REVISION OF TENEBRIONID SUBFAMILY COXIONTIN^^ lOI 



but strongly, sparsely, the abdomen minutely, punctate. Length 

 12.6 mm.; width 5.5 mm. Lake Co genitiva Csy. 



Body nearly similar but rather more convex, black, densely subopaque, 

 the elytra and under surface shining ; punctures without distinct 

 short hairs; head rather finely but strongly, not densely punctate, 

 the sinus rather deep, subparabolic, the lobes not impressed, the 

 anterior canthus more oblique and narrowly rounded ; prothorax 

 moi'e transverse and much more narrowed apically, somewhat 

 more than one-half wider than long, the sides broadly rounded, 

 becoming gradually more converging apically and parallel only 

 near the base ; apex rather deeply sinuate, only about three-fifths 

 as wide as the base, the angles broadly rounded ; surface rather 

 sparsely, very minutely punctate, becoming rather closely and more 

 strongly but still finely so laterally, the marginal bead fine; scu- 

 tellum large, triangular, very transverse; elytra relatively very 

 elongate, almost three times as long as the prothorax, somewhat 

 parabolically rounded behind, two-thirds longer than wide, the 

 surface nearly smooth, becoming somewhat rugulose apically, 

 finely, sparsely punctate, a little more strongly so laterally; under 

 surface nearly as in the preceding, the femora more minutely and 

 sparsely punctate, the pi'osternal lobe more narrowly and para- 

 bolically rounded at tip. Length 13.0 mm. ; width 5.8 mm. Not 

 labeled in Cab. Levette opacicollis n. sp. 



10 — Form rather stout, strongly convex, deep black, only moderately 

 shining, glabrous ; head rather coarsely but loosely punctate, very 

 minutely so at base, the sinus broad, subevenly rounded, the lobes 

 unimpressed, the anterior canthus broadly rounded; prothorax 

 unusually elongate, about two-fifths wider than long, the sides 

 broadly, rather feebly rounded though a little more converging 

 apically but barely becoming parallel even at base, the apex 

 evenly and moderately sinuate, almost thi'ee-fourths as wide as the 

 base, the angles right and but slightly rounded; surface very mi- 

 nutely, sparsely punctate medially, becoming rather coarsely and 

 deeply though not much more closely so toward the sides, the 

 marginal bead rather coarse; scutellum relatively rather small, 

 strongly transverse ; elytra but little more than twice as long as 

 the prothorax, parallel and straight at the sides, gradually and 

 arcuatelv narrowed and ogival in apical two-fifths, three-fifths 

 longer than wide ; surface nearly smooth, with a few obsolete 

 eroded lines, very finely, sparsely punctured throughout ; proster- 

 num finely, sparsely punctate, the process gradually slightly wider 

 posteriorly, with almost straight sides, its apex broadly rounded, 

 obsoletely reflexed, broadly concave on the disk ; hind femora 

 leather finely, remotely punctate. Length 14.0 mm. ; width 6.25 

 mm. A single example, labeled "Texas "but undoubtedly in 

 error and probably from the coast regions north of San Francisco.
