extending inwardly along the base to the scutellum, and also with 

 a transverse pale fascia near apical third; epipleura and legs pale 

 flavate, the under surface black; head three-fourths as wide as the 

 prothorax, with well developed eyes, the shining sulci deep; antennae 

 slender, piceous, with paler basal joint, about as long as the elytra, 

 the medial joints between two and three times as long as wide; pro- 

 thorax transverse, nearly one-half wider than long, the sides rounded, 

 feebly oblique behind, becoming slightly sinuate at the right hind 

 angles; margins moderately reflexed; surface convex, punctate at 

 base, with very feeble impressions and fine stria; foveae rounded, very 

 deep, the carina distinct; elytra oblong, parabolic in apical two- 

 fifths, one-half longer than wide and two-fifths wider than the pro- 

 thorax, having two distinct punctate striae and a third shorter and 

 very feeble, the second not quite entire, the fifth feeble and oblique; 

 foveae near basal and apical third. Length (cf) 3.35 mm.; width 

 1.25 mm. California (Gilroy Hot Springs, Sta. Clara Co.).

Prothorax more nearly cordiform, the sides more sinuate basally, the 

 elytral striae in great part obsolete and, where visible, impunctate. . 2 



2 Prothorax about as long as wide and barely visibly wider than the 

 head. Body elongate, highly polished and smooth, piceo-rufous in 

 color, each elytron with a large triangular humeral pale spot, ex- 

 tending on the margin to basal third and, inwardly, enveloping the 

 scutellum, the humeral callus piceous, also with a pale fascia behind 

 apical third, which is gradually attenuated and bent backward to- 

 ward the suture; under surface pale piceous, the epipleura and legs 

 flavate; head with prominent eyes and moderate sulci; antennae 

 long, flavate, fully as long as the elytra, the medial joints fully three 

 times as long as wide; prothorax convex, rounded at the sides an- 

 teriorly, the sides moderately oblique from before the middle, be- 

 coming sinuate, parallel in basal sixth, the angles right and sharp; 

 impressions obsolete; stria very fine and greatly biabbreviated; 

 margins extremely finely reflexed; foveae large, smooth, moderately 

 deep, with a fine linear impression, the carina rather long and strong; 

 elytra ogival in apical third, fully one-half longer than wide and 

 four-fifths wider than the prothorax; sutural stria alone evident and 

 this only behind, the eighth deeply impressed as usual; foveae very 

 small, at two and five sevenths. Length (cf) 3.6 mm.; width 1.2 

 mm. California (Cloverdale, Sonoma Co.) hilare n. sp. 



Prothorax wider than long and distinctly wider than the head 3 



3 Prothorax at base about as wide as at apex. Form narrowly oblong, 

 convex, polished, deep black, with feeble greenish or aeneous lustre, 

 each elytron with a large, transversely rounded external pale spot 

 behind the humeri and a transverse fascia at apical third, extending 

 to inner third; under surface black, the legs rufo-piceous; head four- 

 fifths as wide as the prothorax, the antennae black, piceous at base, 

 almost as long as the elytra, the medial joints between two and three 

 times as long as wide; prothorax two-fifths wider than long, the sides 

 rounded from apex to basal fourth, becoming parallel in basal fifth, 

 the angles very sharp; surface convex, the margins moderately re-
