Coleopterological Xotices, VI. 635 



fully two-fifths as long as the body, the basal joint not paler. Proihorax 

 scarcely as wide as the head and not quite as long as wide, strongly but not 

 very coarsely or densely granulato-punctate, the surface shining through the 

 vestiture; sides strongly rounded anteriorly, thence distinctly convergent and 

 feebly sinuate to the basal margin, which is not dilated; apical constriction 

 distinct, the lobe extremely short ; canalieulation fine but very deep and dis- 

 tinct; lateral oblicjue impressions feeble. Elytra twice as wide as the pro- 

 thorax, distinctly more than twice as long as wide, parabolic in apical fourth; 

 humeri transversely, broadly rounded to the prothorax, the intrahumeral im- 

 pression short, basal and very distinct; disk strongly but only moderately 

 coarsely punctate, giving a subrugose appearance, the interspaces not distinctly 

 punctulate. Under surface finely, densely punctate and pubescent. Length 

 6.5-8.0 mm.; width 1.8-2.-2 mm. 



Indiana. 



In its larger, more globose and less distant e3'es, shorter, less 

 prominent tempora and generally more shining snrface, this 

 species departs from the common t3'pe of the Pacific coast and 

 approaches mellyi. It dilTers from mellyi in the small nuclei of 

 pubescence scattered irregularly and indefinably over the elytra, 

 and in the smaller, more strongly and coarsely sculptured and 

 more deeply canaliculate prothorax. Four specimens, with very 

 feeble, sexual characters. 



S. impressicollis. — Black and moderately stout, the elytra shining 

 through the vestiture, which is rather sparse except in the condensed spots; 

 legs and antennae black throughout. Head densely punctato-rugose and dull, 

 the vestiture dense ; eyes moderate, separated by distinctly more than twice 

 their own width, the tempora fully as prominent as the eyes and about one- 

 half as long; antennse moderately slender, about two-fifths as long as the body. 

 Prothorax as long as wide, rounded on the sides anteriorly, sinuate thence to 

 the basal margin, which is scarcely dilated and defined throughout dorsally by 

 a distinct groove; apical constriction fine, distinct; canalieulation fine, deep, 

 impressed; lateral oblique impressions strong; sculpture rugose. Elytra 

 slightly more than tAvice as wide as the prothorax, a little more than twice as 

 long as wide, quite perceptibly wider to apical fourth, then parabolically 

 roiinded, narrowly and gradually dehiscent behind, the sutural angles obtusely 

 rounded; humeri broadly, evenly rounded, the impression feeble; punctures 

 coarse, close, the surface subrugose; interspaces shining and not distinctly 

 punctulate. Abdomen minutely, extremely densely punctate and pubescent. 

 Length 6.3 mm. ; width 2.0 mm. 



California (Hoopa Yal., Humboldt Co.). 



The single specimen is a female, and, if my memory serves, was 

 taken ver3' nearl}- or quite at the same time and place as the single 

 male of indutus, so that for some time I considered them to be
