others by the straight and nearly smooth beak. The ventral sutures arc 

 slightly yet distinctly curved. The form of body and the color of the 

 scales gives a resemblance to Sihynes, from which it is abundantly distin- 

 guished by the simple claws. 



11. S. sordidus, n. sp. 



Black, elongate, densely clothed with rather small dirty gray scales. 

 Beak as long as the head and prothorax, nearly straight, punctured, tip 

 smooth and shining. Prothorax longer than wide, narrower in front, 

 slightly rounded on the sides, postocular lobes wanting. Elytra oblong, 

 humeri rounded, prominent, striae fine, interspaces flat. Antennae with 

 the funicle rather slender, second joint longer than third. Claws rather 

 large, approximate, not connate. Length 2 mm.; .08 inch. 



Texas. Exactly resembles in appearance 8. griseus, but diflers by the 

 larger claws, and more slender antennae. 



12. S. cinereus Motsch., Bull. Mosc, 1845, ii, 376. 



California and Vancouver Island; G. R. Crotch ; Dr. Thevenet. Easily 

 known by its larger size (2.5 mm.; .10 inch), prothorax with rounded 

 sides, and mottled color; a few short hairs are mingled with the scales, 

 which are broad oval. The prothorax is thickly punctured, and distinctly 

 constricted near the tip. The elytra are comparatively longer and less 

 convex than in the neighboring species, thus producing a resemblance to 

 Dorytomus. 



13. S. squamulatus, n. sp. 



Black, densely clothed with i-ather large oval gray scales, mottled with 

 brown upon the elytra. Beak brown, longer than head and prothorax, • 

 slender, nearly straight, shining at tip, punctui-ed and pubescent at the 

 base. Prothorax as long as wide, rounded on the sides, narrower in front, 

 postocular lobes not distinct. Elytra oblong, one-third wider than the 

 prothorax, humeri rounded, prominent, striae fine. Antennae brown, with 

 second joint of funicle scarcely longer than third. Legs brown, claws 

 small, connate for about one-half their length. Length 2 mm.; .075 inch. 



Two specimens, Detroit, Michigan ; Messrs. Hubbard and Schwarz. 

 An inconspicuous species, which may be easily recognized by the fore- 

 going characters. 



14. S. corniculatus. TycMus corn., Fahraeus, Sch. Cure, vii., 2d, 309. 

 Middle and Western States. A very small species, easily known by the 



narrow scales and rounded sides of the prothorax. Length 1.6 mm.; 

 .065 inch. 



Dark brown, not very densely clothed with narrow, small, whitish and 

 yellowish scales. Beak as usual. Prothorax as long as wide, narrowed in 

 front, mach rounded on the sides, convex, densely and coarsely punctured. 

 Elytra suddenly one-half wider than the prothorax, elongate, not rounded 

 on the sides, striae deep, punctured, interspaces flat. Antennae and legs 

 paler brown. Claws very small, partly connate.
