260 CURCULIOXIDJE. 



[LeConte. 



Prothorax about as long as wide; elytral white spot 

 conspicuous ; 



Elytra but little wider than prothorax 1. californicus. 



Elytra much wider than prothorax 2. oculatus. 



Prothorax conspicuously wider than long. Elytra 

 much wider than prothorax 3. subfasciatus. 



1 . P. californicus, n. sp. 



Elongate-oval, black, above irregularly clothed with narrow fulvous 

 scales, mixed at the sides of the prothorax with white; scutellum black; 

 elytra with a common sutural spot behind the middle, extending to the 

 second stria, and a few scattered dots white. Beak rather stout, finely 

 punctured, feebly carinate near the base; front very narrow; eyes bordered 

 behind with pale scales. Prothorax not wider than long, gradually nar- 

 rowed from base to tip, sides straight; disc coarsely densely punctured, dis- 

 tinctly carinate. Elytra very little wider than the prothorax, elongate, 

 humeri oblique, stria? well impressed, interspaces flat, finely punctured. 

 Beneath clothed with dirty gray scales; thighs distinctly toothed, hind pair 

 with a black ring; tibiae with a small terminal hook; ungues very small. 

 Length 3 mm. ; .12 inch. 



Calaveras, California; Mr. Crotch. More elongate than the other two 

 species, and resembling in form Copturus operculatus, though smaller. 



2. P. oculatus. CryptorliyncJius ocul. Say, Journ. Ac. Nat. Sc. iii, 

 308; ed. lee. ii, 172; Copturus nanus\ Dej. Cat. 



Southern and Western States. The sutural white spot is small and ex- 

 tends only to the first stria. The upper surface is thinly clothed with ful- 

 vous hair-like scales, and only slightly mottled. The prothorax is nearly 

 as long as wide, slightly rounded on the sides. The elytra are suddenly 

 one-third wider than the prothorax and narrowed behind. Length 3 mm. ; 

 .12 inch. 



3. P. subfasciatus, n. sp. 



Rather stout in form, black, thinly and irregularly clothed with fine white 

 hair-like scales, forming transverse bands on the elytra; the white spot is 

 therefore not very conspicuous. Beak brown, outer half nearly smooth, 

 base punctured and striate; antennas testaceous, front very narrow. Pro- 

 thorax about twice as wide as long, narrowed gradually from the base, 

 sides feebly rounded behind, and very slightly sinuate near the tip; very 

 coarsely and densely punctured, not carinate; the white scales are thinly 

 placed, and form three broad vittae. Elytra near the base about one-third 

 wider than the prothorax, humeri more rounded and less prominent than 

 in P. oculatus; narrowed behind, stria? wide, deep, punctured, interspaces 

 narrow, with lines of white pubescence, so interrupted as to produce three 

 transverse bands; one basal, surrounding a humeral dark spot, one behind 

 the middle, and one near the tip; these bands are also connected along the 

 suture, and at other places. Beneath thinly clothed with gray scales,
