AMARIN^E 275 



uate, with rather blunt angles; basal angles more than right but not 

 rounded; impressions obsolete; punctures of the foveal region rather 

 small and numerous; inner fovea long, broadly impressed, linear, 

 the outer feeble to obsolete; elytra slightly less than one-half longer 

 than wide, gradually ogival behind, rather distinctly wider than the 

 prothorax, with parallel and broadly arcuate sides; striae fine but 

 sharply defined, slightly impressed in the male, the seventh very fine 

 and feeble, subdisintegrated, the scutellar very short to completely 

 wanting; intervals feebly convex to flat. Length (cf 9 ) 6.0-6.2 

 mm.; width 2.4-2.6 mm. California (Humboldt Co. Redwood 

 Creek and Hoopa Valley). Four examples hilaris n. sp. 



Body parallel, elongate, convex, polished, rather bright bronze in lustre, 

 the female elytra evidently alutaceous; under surface black, the legs 

 rufous; head nearly as in the preceding, the eyes prominent; strioles 

 almost parallel; antennae extending but slightly behind the thoracic 

 base, piceous, the first three joints testaceous; prothorax never much 

 over a third wider than long, the sides parallel, gradually rounding 

 apically, the basal angles barely more than right, usually not blunt; 

 apex nearly as in the preceding, feebly though evidently sinuate; 

 impressions obsolete; punctures of the foveal region fine, few in 

 number and sparsely scattered; inner fovea long, broadly impressed 

 and linear, the outer more rounded, evident and near the basal mar- 

 gin; elytra almost one-half longer than wide, barely visibly (cf ) or 

 slightly ( 9 ) wider than the prothorax, rapidly and obtusely ogival 

 behind; striae very fine, similar in the sexes, the scutellar long but 

 more or less disintegrated, free at both ends; intervals flat in both 

 sexes; seventh stria very feeble. Length (cT 9 ) 6.4-7.0 mm.; width 

 2.6-2.8 mm. Oregon (Columbia River Valley), Shantz. Three 

 specimens evanida n. sp. 



Body very narrow and elongate, convex, polished, black, with barely 

 perceptible metallic lustre; under surface black, the legs obscure 

 rufous, the femora blackish ; head two-thirds as wide as the prothorax, 

 with rather large and prominent eyes and coarse deep oblique stri- 

 oles; antennae long and slender, extending rather far behind the tho- 

 racic base, fuscous, gradually testaceous basally; prothorax a third 

 to two-fifths wider than long, the parallel sides gradually a little 

 more rounding anteriorly, narrowly but strongly reflexed as usual, 

 the basal angles slightly more than right, not rounded; apex ex- 

 tremely feebly sinuate, with broadly blunt angles; impressions obso- 

 lete, the stria fine; punctures of the foveal region small, moderately 

 numerous; inner fovea irregularly linear, feeble, the outer obsolete 

 or very nearly; elytra about one-half longer than wide, gradually 

 ogival behind, rather distinctly wider than the prothorax; striae very 

 fine, the seventh nearly obsolete, the scutellar wanting or vestigial; 

 intervals flat. Length (cf) 5.8-6.3 mm.; width 2.35-2.4 mm. Cali- 

 fornia (Siskiyou Co.), Koebele. Three specimens. . angustior n. sp. 



Although feeble lineiform punctulation, or perhaps more cor- 

 rectly comminution, of the lateral striae is frequently observable,
