CERAMBYCID/E 229 



vestiture above cinereous, coarse, moderate in length on the elytra, 

 more yellowish, long and silky, though not dense, and subdecumbent 

 on the head and pronotum; head nearly as wide as the prothorax, 

 with notably prominent eyes, the antennae thick, nearly as in the 

 preceding; prothorax nearly a fourth wider than long, rather strongly 

 narrowed and deeply constricted at apex, unusually finely, rather 

 sparsely punctured, the impunctate line in about basal half broad; 

 scutellum densely yellowish-pubescent; elytra with rather small but 

 deep, somewhat close-set punctures, becoming fine and closer api- 

 cally. Length (cf ) 6.6-7.5 mm.; width 2.2-2.8 mm. California, 

 Levette lepidula n. sp. 



19 Form oblong-parallel, moderately convex and shining, black, the 

 elytra somewhat piceous-black, generally faintly dark blue basally 

 but sometimes pallescent and occasionally red-brown with a broad 

 entire indefinite sutural vitta and another marginal and not at- 

 taining the base, the two uniting at the apex, the abdomen black to 

 ferruginous, apparently in both sexes; pubescence coarse, yellowish, 

 dense, darker, erect and less conspicuous anteriorly; head finely, very 

 densely punctate, the eyes moderately prominent; antennae moder- 

 ately short and thick, a little more slender and ferruginous (c? 1 ), the 

 third joint somewhat more than twice as long as wide; prothorax 

 not quite as long as wide to distinctly transverse, only slightly 

 narrowed but rather strongly constricted at apex, finely but deeply, 

 sparsely punctate; elytra very rapidly and obtusely rounded at tip, 

 the parallel sides broadly sinuate behind the humeri, twice as wide 

 as the prothorax and between three and four times as long, rather 

 coarsely and closely, very deeply punctate, more finely but distinctly 

 behind, the surface generally with two partial and less punctate 

 lines traceable; abdomen moderately punctulate, with unusually 

 short and sparse pubescence; male with the fifth ventral no longer 

 than the fourth, very broadly arcuate; female with this segment a 

 little longer than the fourth and very evidently more narrowly 

 rounded; body rather shorter in the former. Length (c? 1 9 ) 7.0-9.6 

 mm.; width 2.3-3.8 mm. California (Mokelumne Hill, Calaveras 

 Co.), Blaisdell versicolor n. sp. 



Form very stout, the hind body somewhat as in bivittata, fusco-testaceous, 

 pallidly pubescent; prothorax shorter than wide, the sides parallel 

 posteriorly, rounded anteriorly, the apex narrowed and constricted, 

 densely punctate, with a median smooth space, especially posteriorly; 

 elytra broad, convex, sparsely punctate, more finely behind, toward 

 base irregular, having indistinct smooth lines, giving the appearance 

 of faint longitudinal stripes, of which the inner runs obliquely forward 

 toward the humerus, so as to tend to unite with the others; an- 

 tennae and legs dark piceous, the former rather stout, with the third 

 and fourth joints equal. Length 9.0 mm. California., .pinguis Lee. 



There can be but little doubt, so far as now apparent, of the 

 distinctness of most of the forms above defined, though, on the 

 whole, there is marked monotony; some, such as sub&nea, seem to
