66 — Pronotum black, sometimes with the sides paler, minutely, sparsely and incon- 

 spicuously punctulate, the sides not quite continuous, moderately convergent, 

 evenly and rather strongly arcuate ; elytra black, finely but very clearly, evenly 

 and not very closely punctate ; legs red. Length 1.9 mm.; width 1.4 mm. 

 Oregon — Mr. Wickham caurin us Horn 



Pronotum pale testaceous, with a parabolic and frequently somewhat ill-defined median 

 black spot at the base, extending almost to the apical margin, the sides subcon- 

 tinuous with those of the elytra, convergent and rather strongly arcuate, the sur- 

 face minutely reticulate and distinctly alutaceous, the punctures extremely small, 

 sparse and inconspicuous ; elytral punctures very small, rather feeble ; legs red 

 throughout 67 



67 — Abdominal lines only partially interrupted externally, approaching very close to 

 the hind margin of the segment, as apparently in the two following also ; male 

 with the fifth ventral segment broadly sinuato-truncate, feebly impressed and very 

 inconspicuously pubescent along the sinuous portion. Length 1.7 mm.; width 

 1. 15 mm. Nevada (Reno) inilOCUUS, sp. nov. 



Abdominal lines distinctly interrupted externally, as usual in the present group. . .68 



68— Male with the fifth ventral segment very feebly sinuate at apex but conspicuously 

 clothed with coarse, dense, erect and subflavous pubescence. Length 1.9-2. 1 

 mm.; width 1. 3-1. 55 mm. Indiana — Cab. Levette rusticus, sp. nov. 



Male with the fifth ventral short and broadly truncate but scarcely at all sinuate, the 

 edge with a short and steep bevel and clothed with fine inconspicuous pubescence. 

 Length 1. 8-2.0 mm.; width 1.25-1.5 mm. California (Sonoma Co.). 



aluticollis, sp. nov. 



69 — Elytral punctures rather coarse and sparse though only moderately deep. ... 70 



Elytral punctures fine and close-set ; body smaller and more narrowly oval uniform 

 piceous-black above or paler, with the pronotum still paler toward the apical 

 angles ; prothorax relatively small, moderately transverse, much narrower than 

 the elytra, the sides moderately convergent and feebly arcuate, the punctuation 

 close but very fine ; elytra longer than wide, not very obtuse at tip, feebly black- 

 ish toward the suture and side-margin in some of the paler forms, the pubescence 

 short, abundant and rather coarse. Length 1. 75-1. 9 mm.; width I.O-I.2 mm. 

 California (Monterey to Humboldt Co. ) difficile, sp. nov. 



70 — Upper surface pale rufo-flavate, polished, immaculate, the pubescence rather short, 

 sparse, moderately coarse ; prothorax much narrower than the elytra, minutely, 

 not very closely punctate, the sides only moderately convergent and more or less 

 feebly arcuate; elytra about as long as wide. Length 1.7-2.5 mm.; width 

 I. O-I.75 mm. British Columbia to northern California phelpsi Cr. 



Upper surface pale luteo-flavate, the elytra with small irregular blotches or dashes of 

 black, the pronotum frequently blackish except at the sides, strongly transverse ; 

 elytral punctures binary, as in phelpsi, the larger sometimes tending to linear ar- 

 rangement toward the suture and base ; post-mesocoxal line generally entire but 

 sometimes more or less abbreviated, in one specimen only extending two-thirds the 

 distance to the episternal suture. Length 1.8-2.25 mm.; width I.i5-i.6mm. 

 California (Humboldt to Los Angeles) nebulosus Lee. 



71 — Elytra black, each with a single sharply defined rounded discal pale spot. . . .72
