294 MEMOIRS ON THE COLEOPTERA 



face and femora black, the tibiae and tarsi obscure rufous; elytra (9 ) 

 only feebly alutaceous; head scarcely more than half as wide as the 

 prothorax, the eyes only moderately prominent, the strioles rather 

 short, coarsely impressed, subparallel; antennae piceous-black, the 

 three basal joints obscure testaceous; prothorax three-fourths wider 

 than long, the sides broadly arcuate, becoming parallel in about 

 basal half; apex fully three-fourths as wide as the base; feebly sinuato- 

 truncate, with bluntly rounded angles; basal angles right and only 

 slightly blunt; base feebly sinuate at each side; impressions subob- 

 solete, the stria moderate, much abbreviated; foveal area impunc- 

 tate; inner fovea fine, feeble, long and linear, the outer linear, pos- 

 teriorly oblique outwardly; elytra one-half longer than wide, at the 

 middle distinctly wider than the prothorax, gradually convergently 

 rounded behind the middle; striae very fine, feebly subpunctulate 

 laterally, the scutellar long, oblique, not free at tip; intervals broadly, 

 feebly convex, the convexity especially feeble toward the sides; tarsi 

 long, slender. Length (9) 9.3 mm.; width 3.8 mm. California 

 (San Clemente Island) perspecta n. sp. 



Lateral series with the punctures more widely, irregularly spaced medi- 

 ally, but not definitely interrupted; antennae ferruginous, sometimes 

 very feebly infuscate, excepting the four basal jeints 3 



3 Form rather.stout, larger in size, shining, black, with aeneous lustre, 

 sometimes decidedly blue and rarely greenish; femora nearly black, 

 the tibiae and tarsi obscure rufous; head half as wide as the prothorax, 

 with well developed but only moderately prominent eyes; prothorax 

 three-fifths to two-thirds wider than long, the sides parallel, feebly 

 arcuate, more so and converging anteriorly; apex broad, feebly sinu- 

 ate, the angles blunt; basal angles much more than right though not 

 rounded; margins abruptly and strongly but not broadly reflexed; 

 impressions obsolete; foveal punctures numerous to almost wanting; 

 inner fovea long, linear, the outer rounded, feebly impressed, dis- 

 tant from the base; elytra nearly one-half longer than wide, about 

 equal in width to the prothorax, rapidly and broadly rounded be- 

 hind; striae not very fine, impunctate, groove-like, sometimes im- 

 pressed, the scutellar long, oblique, narrowly free at tip and generally 

 widely free at base; anterior tarsi very broadly dilated (cf ); elytra 

 (9) feebly to densely alutaceous; under surface punctureless. 

 Length (c?) 8.8-10.0, (9) 9.8-11.0 mm.; width (cf) 3-75-4-3, (9) 

 4.4-4.9 mm. California (middle coast regions). Said to occur 

 also northwardly as far as Sitka, Alaska. [Am. ccerulea and com- 

 pacta Mots.] "... .insignis Dej. 



Form narrower, the size notably smaller; coloration almost similar, ex- 

 cept that the legs are uniformly rufous throughout and the. antennae 

 very pale ferruginous; head slightly more than half as wide as the 

 prothorax, the eyes rather more prominent than in insignis; pro- 

 thorax almost similar throughout, except that it is relatively not 

 quite so large; elytra fully one-half longer than wide, a little less ( 9 ), 

 more gradually ogival behind than in insignis and, at the middle of 

 the more arcuate sides, very distinctly wider than the prothorax; 

 striae finer, impunctate, the scutellar very long, nearly as in insignis;
