nearly one-half longer than wide, barely as wide as the prothorax, 

 more rapidly rounding in apical two-fifths, broadly ogival at tip; 

 striae fine but well impressed, minutely subcomminuted, the scu- 

 tellar short, oblique, deeply impressed; intervals broadly but evi- 

 dently convex. Length (9) 6.5 mm.; width 2.78 mm. Michigan 

 (Marquette), Sherman marquettensis n. sp. 



Form oblong-oval, slightly more abbreviated than in the preceding, deep 

 black, the upper surface bright polished bronzy-aeneous; head not 

 quite so large, barely half as wide as the prothorax, the eyes feebly 

 convex, the very small linear strides and the antennae throughout 

 nearly similar; prothorax rather more than one-half wider than long, 

 the sides more evenly arcuate, rounding in basally, the basal angles 

 more obtuse as well as rounded, the puncture not so coarse or deep, 

 the remainder nearly as in the preceding, except that the base is not 

 so evidently sinuate laterally; elytra shorter but otherwise nearly 

 similar in outline, barely as wide as the prothorax; striae finer, feebly 

 comminuted in part, the scutellar moderate, not so oblique, very fine, 

 not impressed and much disintegrated; intervals flat; middle tibiae 

 of the male serrate within, slightly bent. Length (cf) 6.2 mm.; 

 width 2.65 mm. Michigan (Marquette), Sherman. 



aeneopolita n. sp. 



19 Body oblong-suboval, rather broad, convex, black, the upper sur- 

 face more or less distinctly bronzed; legs piceous-black, the femora 

 blacker; head half as wide as the prothorax, the eyes rather feebly 

 convex, the strioles moderate, oblique; antennae rather short, not 

 extending to the thoracic base, black, the two basal joints rufous, 

 clouded above with blackish; prothorax one-half wider than long, the 

 sides broadly arcuate, more so and converging anteriorly, subparallel 

 basally, the basal angles right, slightly blunt because of a feeble 

 arcuation of the base outside of the broad feeble sinuses, the puncture 

 moderate, twice as far from side as from base; apex two-thirds as 

 wide as the base, deeply sinuate, the angles blunt at tip; impressions 

 very feeble; inner fovea obsolete,' excepting the short incised line, 

 the outer oblique but very feeble; elytra not quite one-half longer 

 than wide, about as wide as the prothorax, gradually rounding be- 

 hind; striae fine, minutely subpunctulate or comminuted, the scu- 

 tellar long, oblique; intervals flat or nearly so. Length (d 71 9) 6.0 

 -7.0 mm.; width 2.8-3.1 mm. Nebraska. Four examples. 



nebraskana n. sp. 



Body nearly as in nebraskana but more elongate and smoother, bright 

 bronze above; legs black, with rufescent tibiae; head relatively a 

 little smaller, not quite half as wide as the prothorax, the eyes slightly 

 more convex; antennae similar in coloration but somewhat longer and 

 more slender, extending to the thoracic base; prothorax broader, 

 three-fifths wider than long, otherwise very nearly as in the preced- 

 ing; elytra longer, fully one-half longer than wide, similar in general 

 form and relationship, the lateral series more broadly interrupted, 

 although in this part of the section the interruption is not very con- 

 stant in extent; in the type of the present species there is a broad 

 sharp interruption on the left elytron, while a single puncture lies
