sometimes mottled ; it is easily recognized by the ovate elytra, which are 

 distinctly wider at the middle than at^the base. 



3. S. griseus, n. sp. 



Black, not very densely clothed with oval gray scales; beak longer than 

 head and prothorax, less curved than usual; squaiuose towards the base. 

 Prothorax without postocular lobes, slightly longer than wide, gradually 

 narrowed from the base, feebly rounded on the sides, moderately constric- 

 ted at the sides near the tip ; not very convex, finely punctured. Elytra 

 elongate, one-third wider than the prothorax, humeri not very prominent,

 Antennae and legs very dark -brown. Length 2 mm.; .08 inch. 



Southern and Western States, Georgia to Kansas. This is probably 

 Micronyx cinereus jDej., a name since used for another species. 



4. S. obtectus, n. sp. 



Black, very densely clothed with broadly oval yellowish scales, conceal- 

 ing the punctures; beak as long as the head and prothorax, curved ; pro- 

 thorax a little longer than wide, gradually narrowed in front, and con- 

 stricted as in griseus, but more rounded on the sides, strongly, not densely 

 punctured. Elytra of the same form as in griseus, stria3 concealed by the 

 scales, but when they are removed, deep and punctured, interspaces flat, 

 nearly smooth* Legs and antennae very dark -brown. Length 2 mm.; .08 

 inch. 



California, found by me at San Diego.

Piceous, clothed with small ochreous scales ; beak slightly curved, as 

 long as the head and prothorax, punctured, opaque, thinly pubescent. 

 Prothorax a little w T ider than long, rounded on the sides, narrower in 

 front, convex, densely punctured, postocular lobes broad, distinct. Elytra 

 oblong, convex, sides parallel, then rounded at the tip ; one-third wider 

 than the prothorax, humeri prominent, rounded; striae well impressed, in-

Texas. Belfrage ; one specimen. 



6. S. pusio^n. sp. 



Quite similar to 8. obtectus, but very much smaller, with the scales 

 broadly oval and very dense. The striae of the elytra seem to be liner and 

 somewhat nearer by pairs, the second and fourth interspacas appearing 

 wider. Antennae and legs dark-brown. Length 1.5 mm.; .06 inch.
