134 CASEY 



strongly produced ; surface strongly convex, sparsely but unusually 

 coarsely punctate, gradually closely though unequally and still 

 more coarsely so laterally, the bead moderately thick ; scutellum 

 moderate ; elytra scarcely one-half longer than wide, equal in 

 width to the prothorax, the sides straight and parallel, rather 

 rapidly converging and rounded in apical two-fifths, oblique and 

 straighter toward the rather acute tip ; surface very coarsely, 

 deeply and rather closely punctate and very strongly rugose 

 throughout ; prosternum rather strongly, closely punctate, the 

 process finely so, distinctly constricted, rather acutely rounded at 

 apex and unmargined ; hind femora rather coarsely and conspicu- 

 ously, though somewhat sparsely, punctured, the abdomen but little 

 less coarsely and sparsely, strongly so. Length 9.4 mm. ; width 

 5.0 mm. (c?). Washington State, — exact locality unrecorded. 



sculptipennis n. sp. 



Sides of the prothorax converging from the base. . 3 



3 — Prosternal process margined throughout 4 



Prosternal process not margined, except feebly toward base 5 



4 — Body very evenly subelliptic in form, convex, shining; head 



strongly, rather loosely punctate, the sinus moderate in width, 

 unvisually deep, angulate, the lobes broadly rounded, more or less 

 strongly impressed within the margin, the anterior canthus 

 obliquely and somewhat narrowly rounded, a little more promi- 

 nent than the posterior ; prothorax fully three-fourths wider than 

 long, the sides almost evenly and broadly rounded from base to 

 apex, the latter rather shallowly sinuate, with the bottom of the 

 sinus transverse, barely three-fifths as wide as the base, the angles 

 deflexed and somewhat obtuse but only very narrowly rounded ; 

 base broadly bisinuate, the angles somewhat produced and acute ; 

 surface rather finely and sparsely though very distinctly punctate, 

 gradually coarsely and rather closely so laterally, the bead fine ; 

 scutellum rather small, not very transverse, sharply triangular; 

 elytra as wide as the prothorax, fully one-half longer than wide, 

 the sides parallel and just visibly arcuate, rounding and converg- 

 ing in apical two-fifths, the sides becoming nearly straight toward 

 the rather acutely angular tip ; surface rugose to nearly smooth, 

 moderately coarsely, rather sparsely punctate ; prosternum pol- 

 ished, strongly, rather closely punctate, the process distinctly con- 

 stricted, the marginal bead strong throughout ; hind femora with 

 moderate and rather strong but sparse punctures, those of the abdo- 

 men similar though closer. Length 11.0-11.2 mm.; width 5.7 

 mm. Washington State (Leavenworth), — H. F. Wickham. 



regularis n. sp. 



Body less evenly elliptic, oblong-oval, sometimes feebly inflated pos- 

 teriorly, shining ; head rather coarsely and closely punctate, the 

 sinus nearly as in regularis^ the lobes more narrowly rounded, 

 more broadly and less linearly impressed, the anterior canthus 

 nearly similar but more rounded; prothorax barely three-fourths
