NORTH AMERICAN BUPRESTID BEETLES 295 



Type, allotype, and paratypes. — Cat. No. 41012, U.S.N.M. Para- 

 types in the California Academy of Sciences. 



Described from a large series of specimens (one type). This sub- 

 species has been reared from sugarberry {Celt is laevigata Willde- 

 now), and from the material examined, seems to be confined to the 

 southwestern part of the country. The larval habits and male 

 genitalia are similar to those of the typical form, but since the males 

 can be readily separated by the tarsal claws on the anterior feet, it 

 seems advisable to consider it as a valid subspecies.

Male. — Form rather robust, subcylindrical, slightly flattened above, 

 and feebly shining; head bronzy green in front, becoming brownish 

 cupreous on the occiput ; pronotum and elytra brownish black, with a 

 more or less distinct aeneous or cupreous tinge, and the elytra orna- 

 mented with three more or less distinct pubescent spots; beneath 

 brownish black, with a cupreous or aeneous reflection, and more 

 shining than above. 



Head with the front rather wide, feebly convex, and slightly wider 

 at top than at bottom, the lateral margins feebly expanded from 

 bottom to top, and with a broad, shallow depression extending from 

 occiput to epistoma; surface sparsely, coarsely punctate, coarsely, 

 irregularly (more or less obliquely posteriorly) rugose, and sparsely 

 clothed with semierect, inconspicuous pubescence; epistoma narrow 

 between the antennae, and feebly, broadly, arcuately emarginate in 

 front ; antennae extending to about 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. 



Pronotum as long as wide, slightly narrower at base than apex, 

 and widest at apical third; sides feebly, arcuately rounded from 

 apical angles to middle, then more strongly narrowed to near base 

 where they are feebly sinuate, and the posterior angles rectangular; 

 when viewed from the side the marginal carina is moderately sinuate, 

 submarginal carina nearly straight, the two carinae rather widely 

 separated anteriorly, and connected to each other at base; anterior 

 margin strongly sinuate, and the median lobe strongly, broadly 

 rounded ; base feebly, broadly emarginate at middle of each elytron, 

 the median lobe feebly, broadly rounded, and subtruncate in front of 

 scutellum; disk strongly convex anteriorly, with an obsolete, linear 

 median depression, lateral depressions scarcely indicated, sides not
