78 CASEY 



pronounced than in any other genus except Texania, and consists 

 of a deep, abrupt and angular emargination, not suggested at ail in 

 the female. The male also has the median parts of the sterna more 

 impressed and hairy than in the female as a rule, a character suggest- 

 ing Buprestis and other following genera. The species are rather 

 numerous and may be separated by the following characters: — 



Subsutural groove of the elytra abbreviated, attaining basal third or fourth; 

 body more sombre in coloration, though similarly shining; basal sul- 

 cus of the abdomen glabrous in both sexes 2 



Subsutural groove continuing to the base of the elytra though shallow and 

 sometimes subinterrupted near the base; lustre of the body more 

 brightly aeneous or cupreous as a rule; basal sulcus of the abdomen, 

 as well as the sterna, more pubescent in the male 8 



2 — Sutural angles of the elytra distinctly dentate or spinulose; males not 

 rare 3 



Sutural angles not prolonged though sometimes feebly subprominent; 

 males apparently much less abundant than the females 4 



3 — Depressions of the elytra finely, densely and evenly punctulate, shining, 

 blackish-aeneous, the depressions less shining and more cupreous; under 

 surface obscure aeneous and partially cinereo-pubescent; head well 

 developed, unevenly, moderately punctate, with a very large deep 

 frontal impression which is narrowed posteriorly along the median 

 line; eyes rather prominent; antennae not extending to the base of the 

 prothorax even in the male; prothorax rather transverse, fully two- 

 thirds wider than long, the sides broadly rounded anteriorly, sometimes 

 prominent and occasionally distinctly angulate ( 9 ) , parallel toward 

 base and generally nearly straight; surface broadly, roughly and un- 

 evenly sculptured and biimpressed laterally, the two punctate sulci 

 very feeble, the elevations smooth; scutellum small; elytra scarcely 

 more than three-fourths longer than wide, the sides parallel, obliquely 

 and arcuately converging in apical two-fifths and more or less visibly 

 serrulate, the subsutural groove rather feebly concave, the second con- 

 stricted and subinterrupted at and behind the middle, the sublateral 

 carina nearly entire, the next distinct before the middle, uniting with 

 the submarginal behind the humeri; under surface smooth, with small 

 patches of fine close j)unctures. Length (ci') 20.0-22.5, (9) 25.0-28.5 

 mm.; width (0^)6.9-7.5, (9) 8.6-9.7 mm. Atlantic region, — Massa- 

 chusetts to Florida. [=nov(B-boracensis Fitch, Buprestis virginiensis 

 Drury, virginica Say and Harris, virginiaca Gmel., and cu preomaculata 

 Goezej virginiensis Drury 



A — Nearly similar to virginiensis but more elongate and with the second 

 elytral sulcus more interrupted at the middle, blacker in color, very 

 shining, the under surface duller cupreo-icneous; head nearly similar 

 but more coarsely, sparsely punctate, the eyes less convex; prothorax 

 much less transverse, but little more than one-half wider than long,
