CASEY 



is more or less completely interrupted; middle tibiae of the male ob- 

 tusely dentate within; head without a callous band between the eyes. . .7 

 2 — Prothorax subparallel, only feebly inflated at the sides near apical third. 

 Body elongate, subparallel, moderately convex, dull in lustre, dark 

 brown or blackish and without evident metallic reflection above, similar 

 beneath though more shining, nearly glabrous above, the head densely 

 but not very coarsely punctato-rugose, with a strong callous transverse 

 band between the eyes and two longitudinal callous areas at base; eyes 

 moderate, not very prominent; prothorax three-fifths wider than long, 

 the sides parallel and very feebly sinuate from the anterior inflation to 

 the base, converging anteriorly; surface finely, densely punctate through- 

 out, except the rather approximate medial ridges, and thence to the 

 sides obliquely, though very moderately, impressed behind the middle 

 and with an elongate anterior and small basal callus in a line nearer the 

 medial ridges than the outer margin; central callus small and finely 

 prolonged posteriorly; elytra distinctly wider than the prothorax, 

 twice as long as wide, the sides parallel, gradually rounding and oblique 

 in posterior two-fifths, becoming only very faintly sinuate near the 

 obtusely acuminate apices, which are not evidently prolonged; surface 

 finely, deeply, very closely and uniformly punctato-cribrate throughout, 

 with series traceable to the sides of very coarse and well spaced per- 

 forate punctures, also having some elongate callous smooth lines on the 

 alternate intervals, especially toward the suture; under surface not 

 coarsely punctato-rugulose laterally, smooth and but feebly impressed 

 axially, the male with the middle tibiae unmodified, the apex of the fifth 

 ventral with a shallow transverse emargination, the female with the 

 apex narrowly and prominently rounded and entire. Length 1 1.0-13.7 

 mm.; width 4.0-4.8 mm. Massachusetts, Pennsylvania and District 

 of Columbia. [=^i3uprestis transversa Say] punctulata Schonh. 



A — Similar to the above but larger and stouter, the head larger, with 

 relatively smaller eyes, the transverse ridge finer and more acutely 

 elevated but not quite so strong, the prothorax nearly similar but 

 with the sublateral line of callus only narrowly interrupted or entire; 

 sides of the elytra similarly oblique posteriorly but with thesinuation 

 rather more obvious; prosternum of the male broadly, feebly con- 

 cave and closely, coarsely punctured, scarcely at all hairy, the abdo- 

 men strongly punctured throughout. Length (c?) 14.8 mm.; width 

 5.6 mm. North Carolina (Southern Pines) pinorum n. subsp. 



Prothorax constricted and sinuate at the sides basally, broadly inflated before 

 the middle 3 



3 — Elytral apices rather broad and obtuse, not evidently prolonged, the 

 form being nearly as in the preceding species. Body stout, oMong, 

 moderately convex, feebly shining, dark cupreous-brown above, some- 

 times with small green areas and occasionally with the elytra almost 

 entirely green, the under surface dark purplish-cupreous; head coarsely, 

 densely punctato-rugose, with a sharply elevated transverse biangulate 

 callous band between the eyes and two small approximate callous spots 

 at base ; eyes rather prominent ; prothorax three-fourths wider than long.
