NORTH AMERICAN BUPRESTID BEETLES 267 



Described from a male and female collected at the type locality, 

 April 28, by H. S. Barber. 



This species resembles addendus Crotch and abjectus Horn, but 

 can be separated from the former by having a distinct median de- 

 pression on the pronotum, the basal and median pubescent spots on 

 the elytra not connected, and the head glabrous in both sexes, and 

 from abjectus it differs in having the pronotum only moderately 

 convex, with a distinct, elongate median depression, and the color 

 above is reddish cupreous.

Male. — Form moderately robust, subcylindrical, feebly flattened 

 above, subopaque; head aeneo-cupreous ; pronotum and elytra uni 

 formly reddish or brownish cupreous, with a more or less distincf; 

 aeneous tinge on some parts, and each elytron ornamented with three 

 pubescent spots; beneath similar in color but more shining than 

 above. 



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

 top than at bottom, the lateral margins vaguely, arcuately expanded 

 near middle, and with a rather deep, broad, concave depression ex- 

 tending from occiput to epistoma ; surface densely, finely granulose, 

 sparsely punctate, coarsely, irregularly rugose, and rather densely 

 clothed with long, recumbent, whitish pubescence; epistoma not 

 transverse between the antennae, and broadly, deeply, arcuately 

 emarginate in front; antennae extending nearly to middle of pro- 

 notum, serrate from the fifth joint, and the outer joints as wide as 

 long; ej T es large, broadly oval, and equally rounded above and 

 beneath. 



Pronotum about one-fifth wider than long, feebly narrower at 

 base than apex, and widest near middle ; sides vaguely rounded from 

 apical angles to behind middle, then more strongly narrowed to 

 near the base, where they are slightly sinuate, and the posterior angles 

 rectangular; when viewed from the side the marginal carina is 

 strongly sinuate, the submarginal carina nearly straight, more or 

 less obliterated behind middle, and the two carinae broadly separated
