STUDIES IN THE AMERICAN BUPRESTIDiE 8l 



7 — Body broad and only moderately convex, shining, black, the depressions 

 obscurely cupreous, beneath dull cupreous; polished black areas with 

 feeble cupreous reflection; head as in virginicnsis, except that the an- 

 tenna" are shorter and thicker than in the female of that species, the 

 outer joints much less elongate; prothorax more transverse, very prom- 

 inent laterally, and much wider than at base at about apical third, the 

 sides thence converging and bisinuate to the base; surface sculptured 

 in general as in that species, the depressions much more coarsely rugose 

 and the median smooth line broader, the basal callus at lateral fourth 

 much larger and more conspicuous; elytra broader, the converging 

 sides posteriorly more rounded, with scarcely a trace of serrulation, the 

 sculpture having the same general arrangement but with the elevations 

 feebler and less sharply defined ; under surface with the usual sculpture. 

 Length ( 9) 28.0 mm.; width lo.omm. Florida prominensn. sp. 



8 — Smooth polished areas of the elytra but feebly elevated and less abruptly 

 formed, in some parts dilated, the general sculpture nearly as in vir- 

 giniensis 9 



Smooth areas very abruptly formed, higher and linear in form throughout; 

 sutural angle of the elytra never prolonged or dentiform; antennae 

 thicker; elytra very evidently wider than the prothorax; species more 

 boreal in habitat 10 



9 — Form narrower and more elongate than in virginiensis, moderately con- 

 vex, polished, generally with strong golden-aeneous lustre throughout 

 above and beneath but occasionally black and without much metallic 

 lustre; head well developed, unevenly punctured and rugose, the deep 

 frontal sulcus not dilated anteriorly; eyes moderate, slightly prominent, 

 the antenna slender; prothorax but little more than one-half wider 

 than long, the sides parallel and nearly straight, gradually broadly 

 rounding and very moderately converging anteriorly; surface sculp- 

 ture as usual, except that the median smooth line is very broad and 

 feebly convex; elytra about twice as long as wide, but little wider than 

 the prothorax, the sides very gradually converging and feebly arcuate 

 posteriorly, the apex unusually narrow, with the sutural angles strongly 

 prolonged and spiculiform; surface with the smooth convex parts to- 

 gether much exceeding in area the depressions, the latter finely and for 

 the most part densely punctate; sutural sulcus becoming subobliterated 

 basally; under surface with the pubescence of the finely and densely 

 punctate areas very distinct, ashy white. Length (c?) 22.7-24.0, ( 9) 

 24.0-28.0 mm.; width (d^) 7.5-8.2, ( 9) 7-7-9-2 mm. Southern Atlan- 

 tic States. [ = Buprestis georgiana Lee. , and liberta Lap.-Gory nee Germ.]. 



georgiana Lee. 



Form and sculpture nearly as in georgiana but narrower, the aeneous lustre 

 varied with clouds of metallic bluish-green toward the sides of the elytra, 

 the under surface bright subcupreous; head nearly similar, the eyes much 

 less convex; prothorax trapezoidal, barely one-half wider than long, the 

 sides distinctly converging and nearly straight from base to apex, very 

 feebly arcuate anteriorly, the sculpture nearly similar; elytra inform and 

 sculpture nearly as in georgiana but more evidently wider than the pro-
