NORTH AMERICAN BUPRESTID BEETLES 159 



Elytra slightly wider than pronotum at base, and about equal in 

 width at base and behind middle ; sides parallel for a short distance 

 behind base, broadly, arcuately constricted in front of middle, 

 broadly, arcuately expanded behind the middle, then obliquely nar- 

 rowed to the tips, which are separately, rather narrowly rounded, 

 and strongly serrulate; sides of abdomen narrowly exposed above; 

 disk feebly flattened, with the costae vaguely indicated, sutural 

 margins slightly elevated behind the middle, and with broad, deep, 

 basal depressions; surface densely, finely imbricate-punctate, and 

 rather sparsely uniformly clothed with short, recumbent whitish 

 pubescence. 



Abdomen beneath finely, densely punctate, the punctures slightly 

 denser toward the sides, somewhat rugose at sides of basal segments, 

 and rather densely clothed with short, recumbent, whitish hairs ; first 

 and second segments each with a deep, smooth median groove, the 

 one on the second segment extending nearly to the posterior margin ; 

 last segment transversely truncate; vertical portions of the segments 

 rather densely but not conspicuously pubescent; pygidium coarsely 

 punctate, strongly carinate, the carina strongly projecting, and 

 rather acute at apex. Prosternum densely, finely, punctate, and 

 sparsely clothed with short, recumbent, whitish pubescence; pros- 

 ternal lobe broad, moderately declivous, and broadly but feebly, 

 arcuately emarginate in front; prosternal process broad, the sides 

 parallel to behind the coxal cavities, then obliquely narrowed to the 

 apex, which is acute. Tibiae slender, the anterior and middle pairs 

 armed with a short tooth on the inner margin at apex. Posterior 

 tarsi slightly shorter than tibiae, and the first joint as long as the 

 following two joints united. Tarsal claws dissimilar, anterior and 

 middle ones cleft near the apex, the teeth equal in length, and the 

 inner one not turned inward ; posterior claws cleft near the middle, 

 the inner tooth broad and very short. Genitalia not examined.

Horn (1891) in his original description gives the distribution as 

 the Lake Superior region, New York, and Massachusetts, but there 

 is only one specimen from the type locality in the Horn collection 

 under blanchardi. In the LeConte collection are two specimens 

 mounted on the same cardboard under this name, and labeled " Mass." 

 The under side of these two examples could not be examined, so the 

 writer was unable to decide if these specimens were "blanchardi or 

 anxius. If Horn erroneously placed specimens from Lake Superior
