136 CASEY 



equally coarse and still more unevenly distributed laterally, the 

 bead moderately fine, almost straight, not curved at base ; scutel- 

 lum smaller than in any other species observed ; elytra much less 

 than one-half longer than wide, more oval, the sides rounding and 

 converging behind the middle to the more obtusely angulate apex, 

 the surface similarly rugose but still less coarsely, sparsely punc- 

 tate ; prosternum opaque, finely, not conspicuously punctate, the 

 process abnormally short, broadly rounded, moderately con- 

 stricted, very sparsely punctate, unmargined except very finely 

 at the sides toward base ; hind femora rather closely, some- 

 what strongly punctured, the abdomen unusually closely and 

 strongly so. Length 9.8 mm; width 5. 3 mm. Vancouver Island,

8 Anterior canthus about as prominent as the posterior 9 



Anterior canthus much less prominent than the posterior n 



9 Body oblong in form, convex, polished throughout, deep black; 



head rather finely, subevenly and loosely punctate, the sinus rather 

 deeply parabolic, the lobes rounded, unimpressed, the anterior 

 canthus strongly rounded, a little more prominent than the pos- 

 terior; prothorax four-fifths wider than long, the sides broadly 

 rounded and moderately converging anteriorly, becoming nearly 

 parallel toward base, the apex evenly and moderately sinuate, two- 

 thirds as wide as the base, the angles deflexed, right and but little 

 rounded, the base broadly, feebly bisinuate, with the angles rather 

 abruptly and moderately produced ; surface very finely, sparsely 

 punctate, becoming moderately coarsely, not very closely so later- 

 ally, except anteriorly where they are still rather fine and sparse, 

 the bead fine ; scutellum not very transverse, moderate, somewhat 

 obtusely angulate ; elytra one-half longer than wide, the sides 

 parallel and nearly straight to apical two-fifths, then strongly 

 rounded, becoming straight to the obtusely angulate and promi- 

 nent tip ; surface smooth, finely, densely rugose behind, the punc- 

 tures moderately fine, rather sparse ; prosternum densely punctate 

 and rugulose, the process polished and sparsely punctulate, 

 rounded at tip, strongly constricted ; hind femora and abdomen 

 strongly but not very coarsely punctate, the latter the more closely.
