PLATYNINiE 6 1 



Sides of the prothorax less arcuate before the middle; legs, tarsi and 

 antennae distinctly less slender than in impictus; size larger, the 

 outline stouter, similarly convex and shining, black, without metallic 

 lustre; femora and tibiae uniform rufo-piceous, the tarsi rather 

 darker; head not quite so large but with large and prominent 

 eyes, the front not bifoveate between them; antennae similar in 

 coloration, rather more than half as. long as the body, the third 

 joint much shorter than the fourth; prothorax a fourth wider than 

 long, very finely reflexed at the sides; base strongly arcuate and 

 oblique at the sides; surface smooth, the impressions obsolete, the 

 stria fine, entire; fovese smooth, sharply and deeply impressed, 

 lineate as usual, traceable to the middle, the anterior part very 

 feeble and outwardly oblique; elytra three-fifths longer than wide, 

 four-fifths wider than the prothorax, the sides not very rapidly 

 more rounding at base, parallel and feebly arcuate; striae and 

 intervals about as in impictus; anterior male tarsi very moderately 

 dilated. Length (cT' 9) 7.8-8.0 mm.; width 2.85-3.0 mm. Cali- 

 fornia (Los Angeles to Siskiyou) calif ornicus Dej. 



Sides of the prothorax somewhat as in calijornicus and feebly arcuate, 

 though the greatest width is similarly before the middle; basal 

 angles obtuse, with the tips almost similarly prominent; size 

 slightly smaller, narrower and less convex, polished black, with 

 dark green metallic lustre, scarcely visible on the elytra; under 

 surface piceous-black, the legs dark rufous; head barely at all longer 

 than wide, nearly four-fifths as wide as the prothorax, with large 

 and prominent eyes; antennae more than half as long as the body, 

 black, with piceo-testaceous basal joint, the third joint much 

 shorter than the fourth; prothorax much narrower, very little wider 

 than long, the sides finely reflexed; base fully as wide as the feebly 

 sinuate apex; impressions subobsolete, the fine stria impressed; 

 foveae nearly smooth, linear and very deep; elytra three-fifths 

 longer than wide, not quite twice as wide as the prothorax, parallel, 

 gradually subevenly rounded behind, with distinct sinus; striae 

 fine, sharply grooved, smooth; intervals flat, shining, the third 

 with five rather small but well defined punctures; met-episterna 

 twice as long as wide; anterior male tarsi feebly but distinctly 

 dilated. Length (cf) 7.2 mm.; width 2.6 mm. Nevada (Battle 

 Mts.) viimulus n. sp. 



12 — Legs black. Body very small, moderately convex, polished black 

 throughout, without trace of metaljic lustre; head slightly though 

 evidently narrower than the prothorax, only slightly elongate, with 

 notably prominent eyes; palpi moderate, the fourth joint much 

 longer than the third; antennae more than half as long as the body, 

 the third and fourth joints equal; prothorax a fifth wider than long, 

 the sides rounded anteriorly, oblique and straight basally, finely 

 reflexed, very little more so basally, the angles very obtuse, the 

 tips obtusely blunt; base arcuate, as wide as the very moderately 

 sinuate apex; anterior impression angulate and rather deep medi- 

 ally; stria fine but deep, abbreviated at apex; foveae small, mooth, 

 oblong, not prolonged; between them and each side at base there
