Coleopterological Notices, IV. 397 



Oblong-oval, black, densely and uniformly clothed with elongate- 

 oval appressed scales, cinereous to ochreous in color, each interval of 

 the elytra with a single series of short robust recurved squamules. 



This species is either one of the most variable of curculionides in 

 structural peculiarities affecting parts of the body referred to by 

 LeConte for generic characters, or the large series before me is 

 made up of closely allied species which can only be differentiated by 

 the collection of abundant material from carefully recorded localities. 

 I will at present simply describe certain modifications noticed in three 

 female types taken in Iowa, New Mexico and northern California 

 respectively : 



1 — Beak fully one-half as long as the body, extremely slender ; 

 basal joint of the funicle barely as long as the next two, the second 

 fully three-fourths as long as the first ; legs, tarsi and antennae pale 

 rufous ; beak rufescent. 



2 — Beak very long, nearly two-thirds as long as the body, thicker ; 

 basal joint. of the funicle fully as long as the next three ; second one- 

 half as long as the first ; legs, antennae and beak throughout black. 



3 — Beak much shorter, stouter, two-fifths as long as the body; 

 basal joint of funicle longer than the next two ; legs rufous, the 

 tarsi darker ; beak and antennae blackish, the club paler. 



In the male the beak is very much shorter and thicker, densely 

 punctate, squamose, with the antennae inserted just, beyond the 

 middle. Length 2.2-4.0 mm. ; width 1.0-1.8 mm. 



Iowa to Arizona, northern California. A very abundant species ; 

 the smallest and largest in my series of thirty or more specimens 

 are both females. 



20 S. griseus Lee— Proc. Am. Phil. Soc, XV, p. 171. 



Narrowly oblong-oval, convex, black, the legs dark rufo-piceous ; 

 scales moderate in size, broadly oval, dark brownish and paler, dense 

 but not overlapping on the upper surface, white and very dense 

 beneath. Beak in the female very slender, cylindrical, just visibly 

 bent, much longer than the head and prothorax and nearly two- 

 thirds as long as the elytra, punctured, opaque and squamulose 

 toward base, smooth and with small subelongate erosions toward 

 apex ; antennae inserted slightly behind the middle, short, the scape 

 not quite attaining the eye ; second funicular joint but slightly 

 longer than the third. Prothorax large, fully as long as wide, sub- 

 parallel and broadly, evenly and strongly arcuate at the sides, rather
