AMERICAN COMPONENTS OF THE TENTYRIIN^ 419 



13 — Form stout, suboblong-oval, convex, shining, glabrous, dark 

 brownish-testaceous in color; head coarsely, very regularly and 

 rather closely punctured, the punctures separated by nearly twice 

 their own diameters throughout though smaller anteriorly ; pro- 

 thorax nearly one-half wider than long, the apex fully three-fourths 

 as wide as the base, evenly and very distinctly sinuate, the angles 

 right, not blunt and very distinct, in fact subprominent, the sides 

 feebly arcuate, becoming straight for a short distance anteriorly 

 and broadly sinuate toward base, the basal angles broadly though 

 feebly everted, acute and prominent, the punctures rather coarse 

 and sparse, becoming very coarse but well separated laterally, 

 except in the feeble basal impressions, where they are less coarse 

 and closer and also on the flanks, where they are rather crowded ; 

 scutellum moderate ; elytra parallel, with broadly and evenly 

 arcuate sides to the base, gradually rather obtusely ogival poste- 

 riorly, the humeral callus long and strong, the surface broadly, 

 strongly impressed at the suture near the apex, rather coarsely, 

 sparsely punctate, almost similarly so laterally, except that the 

 punctures become more perforate, less impressed and somewhat 

 shallower; abdomen finely, very densely punctate and rather dull. 

 Length ii.o mm.; width 4.9 mm. Arizona (Cochise Co., — 

 San Bernardino Ranch), — F. H. Snow angulata n. sp. 



13 — Body elongate, fusiform, moderately stout, convex, the feebly 

 fulvous hairs longer than usual and rather conspicuous though 

 sparse, castaneous, the elytra paler and more testaceous ; head 

 not very coarsely and very unevenly punctured, very sparsely 

 medially, closely anteriorly and toward the eyes ; prothorax less 

 transverse, only about a third wider than long, the apex fully 

 three-fourths as wide as the base, evenly and very distinctly sinu- 

 ate, with the angles somewhat acute, not blunt and decidedly 

 prominent though not prolonged, the sides very feebly, evenly 

 arcuate, scarcely becoming straight near the basal angles though 

 distinctly sinuate behind the apical, the surface feebly, evenl}^ 

 convex transversely, finely, sparsely punctate, gradually coarsely 

 and less sparsely so laterally, becoming less coarsely toward and 

 in the scarcely visible basal impressions and smaller and crowded 

 near the sides ; scutellum moderate, nearly as long as wide, flat 

 and ogival ; elytra rather elongate, very gradually and arcuately 

 narrowed and acute posteriorly, the sides broadly arcuate, but 

 little more strongly so basally, where the hun'ieral callus is strong 

 and not much elongated, the surface distinctly impressed along 

 the suture posteriorly, very finely, remotely punctured throughout, 

 but little less sparsely toward the sides ; abdomen moderately 

 finely, densely but deeply punctate and dull, the basal segment, 

 as usual, less densely, more coarsely so and more shining. 

 Length 11.5 mm.; width 4.72 mm. California (southern).
