NORTH AMERICAN BUPRESTID BEETLES 135 



and the second segment not grooved at the middle ; tooth at apex of 

 anterior and middle tibiae less distinct, and the claws alike on all 

 the feet, similar to those on the posterior feet of the male. 



Length, 7.5-10.5 mm. ; width, 2-2.75 mm. 



Redescribed from specimens reared from oak (Quercus sp.) col- 

 lected at French Creek, W. Va., by F. E. Brooks. These specimens 

 agree very well with the description given by Ziegler, and seem to 

 be distinct enough to retain as a valid species. 



Type locality. — Georgia. Described from the Haldeman collec- 

 tion, but present location of type is unknown to the writer. 



DISTRIBUTION 



Material examined:

ford, June 24, (D. J. Caffrey).

Variations. — The color and depressions on the pronotum are more 

 or less variable in this species, and the tips of the elytra are usually 

 broadly rounded, but a few examples were examined in which the 

 tips were subacute. 



Host. — This species has been reared from oak (Quercus sp.) 

 This species is very closely allied to acutipennls Mannerheim, and 

 there will be some difficulty in separating some specimens from that 

 species. In acutipennis the elytra are usually blue, with an occa- 

 sional black specimen, and in all of the examples examined, the ver- 

 tical portions of the second abdominal segment are entirely glabrous, 

 whereas in quadriimpressiis the elytra are more olivaceous black, and 

 the vertical portions of the second abdominal segment are pubescent, 

 although in some examples the portions are very sparsely clothed.
