17 — Pronotum evenly convex, not at all tumid at the middle before the basal impres- 

 sion, the surface sloping steeply to the impression, which is very fine ; body 

 narrowly oblong-oval, rather strongly convex, shining, black, the elytra feebly 

 picescent, the legs and antennae dark rufo-testaceous ; pubescence short but coarse 

 and rather abundant ; antennae slender and rather more than half as long as the 

 body, the basal joint well developed and nearly as long as the next three com- 

 bined, the club rather small and narrow, with its two basal joints but slightly 

 transverse ; prothorax slightly transverse, evenly and strongly convex, fully as 

 wide as the elytra, the sides subparallel, broadly, feebly arcuate, more convergent 

 at base and apex, the latter but little the narrower ; punctures only moderately 

 coarse but stro-ig and somewhat close-set; elytra barely three-fifths longer than 

 wide, obtusely rounded behind, parallel, convex, the punctures strong, close-set 

 and distinctly sublinear in arrangement. Length 1.4 mm.; width 0.6 mm.

Pronotum more or less feebly, though perceptibly, tumid at the middle before the 

 basal impression ; body never entirely black 18 



18 — Elytral punctures conspicuously coarse and well separated 1 9 



Elytral punctures not very coarse, though always strong, and very distinct, generally 

 less sparse 21 



19 — Sides of the prothorax with a broadly rounded feeble sinus just behind the mid- 

 dle, a little more rounded but scarcely prominent near basal fourth, becoming 

 apparently even and broadly arcuate throughout \\\ puella 20 



Sides of the prothorax strongly converging and broadly arcuate from basal fourth to 

 apex with a very short feeble rounded sinus just before the slight prominence at 

 basal fourth, from which point to the base they are strongly convergent ; body 

 oblong-oval, moderately stout and convex, shining, black, the elytra, legs and 

 antennse piceo-rufous ; pubescence very short and moderately abundant ; antennae 

 well developed, the club rather stout, with its two basal joints strongly transverse, 

 prothorax fully one-half wider than long, the apex very much narrower than 

 the base, the punctures not very coarse but deep and only moderately close ; 

 elytra scarcely more than one-half longer than wide, fully a fourth wider than the 

 prothorax, parallel, obtusely rounded in apical two-fifths, the punctures quite 

 coarse and moderately close-set. Length 1.3 mm.; width 0.55 mm. California

20 — Body moderately stout, elongate-oval and convex, shining, blackish, the elytra, 

 legs and antennae testaceous ; pubescence short and sparse ; antennae rather long 

 and slender, nearly half as long as the body, the club moderately wide, rather 

 long and loose, its two basal joints transversely obtrapezoidal, the eighth joint 

 subquadrate and but slightly narrower than the seventh ; prothorax well developed 

 and transverse, fully two-fifths wider than long, narrowed only slightly in basal 

 fourth, the apex but little narrower than the base ; surface almost evenly convex, 

 finely but strongly, somewhat closely punctate ; elytra parallel and broadly 

 arcuate at the sides, obtusely rounded at apex, three-fifths longer than wide and 

 but little wider than the prothorax, the punctures coarse and moderately sparse. 

 Length 1. 65 mm. ; width 0.7 mm. California (Humboldt Co.).
