AMARIN.E 3 1 ? 



deep short incisure evident, the outer very feeble, rounded or sub- 

 oblique; elytra one-half longer than wide, equal in width to the pro- 

 thorax, very gradually rounded behind the middle, the subapical 

 sinus distinct; striae not definitely punctulate, moderate and 1 im- 

 pressed (cf ), or very fine and unimpressed (9 ), the scutellar long, 

 entire or interrupted, the seventh extremely fine and feeble; inter- 

 vals rather conspicuously convex (cf ), or perfectly flat ( 9 ) ; anterior 

 tarsi moderately dilated in the male, the abdominal segments each 

 with a small rounded discal impression near each side, especially in 

 the male. Length (cf 9 ) 6.3-7.2 mm.; width 2.7-3.0 mm. Utah

7 Form and size somewhat as in longula, black, with bronze lustre, 

 shining, the elytra feebly alutaceous in the female, elongate-suboval, 

 convex; under surface black, the legs obscure rufous; head distinctly 

 more than half as wide as the prothorax, the eyes large and rather 

 prominent, nearly as in scitula; antennae extending slightly behind 

 the thoracic base; prothorax relatively not large, the sides strongly 

 rounding anteriorly, subparallel and nearly straight in more than 

 basal half; apex feebly sinuate, with short blunt angles, the basal 

 angles somewhat acute, the puncture near the tip of the angle; im- 

 pressions very feeble, the foveal region with small sparse punctures; 

 inner fovea long, feebly impressed, its anterior part deep, the outer 

 very feeble, oblique; elytra one-half longer than wide, at the middle 

 of the distinctly arcuate sides nearly a fifth wider than the pro- 

 thorax probably much less in the male type, the sides very gradu- 

 ally rounding behind; striae rather deep and impunctate internally, 

 more shallow and minutely, closely punctulate externally, the scu- 

 tellar long; intervals nearly flat throughout. Length (9) 7.7-8.0 

 mm.; width 3.1-3.2 mm. California (San Francisco Bay). Three 

 examples afoveolata Hayw. 



Form less elongate, much smaller in size, more convex, polished, greenish- 

 black, the elytra scarcely less shining in the female; under surface 

 greenish-black; femora black, with feeble metallic lustre, the tibiae 

 and tarsi piceo-rufous; head smaller, though sensibly more than half 

 as wide as the prothorax, the eyes nearly as in the preceding; an- 

 tennae extending nearly to the thoracic base but with shorter joints, 

 especially toward tip; prothorax shorter, one-half wider than long, 

 otherwise somewhat similar in outline, the hind angles right, the 

 puncture near the tip; apex feebly sinuate with blunt angles; posterior 

 transverse impression distinct, the anterior obsolete; foveal region 

 impunctate, the foveae also wholly obsolete, except the short deep 

 discal line of the inner, the outer sometimes represented by a small 

 feeble point; elytra one-half longer than wide, only very slightly 

 wider than the prothorax, the arcuate sides gradually rounding be- 

 hind; striae rather fine, impunctate, the inner deep and abrupt, the 

 scutellar moderate, disintegrated; intervals feebly but sensibly con- 

 vex internally. Length (9) 6.3 mm.; width 2.5 mm. Utah
