Elytral vestiture long, shaggy and very conspicuous 4 



3 Body rather narrowly oblong or subelongate, convex., deep black, 

 the antennae black, the legs piceous distally ; surface rather shin- 

 ing, the elytral setae small and not very conspicuous ; head well 

 developed, rather finely and sparsely punctate, the sinus rather 

 deep, sharply parabolic, the lobes broady rounded, the anterior 

 canthus angularly rounded, as prominent as the posterior ; pro- 

 thorax transverse, nearly three-fourths wider than long, the sides 

 broadly rounded, more converging anteriorly, becoming almost 

 parallel toward base, the apex moderately sinuate, fully three- 

 fifths as wide as the base, with the angles evidently rounded ; 

 surface very finely, sparsely punctate, becoming gradually rather 

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

 moderate ; elytra one-half longer than wide, parallel, very obtusely 

 and broadly, parabolically rounded behind, generally almost 

 smooth but sometimes rugose, with obsolete indications of longi- 

 tudinal tumescent lines occasionally, strongly, rather closely 

 punctate, more coarsely and still more closely so laterally and 

 also apically, where the surface is more opaque ; prosternum 

 finely, rugosely sculptured, the process polished and more 

 sparsely and strongly punctate, strongly margined at the sides 

 but immarginate at tip ; hind femora strongly though very 

 sparsely punctate, the abdomen minutely, remotely so, more 

 strongly toward the sides; tarsi slender. Length 10.0-10.3 mm. ; 

 width 4.8-5.0 mm. Idaho (Coeur d'Alene). One specimen is 

 labeled " Cal." but probably in error setosa Csy. 



Body somewhat stouter and more abbreviated, deep black, moderately 

 shining, the bristling vestiture distinct, fulvous; head rather 

 coarsely and densely punctured toward the suture, coarsely 

 apically and sparsely and finely from before the eyes to the base, 

 the sinus broad, parabolic, the anterior canthus rather obtusely 

 pointed, much less prominent than the posterior; oblique sides 

 feebly emarginate at the ends of the oblique sutures ; prothorax 

 more transverse, nearly four-fifths wider than long, the sides sub- 

 evenly and moderately arcuate throughout, becoming parallel 

 only near the base ; apex broadly sinuate, two-thirds as wide as 

 the base, with the angles right and but slightly blunt ; surface 

 finely, sparsely punctate, becoming broadly rather coarsely but 

 not much more closely so toward the sides, the bead rather fine, 

 the base broadly, evenly bisinuate ; scutellum rather small, trans- 

 versely triangular; elytra parallel, very broadly and obtusely 

 rounded in apical third, two-fifths longer than wide, nearly 

 smooth, finely, remotely punctate, more coarsely but shallowly 

 and not much less sparsely so toward the sides, subopaque pos- 

 teriorly; prosternum rather strongly punctate, the process broad, 

 subparallel, unmargined except finely along the coxae ; hind 

 femora and abdomen rather finely but more or less strongly, 

 sparsely punctate. Length 10.0 mm. ; width 5.2 mm. Utah 

 (Clear Lake), H. F. Wickham obtusa n. sp.
