136 CASEY 



lose apices than in the preceding; surface less rugosely though coarsely 

 and rather confluently punctate laterally, the punctured striae fine but 

 evident suturally, the dark spots elongate and numerous but only 

 feebly elevated, the punctured areolae very irregular but distinct, some- 

 times with more greenish-metallic lustre; under surface (9) deeply 

 sulcate along the prosternum, the metasternum flat, the medial tooth 

 of the apical sinus long, slender and aciculate. Length ( $ ) 16.0 mm. ; 

 width 5.5 mm. Illinois (southern) gaudens n. sp. 



12 — Body elongate and rather narrow, convex, gradually inflated posteriorly, 

 slightly shining, dark cupreous, obscure above, brighter when living; 

 head rather small, densely, moderately coarsely punctured, generally 

 with a V-shaped central callus; prothorax two-thirds wider than long, 

 the sides broadly rounded and moderately converging before, becom- 

 ing parallel and broadly sinuate behind, the middle; surface broadly, 

 indefinitely impressed sublaterally behind the middle, densely but only 

 moderately coarsely punctate and with irregular callous spots laterally, 

 sparsely and finely punctate medially, the subapical spot scarcely 

 impressed, the basal pit variable, generally small but sometimes double; 

 elytra at base but little wider than the prothorax, gradually broader 

 posteriorly, and, behind the middle, evidently wider than at base, the 

 sides thence very gradually rounding and converging, becoming sinuate 

 before the sharply bidenticulate apices; surface unusually rough, the 

 cupreous areolae more deeply impressed, the raised spots numerous 

 and prominent; under surface deeply impressed along the axial line 

 nearly to the apex of the first ventral. Length 15.0-17.0 mm.; width 

 4.9-5.8 mm. New York to Florida. [ =indistincta Mels.] . . lurida Fabr. 



Body nearly as in lurida in general coloration and moderate lustre but more 

 parallel and relatively stouter, less dilated posteriorly; head less densely 

 punctate, the callous spots similarly very irregular in a transverse inter- 

 ocular region; prothorax larger and much less transverse, barely one- 

 half wider than long, similar otherwise, except that the anterior densely 

 punctate medial spot is more impressed and the areas of dense punctua- 

 tion at each side of the sublateral fine of callus anteriorly are more 

 impressed, causing the vittae to be more prominent; elytra more rapidly 

 attenuate posteriorly, scarcely more than twice as long as wide, but 

 slightly inflated behind the middle, the surface very much smoother 

 than in lurida and with the punctured series very distinct and entire 

 nearly to lateral third; sides only sHghtly sinuate before the apices; 

 under surface ( 9 ) nearly similar, except that the sinus of the fifth 

 ventral is shallower, with the median tooth shorter, triangular. Length 

 (9) 17.0 mm ; width 5.9 mm. Texas seriata n. sp. 



Body shorter than in either of the preceding, shining, aeneous, the head and 

 sides of the pronotum cuprascent, the entire under surface more bril- 

 liant cupreous; head coarsely, densely punctate, with a broadly V- 

 shaped central callus, including a depressed area; there is also a trans- 

 verse band of irregular callous spots between the antennae; prothorax 

 nearly as in lurida but with the oblique impressions behind the middle 

 still stronger; elytra scarcely twice as long as wide, moderately inflated
