2io MEMOIRS ON THE COLEOPTERA 



punctulation; elytra not evidently inflated subbasally and scarcely 

 wider than the prothorax, fully a fourth wider than long, the arcuate 

 sides rather converging posteriorly; three entire striae not very 

 coarse, the fourth and fifth represented by the faintest traces at 

 apex only, the sutural very short, extending from near the middle to 

 well before the apex, the subhumeral present in a very short line near 

 basal third, the oblique humeral long and very fine but distinct; 

 pygidia sparsely and moderately punctured, very nearly as in so- 

 laris; sterna as in the preceding, the prosternal lobe rather broadly 

 rounded; external side of the hind tibiae with two series of short, very 

 thick and remotely separated spinules. Length 6.2 mm.; width 

 4.2 mm. Kansas coruscans n. sp. 



9 Pygidia coarsely, more closely and very conspicuously punctured. 

 Body rather elongate, oblong-oval, convex, polished, black, the 

 abdomen and legs rufo-picescent; elytra nubilously blackish along 

 the sides, the red areas nubilously merging into black at apex, the 

 medio-basal black plaga extending behind the middle, wider than 

 long and slightly inflated posteriorly; head finely, not very sparsely 

 punctulate, the mandibles closely and conspicuously, the ambient 

 line entire; prothorax of the usual form, the sides evenly and evi- 

 dently arcuate, rounding apically ; outer lateral stria coarse and entire, 

 the inner less coarse, not quite entire, its posterior end tending to 

 form a short hook inward; elytra scarcely one-half longer than the 

 prothorax and barely wider, not at all inflated subbasally, the three 

 entire striae coarse and well impressed, the fourth and fifth wholly 

 obsolete, the sutural rather deep, extending from basal two-fifths to 

 near the apex, the humeral represented by a series of small and 

 elongate, widely separated punctures in apical half, all trace of 

 humeral and subhumeral wanting in fully basal half, the oblique 

 humeral long and fine but distinct; prosternal lobe parabolically 

 rounded, the mesosternal sinus deep; hind tibiae with the external 

 spines stout and widely spaced. Length 5.2-7.0 mm.; width 3.8- 

 4.35mm. New Mexico (Fort Wingate and Cimarron). The Cimar- 

 ron examples are exactly like the type, but have the punctures of the 

 pygidia not quite so coarse and more widely separated.

Pygidia less coarsely and more sparsely, the propygidum as a rule re- 

 motely, punctate 10 



10 Form subquadrate-oval, convex, shining and black, the legs black 

 throughout; red areas of the elytra not quite attaining the sides or 

 apex, the black basal plaga extending behind the middle and not 

 much inflated posteriorly, about as long as wide; head with entire 

 ambient line, the surface minutely, sparsely punctulate, the mandibles 

 equally minutely but closely so; prothorax of the usual outline, the 

 converging sides arcuate, more so apically, the lateral striae only 

 moderately coarse, abruptly formed, the inner generally not quite 

 attaining the base, the intervening flat surface wholly devoid of 

 anterior rugulosity; elytra a fourth wider than long and, near the 

 middle, slightly wider than the prothorax, not inflated subbasally, 

 the three entire striae rather coarse, the fourth and fifth feebly
