NORTH AMERICAN BUPRESTID BEETLES 279 



tinctly 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 the outer one, and not 

 turned inward. 



Fennale. — Differs from the male in having the front of head uni- 

 formly mahogany red, the surface strongly shining, not distinctly 

 granulose, feebly rugose, and with only a few white hairs behind 

 the epistoma; antennae slightly shorter; first two abdominal seg- 

 ments not sulcate at middle; prosternum and middle part of body 

 without long, erect hairs, and the tibiae unarmed at apex. 



Length, 3.25-4 mm.; width, 0.8-1 mm. 



Type locality. — Texas (no definite locality). 



Other locality. — Belvidere, Kans. 



Type, allotype, and paratypes. — Cat. No. 41011, U.S.N.M. Para- 

 types in collections of C. A. Frost and W. Knaus. 



Described from 25 examples (one type). Type, allotype, and 21 

 paratypes from Texas, without any definite locality, nearly al| of 

 which are from the Belfrage collection, and two paratypes collected 

 by W. Knaus, at Belvidere, Kans. 



This species is closely allied to abductus Horn and acaciae Fisher, 

 but can be separated from both these species by the pubescent spots 

 on the elytra being indistinct and the median one usually not de- 

 pressed, and also by the different shape of the male genitalia. Noth- 

 ing is known about the larval habits of this species.

Male. — Form small, moderately elongate, rather strongly flattened 

 above, and feebly shining; head subopaque, bronzy in front, becom- 

 ing brownish cupreous on the occiput; pronotum and elytra oliva- 

 ceous brown, with a more or less cupreous tinge, and each elytron 

 with three purplish brown or greenish black spots along the suture, 

 and ornamented with three pubescent spots; beneath cupreous, the 

 legs more or less greenish, and more shining than above. 



Head with front narrow, nearly flat, wider at bottom than at top, 

 the lateral margins strongly, broadly constricted at the middle, and 

 sometimes with a narrow, vague longitudinal groove ; surface densely, 

 finely granulose, sparsely, coarsely punctate, longitudinally rugose 

 on occiput, and sparsely clothed with long, recumbent, white hairs; 

 epistoma slightly transverse between the antennae, and broadly, very 

 deeply, arcuate.ly emarginate in front; antennae extending to middle 

 of pronotum, serrate from the fifth joint, and the outer joints about 

 as wide as long; eyes large, broadly oval, and slightly more acutely 

 rounded beneath than above.
