- 

 face of the body shining, the anterior femur armed with an acute 

 tooth, which is not dentate on the outer margin, and the antenna of 

 the male bipectinate.

 (Fig. 107 ; fig. 126, F) 



Chrysobothris bicolor Horn, 1894, Calif. Acad. Sci. Proc. (ser. 2) 4: 328, 386- 

 367; Chamberlin, 1926, Cat. Buprestidae North Amer., p. 139; Obenbevger, 

 1934, in Junk (pub.), Coleopt. Cat, pt. 132, p. 612. 



Female — Broadly elongate, moderately convex above, slightly shining; pro- 

 notum uniformly purplish brown ; elytra uniformly violaceous, with more or 

 less distinct greenish and bluish reflections in different lights; beneath pur- 

 plish brown at sides, greenish blue to bronzy brown on median parts, and 

 slightly more strongly shining than above. 



Head uniformly purplish brown, slightly cupreous, with a vague, smooth 

 chevron on vertex, and a vague, narrow, longitudinal carina on occiput ; front 

 nearly flat; surface coarsely, densely punctate, slightly rugose behind clypeus, 

 sparsely, uniformly clothed with short, semierect, white hairs, intervals indis- 

 tinctly granulose; clypeus broadly, rather deeply, subangularly emarginate in 

 front, arcuately rounded on each side. Antenna uniformly purplish, gradually 

 narrowed to apex ; intermediate segments compact, distinctly wider than long, 

 broadly rounded at outer margins: third segment as long as following three 

 segments united.
