sides and in a well defined humeral spot; abdomen only very slightly 

 obscure peripherally; hairs short, stiff, yellowish; head rather small, 

 with somewhat more prominent eyes than in the preceding two forms 

 and differing very radically in being coarsely, deeply and rather 

 closely punctate, except antero-medially, the antero-lateral rugosity 

 extremely fine and feeble; antenna? longer and much more slender 

 than in blanda but nearly as in planipennis; prothorax two-fifths 

 wider than long, the sides rather unevenly rounded, converging 

 posteriorly, becoming feebly sinuate toward the basal angles, which 

 are very sharp and prominent; base subevenly and feebly arcuate, 

 much narrower than the apex, which is sinuate, the angles broadly 

 rounded; surface coarsely, very deeply, irregularly but on the whole 

 not very closely punctate throughout, only moderately concave and 

 reflexed at the sides and much more narrowly than in either of the 

 preceding, the basal impressions broad, feeble and diffuse as usual 

 in the cribricollis type; elytra only about a fourth longer than wide, 

 almost parallel, being but very slightly broader behind the middle 

 than at base, two-fifths, or slightly more, wider than the prothorax, 

 the striae very distinct, strongly, rather closely punctured and feebly 

 impressed; intervals feebly convex, finely but strongly, rather 

 sparsely and irregularly punctate, the punctures a little smaller 

 than those of the striae, the two punctures of the third interval 

 indistinct. Length (cf ) 8.0-8.3 mm.; width 2.8-2.9 mm. Kansas. 

 [cribricollis Lee. nee Dej., and planipennis Horn nee Lee.]. Three 

 examples brevipennis Zimm. 



Body still smaller and rather narrower, strongly shining and testaceous 

 throughout, the elytra piceous-black, without metallic glint, very 

 gradually testaceous basally and evenly so throughout the width 

 in about basal third and also along the sides; hairs only moderately 

 short, stiff and yellowish; head nearly as in the preceding but larger 

 and except that the punctures, though rather coarse, are very much 

 smaller and sparser; antennae rather long and slender; prothorax 

 relatively smaller and less transverse, otherwise almost similar, 

 except that the punctures are less coarse and much sparser and the 

 sides more broadly concave and reflexed, relatively almost as widely 

 so as in planipennis; elytra about a fourth longer than wide, much 

 more inflated posteriorly and much wider posteriorly than at base, 

 almost four-fifths wider than the prothorax; striae rather finer and 

 shallower, the punctures relatively stronger, somewhat wider than 

 the striae and rather widely but irregularly separated, the intervals 

 flat, finely, sparsely and irregularly punctate, the punctures very 

 much smaller than those of the striae, much finer than in brevi- 

 pennis and, on some of the interval, tending to unilinear arrange- 

 ment; apices obliquely and feebly arcuate, becoming just visibly 

 and broadly sinuate externally but more evidently so than in plani- 

 pennis, where they are arcuate, becoming simply straighter externally. 

 Length (9) 7.8 mm.; width 2.7 mm. Wyoming (Green River).
