ERIRHININI. 187 



rounded, separately sub-acuminate ; striae punctured, interspaces slightly 

 convex, each with a row of rather long reclinate bristles ; posterior callus 

 not prominent. Antennae and legs dark ; tarsi short. Length 3.2 mm. ; 

 .125 inch. 



One specimen, Point Huron, Mich. ; Hubbard and Schwarz. 



The markings of the elytra are not very distinct ; the most conspicuous 

 is a pale stripe extending on the fifth and sixth interspaces from the oblique 

 impression to behind the middle, where it is flexed rectangularly and runs 

 to the suture. 



9. B. californicus. n. sp. 



Rather robust, black, clothed with dark-gray scales of uniform color. Beak 

 stout, curved, shorter than the prothorax, scaly ; frontal fovea not deep. 

 Prothorax wider than long, coarsely granulated and rugose ; sides straight, 

 diverging slightly from the base for two-thirds the length, then rounded 

 and narrowed to the tip, where it is strongly constricted ; with a broad 

 dorsal channel near the base. Elytra nearly one-half wider than the pro- 

 thorax, humeri oblique, slightly rounded ; sides parallel, then obliquely 

 narrowed, and narrowly rounded at the tip ; disc flattened from the 

 suture to the third stria, and from the base for three-fifths the length, striae 

 fine, interspaces slightly convex ; posterior callus prominent ; there is a 

 feeble tubercle on the third interspace at about two^hirds the length. 

 Antennae and legs reddish-brown ; tarsi long. Length 2.8 mm. ; .11 inch. 



One specimen, San Diego, Cal. ; Gr. R. Crotch. 



Differs from B. restrictus by the tubercle on the third interspace behind 

 the middle, and by the absence of the white spot which occupies a similar 

 position in that species. 



10. B. restrictus, n. sp. 



Black, covered with dirt-colored scales, beak subcarinate, nearly as long 

 as the prothorax ; the latter as wide as long, slightly w r ider from the base 

 forwards, with the sides straight, for three-fourths the length, then rounded 

 and suddenly constricted, more strongly than in the other species; coarsely 

 granulate. Elytra with the humeri oblique, obtusely angulated, less promi- 

 nent, striae deep, interspaces convex, fifth terminating in a small conical 

 tubercle, covered with white scales ; there is also a small transverse white 

 spot on the second and third interspaces at about two-thirds the length. 

 Antennae tibiae and tarsi brown, third joint not dilated, fourth longer than 

 the two preceding united. Length 2.5 mm.; .10 inch. 



One specimen; Texas; Belfrage. The tarsi are more slender than in the 

 neighboring species. 



11. B. pusillus, n, sp. 



Less robust, black, clothed with dirt-colored scales, elytra with a broad 

 toothed transverse band behind the middle. Beak stout, curved, as long 

 as the prothorax, scaly, frontal fovea faint. Prothorax about as wide as 

 long, sides straight, suddenly rounded, narrowed and strongly constricted 

 near the tip; coarsely granulated. Elytra nearly one-half wider than the
