clothed with suberect fuscous hairs; head and prothorax extremely 

 densely punctate, the latter sparsely pilose, nearly as long as wide, 

 rounded at the sides, narrowed posteriorly, with an obsolete median 

 line and a posterior sublateral callous spot smooth; elytra sparsely 

 punctate, the punctures basally large, fine posteriorly; femora 

 strongly incrassate, the tibiae with long sparse hairs. Length 12.0- 

 13.75 mm. California (Tejon). [Callidiiim obscurum Lee.,

Form rather broader, much larger, piceous-black throughout, slightly 

 shining; head very densely, granularly punctate, the eyes far from 

 divided; antennae (cf) four-fifths as long as the body, slender, the 

 second joint nearly twice as long as wide and one-half as long as the 

 third, last joint shorter than the tenth, simple, slender; prothorax 

 fully as long as wide, parallel, with broadly and subevenly rounded 

 sides, more converging very near the base, which is but little nar- 

 rower than the apex; surface not coarsely, very densely and granu- 

 larly punctate, becoming loosely and more coarsely so near the apex 

 and very densely and granularly rugose on the flanks and beneath, 

 the median line narrowly smooth and but feebly tumescent basally, 

 the surface also broadly and very feebly tumescent near lateral 

 fourth at or just in front of the middle, the summit subimpunctate 

 and shining; basal smooth spots wanting; hairs erect, rather long 

 but very sparse; scutellum extremely minutely and densely punc- 

 tate and closely pubescent; elytra long, parallel, with straight 

 sides, rapidly very obtusely and almost conjointly rounded at apex, 

 two and one-half times as long as wide and one-half wider than the 

 prothorax; surface subdepressed, very finely not densely punctate, 

 scarcely less finely so basally, each puncture with a rather coarse 

 but short suberect blackish hair; sutural angles narrowly rounded; 

 legs long, the femora strongly clavate; abdomen smooth and polished, 

 extremely minutely and remotely punctulate, the fifth segment very 

 short, broadly sinuato-truncate. Length (cf ) 15.5 mm.; width 4.5 

 mm. California (San Diego) grandis n. sp. 



5 Parallel, notably depressed, dark smoky-brown, dull in lustre, 

 minutely, extremely closely punctulate, more sparsely on the elytra, 

 which are less dull, except in an opaque region behind a nubilously 

 pallid area occupying not quite basal half of each and not involving 

 the base or a gradually narrowing sutural region from the base, 

 the said opaque area extending posteriorly to very near the apex; 

 pronotum even, without callous spots but with a narrow smooth line 

 broadening basally, the sides broadly and obtusely angulate at the 

 middle; base much narrower than the apex; elytra much wider than 

 the prothorax; pubescence throughout extremely short, close, not at 

 all erect on the prothorax; thighs strongly clavate apically but 

 scarcely more so in the male than in the female. Length (cf, 9) 

 6.8-8.0 mm.; width 1.8-2.4 mm. Massachusetts and Colorado to 

 southern Alaska. [Callidiiim dimidiatum Kirby, Fn. Bor.-Am.,
