basally; inner subbasal striole very feeble, the outer deep, oblique 

 and foveiform; elytra rather short, two-fifths longer than wide, 

 barely wider than the prothorax; striae fine, impunctate, the scutel- 

 lar long, the foveae of the eighth narrowly though completely inter- 

 rupted medially; intervals nearly flat throughout, sometimes with 

 alternate slight irregularity. Length (cf 9 ) 8.0-8.6 mm.; width 

 3.4-3.65 mm. California (Siskiyou Co.). Four examples. 



shastanica n. sp. 



Form more elongate-oval, convex, shining, black, with barely a trace of 

 metallic lustre, the elytra (9) strongly micro-reticulate though 

 rather shining; under surface black, without trace of metallic lustre, 

 the legs piceous in the type; head barely more than half as wide as 

 the prothorax, with nearly flat eyes and strong foveiform strioles; 

 antennae slender, black, the first two joints and basal part of the third 

 rufescent; prothorax much longer than in the preceding, barely 

 one-half wider than long, the deeply sinuate apex much narrower 

 than the base, the angles obtusely rounded at tip; sides feebly, sub- 

 evenly rounded, becoming parallel at base, the angles right; surface 

 with very indistinct impressions, the outer subbasal fovea rounded, 

 moderately deep, the puncture in the hind angles coarse; elytra 

 fully one-half longer than wide, gradually ogival in rather more than 

 apical third, not distinctly wider than the prothorax, the sinus 

 rather deep; striae somewhat fine but groove-like, not punctate, the 

 scutellar long, free at both ends; lateral ocellate series widely separ- 

 ated but not definitely interrupted medially; intervals feebly convex, 

 somewhat irregular; striae coarser, with convex intervals on the de- 

 clivity. Length (9 ) 9-Q mm.; width 3.8 mm. Oregon (Clackamas 

 Co.) , Kermack semota n. sp. 



8 Eyes larger but only moderately prominent, as in most of the pre- 

 ceding species 9 



Eyes smaller but strongly convex and prominent, the head evidently still 

 smaller IO 



9 Body elongate-oval, rather convex, shining and more or less bronzed 

 above, the under surface and legs deep and uniform black through- 

 out, without metallic lustre of any kind; elytra scarcely less shining 

 in the female, though micro-reticulate in both sexes; head very nearly 

 half as wide as the prothorax, the eyes only feebly convex, the stri- 

 oles moderate, fine; antennae extending to the thoracic base, black, 

 the first joint rufous, the second piceous, the third carinate basally; 

 prothorax one-half wider than long to slightly more; apex deeply 

 sinuate, much narrower than the base, with prominent though 

 bluntly rounded angles; sides finely reflexed, evenly and moderately 

 converging and feebly arcuate from base to apex; inner subbasal 

 impression short, feebly impressed and sublinear, the outer small, 

 almost obsolete; transverse impressions feeble though evident; ely- 

 tra (cT) more or ( 9 ) less than one-half longer than wide, but slightly 

 wider than the prothorax, obtusely rounded in barely apical third, 

 the sinus wide and shallow; striae fine, the scutellar long; lateral 

 series rather narrowly interrupted; intervals very feebly convex.
