usual ; head coarsely, subevenly and rather closely punctured ; 

 prothorax less transverse than in bifossiceps^ two-fifths wider 

 than long, subsimilar in form, the sides evenly, feebly arcuate 

 from above, the apex very feebly sinuate throughout but only 

 margined laterally, the angles slightly obtuse and bluntly rounded, 

 the basal angles right and very slightly prominent, the punctures 

 coarse and somewhat sparse throughout the length medially, gradu- 

 ally still coarser but equally sparse laterally, becoming close and 

 smaller in the feeble sublateral basal impressions and near the 

 side margins; scutellum rather small, about as long as wide, 

 ogival ; elytra widest rather behind the middle, gradually some- 

 what acutely ogival behind, the sides broadly arcuate, becoming 

 more strongly rounded near the very obtusely subangulate humeri, 

 which are but little exposed basally, the surface impressed within 

 the humeral callus and in two or three shallow sutural grooves 

 posteriorly, rather coarsely, unevenly, sparsely punctured sutur- 

 ally, but little more coarsely though less sparsely laterally ; 

 abdomen densely, rugosely punctured medially. Length 1 1 . 3 

 mm. ; width 5.2 mm. ( 9 )• Utah (Chadbourne's Ranch), — H.

Form more slender, elongate-oval, polished, dark rufo-piceous through- 

 out ; head not closely punctured, very coarsely medially, less 

 coarsely toward the sides and apex ; prothorax transverse, nearly 

 one-half wider than long, the apex fully three-fourths as wide as 

 the base, subtruncate, being only just visibly though evenly sinuate, 

 the angles right but only slightly blunt, not in the least anteriorly 

 produced or prominent, the sides very feebly arcuate, becoming 

 slightly sinuate apically and straight or subsinuate near the basal 

 angles, which are right and not at all rounded ; surface finely, 

 very sparsely punctate medially, less finely and more closely 

 apically, very coarsely but sparsely at about lateral fourth, except 

 less coarsely and more closely at apex and in the basal impression 

 and also densely near the sides ; scutellum ogival, nearly as long 

 as wide; elytra d^) fully three-fourths longer than w^ide, gradu- 

 ally acutely ogival behind, the sides feebly arcuate, scarcely more 

 rounding at base, the humeral callus strong, the punctures strong 

 but sparse suturally, somewhat coarse but not much closer later- 

 ally, confused, the surface not impressed except feebly near the 

 suture at apex ; abdomen unusually coarsely punctate and not very 

 rugose, the punctures close but somewhat separated medially.

Form rather stout, larger, very convex, elongate-oval, highly polished, 

 castaneous in color; head coarsely, rather sparsely punctured 

 medially, less coarsely and rather closely anteriorly, the epistoma 

 deflexed, moderate, rounded ; prothorax somewhat less than one- 

 half wider than long, moderately narrowed from the base, the 

 sides feebly arcuate, becoming broadly and very slightly sinuate
