each of its side walls; surface opaculate, the punctures strong and 

 rather close-set but much less coarse than in castanece or pocularis, 

 very sparse basally and wanting in a small area just behind the 

 apical cavities; median line barely impressed; scutellum with rather 

 small feeble areolse, wanting near the sides; elytra not quite one-half 

 longer than wide, very feebly cuneiform, about a fourth wider than 

 the prothorax, the surface with two very faint longitudinal impressed 

 lines, nearly flat on the disk and subopaque, shining and with 

 deeper punctures laterally, the shallow areolae elongate-oval, open 

 behind; pygidium convex, opaque, with moderate shallow punctures, 

 gradually smaller basally, each bearing a distinct coarse hair, the 

 surface at apex smooth and polished; hind tarsi moderately slender 

 and compressed, barely three-fourths as long as the tibiae, the basal 

 external impression of each joint smaller and more sharply denned 

 than in brevisetosiis. Length 10.9 mm.; width 5.5 mm. Iowa 

 (Keokuk). Texas LeConte. A single specimen. [Crem. ivalshi 

 Westw.] retractus Lee. 



Legs rufous or rufo-piceous; elytral foveolae very much smaller than in 

 any of the preceding species; body more slender, never very deep 

 black, shining above, polished beneath; body blackish-piceous, the 

 apical parts of the head and the apical and basal thoracic angles 

 rufescent; erect hairs sparse, very short, attenuated from their bases; 

 head with rather fine, irregularly sparse punctures, the clypeus 

 strongly reflexed, sinuato-truncate, the apical inferior inflexed surface 

 smooth; mental notch as in castanece; prothorax slightly less than 

 one-half wider than long, the sides from the long oblique straight 

 line limiting the hind angles nearly straight and feebly or scarcely 

 at all converging to the rounded apex of the anterior processes, the 

 internal cavities adjoining which are deep and large; hind angles 

 piceo-rufous, acute, with arcuate external outline, much retracted 

 and depressed below the general level; punctures only moderately 

 large, not very deep or dense and somewhat unevenly distributed, 

 sparse basally and coarser, though rather less well defined, laterally; 

 scutellum with moderate areolae, wanting toward the sides; elytra 

 stibparallel but with rather prominent humeri and broadly rounded 

 external angles at apex, nearly one-half longer than wide and dis- 

 tinctly wider than the prothorax, the longitudinal impressed lines 

 almost obsolete; surface feebly and vaguely subrugulose, the areolae 

 well separated, small and very narrow, the flanks with very moderate 

 or rather small, deep and rounded punctures; pygidium convex, 

 rather closely, moderately punctate, the apical part more sparsely 

 punctate but not impressed; hind tarsi strongly compressed, slender 

 on the edges, distinctly shorter than the tibiae. Length 8.3-10.7 mm. ; 

 width 4.0-5.1 mm. Colorado (Denver and Fort Collins) and Kansas. 



incisus n. sp. 



7 Body small in size, rather elongate, not very depressed above, shining, 

 black, the punctures of the upper surface bearing each a small erect 

 whitish scale, which is deeply plumose at apex; head evenly convex, 

 closely punctate, more gradually declivous anteriorly than usual, 

 the clypeus abruptly and very strongly reflexed, sinuato-truncate;
