NORTH AMERICAN BUPRESTID BEETLES 249 



Described from 69 specimens (1 type), all collected at the locali- 

 ties mentioned above. This large series of paratypes show consider- 

 able variations, the color varying from bronzy green to cupreous 

 brown, and the pubescence from white to yellowish white. The 

 depressions on front of head and middle of pronotum vary consid- 

 erably in distinctness. In some of the examples examined the pro-' 

 notum is widest along the anterior half and the sides are nearly 

 parallel from the apical angles to near the base, whereas in others 

 it is widest at apical third, and the sides are strongly, arcuately 

 rounded. Length 4.5 to 7 millimeters. F. C. Carr collected a large 

 series of this species on Malvastrwm coccinev/ni (Pursh) Gray, which 

 may be the host plant for the larvae.

Figure 63 



Male. — Form rather slender, subcylindrical, and moderately shin- 

 ing; above olivaceous green, with a rather distinct cupreous tinge, 

 and each elytron ornamented with a pubescent vitta ; beneath bronzy 

 green, with a slight cupreous reflection and more shining than above. 



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

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

 top to bottom, and with a rather broad, shallow groove extending 

 from the occiput to near the epistoma; surface densely granulose, 

 more or less coarsely rugose, and rather densely clothed with long, 

 recumbent, silvery white hairs; epistoma not transverse between the 

 antennae, and vaguely, broadly, arcuately emarginate in front; 

 antennae extending to middle of pronotum, serrate from the fifth 

 joint, and the outer joints nearly as wide as long; eyes large, broadly 

 oval, and about equally rounded above and beneath. 



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

 apex, and widest along apical half; sides nearly parallel to behind 

 middle, then obliquely narrowed to the posterior angles, which are 

 rectangular ; when viewed from the side the marginal and submargi- 

 nal carinae are strongly sinuate, widely separated anteriorly, and 

 connected to each other behind the middle ; anterior margin strongly 

 sinuate, with the median lobe broadly rounded, and rather strongly 

 produced; base slightly emarginate at middle of each elytron, and 

 the median lobe broadly rounded, and subtruncate in front of scu- 

 tellum; disk strongly convex, without median depressions, but with 

 a broad, oblique depression on each side along the lateral margin, 

 and with vaguely indicated prehumeral carinae ; surface coarsely, 

 deeply rugose, or scabrous, finely, sparsely punctate between the 

 rugae, and sparsely clothed at the sides with long, recumbent white
