144 CASEY 



aeneo-cupreous ; prothorax four- fifths wider than long, the sides obtusely 

 subprominent at the middle, thence strongly converging and evidently 

 arcuate anteriorly, and parallel and broadly sinuate basally; surface 

 rather more punctured but not or only feebly impressed along the mid- 

 dle, except the constant and distinct impressed spot near the apex, 

 the basal pit single or double, toward the sides strongly, obliquely im- 

 pressed behind the middle, the impression generally deep and con- 

 spicuous, the punctures coarse and dense, with the usual callous spots 

 very irregular; elytra nearly as in nigra in outline, the prolongation 

 not quite as long as wide in its parallel part as a rule, obtuse at the tips 

 but with the sutural angle sometimes acutely produced; surface rather 

 rough, coarsely, densely punctured laterally, finely and sparsely near 

 the suture, the striae rather coarse, not much impressed but visible 

 sometimes throughout the width, strongly punctured; callous spots 

 strong, elongate suturally, smaller and ramifying elsewhere; areolae not 

 very well defined and not much less coarsely punctured; under surface 

 as usual, the axial sulcus stronger in the male, and, on the prosternum, 

 broader, more concave and more pubescent; medial apical tooth 1(9) 

 short, broad and triangular but variable as usual. Length 17.0-20.5 

 mm.; width 5.6-6.8 mm. New York, Pennsylvania, Indiana, Illinois, 

 Kentucky and Wisconsin (Bayfield). [=Buprestis divaricata Say and

A — Similar in general form and size but very dark and obscure aeneous, 

 obscurely cuprascent beneath, more shining, the head more coarsely 

 rugose, the eyes a little larger and more prominent, the pronotum 

 more coarsely punctured laterally, with larger and very irregular 

 smooth spaces and the impressions obsolete, the median parts except 

 anteriorly very remotely punctate, not at all impressed behind the 

 middle, the basal pit similar; elytra with the punctures everywhere 

 well separated and almost to the side margins, where, however, they 

 become more or less transversely coalescent, the striae obvious and 

 impressed. Length (9) 19.0 mm.; width 6.1 mm. New York 

 (Buffalo) liinula n. subsp. 



B — Similar in general form but smaller and more slender, rather less 

 bright and darker aeneous, the under surface cupreous, with much 

 metallic green lustre medially; head with the depressed medial spot 

 bright green; eyes similar; prothorax similar but with the sides ob- 

 tusely angulate at the middle, the converging sides thence to the 

 apex straight; surface less impressed behind the middle, with the 

 sculpture toward the sides much coarser; elytra similar but more 

 elongate, the surface very much more coarsely and confluently punc- 

 tato-rugose, except near the suture, the impressed striae evident almost 

 throughout the width, the black smooth spots small but strongly 

 elevated, widely separated; two ridges of the fifth ventral strong as 

 usual in this group. Length (9) 16.5 mm.; width 5.2 mm. In- 

 diana incisa n. subsp. 



Body less stout and more convex, shining, dark aeneous with black spots as
