rather suddenly narrowed in front, not broiully Imt distinctly constricted at the 

 apex, sides straight and nearly parallel behind the middle; surface evenly and 

 not densely punctured, punctures rather small, a faint njedian basal vitta of paler 

 scales; scutel distinct, scaly. Elytra scarcely one-third wider at the base than 

 the prothorax, sides parallel for three-fifths their length, thence gradually nar- 

 rowed to the apex, strife rather fine, distinctly and remotely punctured, inter- 

 spaces flat, setffi distinct ; indistinctly mottled with pale brown or whitish scales, 

 the latter more conspicuous on the humeri and a short basal line on the third 

 interspace. Presternum rather deeply en^arginate. Thighs I'ather strongly cla- 

 vate, tibia? not very slender, nearly parallel, strongly hooked at the apex, setu- 

 lose within ; tarsi rather stout, fourth joint projecting beyond the third about 

 the length of the latter; claws connate beyond the middle. Length 3.5 — 4.5 

 mm.; 0.15—0.20 inch. Plate vii, figs. 3, '.in, 9, da and <)/;.

The above description does not tally in all ])ai-liculars with that 

 given by Casey ; the second funicular joint is about one-half longer 

 tlian the third, the elytra at most one-third wider at base than the 

 prothora.\ and the claws distinctly connate beyond the middle. 



S. Jiilriealiis Casey.— Oblong, piceous, very densely scaly, scales large, 

 broadly oval, y<!llovvish brown or gray on the legs and underside of the body, 

 intermixed with numerous, erect, squamiform, white sotse, dark gray, intermixed 

 witli blackish and yellowish brown above. Beak robust, curved, longer than 

 head and prothorax, coarsely and densely punctured, especiailly in the male, 

 striate; densely scaly from the base to the insertion of the antennse, scales in- 

 termixed with stout, suberect bristles, somewhat flattened above, especially 

 toward the base, basal tufts prominent, constriction very deep; scrobes scarcely 

 oblique. Antennae not slender, inserted a little before the middle ( 9 ). o'" less 

 than two-fifths from the apex ( % ), first joint of funicle rather stout, second not 

 elongate, scarcely longer than the third, outer joints transverse. Head finely 

 rugulose, front puuctulate, scaly. Prothorax distinctly wider than long, rather 

 suddenly narrowed in front and deeply constricted behind the anterior mui-giu, 

 sides behind the anterior third straight, parallel, or very feebly rounded, punc- 

 tures small, not dense, concealed by the scaly vestiture, latter intermixed with 

 coarse, suberect, dark brown setae, a line on the lateral margin and an indistinct 

 median vitta of white scales; scutel scaly. Elytra two-fifths wider at base than 

 the prothorax, sides nearly straight for three-fifths their length, then gradually 

 rounded to the apex ; strite well impressed, distinctly punctured, punctures con- 

 cealed by the scales; interstitial setae brownish, conspicuous ; intersj)aces slightly 

 convex, surface mottled, humeri paler; j)rosternum broadly eniarginate, trans- 

 versely impressed, postocular lobes prominent: femora clavate. tibiai nn.derately 

 stout, terminal hooks distinct; tarsi not stout, third joint not bi'oadly bilobed. 

 but little wider than the preceding joint, fourth long and slender, projecting 

 more than the length of the third ; claws connate for one-half their length. 

 Length 3.0-3.2 mm. ; 0.12—0.13 inch. 



Hab. — Texas, Arizona. 



Two males and one female in my collection. Casey's descrijition
