74 MEMOIRS ON THE COLEOPTERA 



mm.; width 1.8-2.25 mm - California (San Diego the type locality 

 and coast regions north of San Francisco), also Oregon (Corval- 

 lis). Sixteen examples striola Lee. 



Body narrower and more depressed, similarly black, with testaceous 

 legs, but with the elytra not black but uniform castaneous, the pos- 

 terior fascia nubilously paler; head rather well developed though 

 with less prominent eyes, four-fifths as wide as the prothorax but 

 more evidently narrower than an elytron; antennae nearly similar 

 but more slender; prothorax smaller, nearly one-half wider than 

 long, the evenly rounded sides abruptly straight and parallel in 

 nearly basal fifth, the angles right; surface as in striola but less con- 

 vex and with the side margins more finely reflexed; elytra parallel, 

 narrower, three-fifths longer than wide, fully one-half wider than 

 the prothorax, the striae as in striola but with the punctures smaller 

 and more close-set, the foveae near basal and apical third. Length 

 (cf 9 ) 4.7-5.6 mm.; width 1.8-2.0 mm. California (Dunsmuir, 

 Siskiyou Co. Wickham; also near Mt. Diablo). Six examples. 



shastanicum n. sp. 



55 Form oblong-suboval, rather convex, shining, black, the posterior 

 fascia but slightly bioblique and more or less interrupted at the su- 

 ture; elytra sometimes dark castaneous; under surface black, the 

 legs dark rufous, the femora blackish with pale tip; head moderate, 

 . distinctly narrower than an elytron; antennae slender, three-fourths 

 as long as the elytra, blackish, pale at base, the medial joints not 

 quite three times as long as wide; prothorax two-fifths to one-half 

 wider than long, in general outline as in the preceding species; sur- 

 face depressed and punctulate at base, the anterior impression dis- 

 tinct; foveae very deep, sublinear, usually more abrupt externally 

 than internally, the carina distinct and strongly elevated; elytra 

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

 thorax, the striae moderate, not much impressed, gradually disap- 

 pearing near the apex, the punctures not very coarse and well sep- 

 arated, closer in the two sutural series; foveae near basal third and 

 apical fourth. Length (cf 9 ) 4.5-5.3 mm.; width 1.75-1.9 mm. 

 New Mexico, Colorado (Boulder Co.), Utah (southwestern) and 

 Arizona (Tugson and other parts). Twelve specimens. 



consanguineum Hayw. 



Form more elongate, moderately convex, piceous-black, shining, the 

 elytra pale flavo-testaceous in the type, with. the bioblique posterior 

 fascia broadly interrupted at the suture and rendered more evident 

 by a darker shading bordering it anteriorly; under surface pale 

 piceous, the legs testaceous; head rather small, much narrower than 

 an elytron, the antennae slender, in great part pale; prothorax two- 

 fifths wider than long, the sides inflated and strongly arcuate, rather 

 abruptly straight and parallel in nearly basal sixth, the angles right; 

 surface barely at all depressed medially at base, the anterior impres- 

 sion moderate, the stria only visible between the impressions; foveae 

 deeply impressed, sublinear at the bottom, the carina distinct; side 

 margins more broadly reflexed than in any other of this section; 

 elytra more elongate, nearly two-thirds longer than wide, parallel,
