STUDIES IN THE AMERICAN BUPRESTID^ I3I 



Eyes not at all prominent, the intermediate male tibiae more or less distinctly 

 swollen or angulate internally; prothorax sinuate at apex throughout. . .9 



2 — Prothorax evenly narrowed from base to apex, the latter sinuate as 

 usual 2 



Prothorax parallel, the sides rounding and converging anteriorly to the 

 apex 4 



3 — Surface feebly convex, very roughly sculptured; body broad, oblong- 

 oval, rather shining, dull cupreous, with the elevations black; under 

 surface blackish and obscure cupreous; head roughly sculptured, with 

 uneven callosities, which tend to form a transverse band between the 

 eyes, the latter only moderately prominent (9), or strongly so (d^); 

 prothorax one-half to three-fourths wider than long, the sides feebly 

 arcuate, sometimes feebly subprominent before the middle; surface 

 finely, sparsely punctate, with a more strongly impressed medial sub- 

 apical area, coarsely and confluently punctate laterally, with sublateral 

 line of broken callous spots and an impression near lateral fifth behind 

 the middle; ante-scutellar cavity distinct, single; scutellum small; 

 elytra scarcely wider than the base of the prothorax, three-fourths or 

 more longer than wide, the oblique sides posteriorly becoming evidently 

 sinuate before the tips, which are more broadly sinuate than in any other 

 species of the group, strongly bispiculose; surface densely punctate, 

 sparsely and finely near the suture, generally vdth evident rows of 

 coarser punctures, the alternate intervals with elongated and con- 

 spicuous irregular raised polished black areas; under surface coarsely, 

 rugosely punctate, the pectoral channel much broader, more evenly 

 concave and densely sculptured and hairy in the male than in the female 

 as usual. Length 13.5-18.3 mm.; width 4.7-6.6 mm. Virginia (Nor- 

 folk) and North Carolina (Southern Pines) to Florida. [ = Buprestis 

 obscura Fabr., baliimorensis Hbst., and consimilis and pruinosa Gory]. 



ob.«cura Fabr. 



Surface evidently more convex and smoother, form more elongate, still 

 darker in coloration, with more aeneous than cupreous lustre; head 

 coarsely, very densely but more evenly punctato-rugose, without very 

 marked callous spots, the pubescence longer and much more conspicu- 

 ous; eyes more widely separated; prothorax nearly similar in form but 

 rather less transverse, the sides evenly and feebly arcuate throughout; 

 surface much more even and more evenly punctate, rather closely so, 

 with similar anterior punctured area and basal pit medially, the punc- 

 tures relatively less coarse and more evenly dense and confluent later- 

 ally, not impressed sublaterally behind the middle; scutellum larger; 

 elytra similar though rather more elongate, the sculpture of the 

 same general nature but less coarse and more even, the callous spots 

 smaller, less elevated and much less conspicuous; sides posteriorly 

 becoming straight and not sinuate toward the tips, which are much 

 more narrowly and normally sinuate and bidenticulate; under surface 

 nearly similar. Length (?) 18.8 mm.; width 6.3 mm. Texas.
