XOKI'H AMERICAN COLEOPTKRA. 141 



of fiinicle very robust, sc(H)iu1 not elongate, as long as the tliird, outer joints 

 wider, merging into the club, latter ratiier thinly pul>escent, basal joint glab- 

 rous. Head densely punctured. Prothorax wider than long, strongly narrowed 

 anteriorly, broadly and feebly constricted at the apex, strongly rounded on the 

 sides, not closely punctured, punctures large, somewhat transversely oval, in- 

 terspaces shining, a smooth median line confined to the disc. Scutel relatively 

 large, not scaly. Elytra ovate, less than one-third vvider at the base than the 

 prothorax, nearly twice as long as wide, sides feebly rounded ; humeri prominent, 

 glabrous; coarsely striate, punctures approximate, moderately large; ir.terspaces 

 feebly convex, rugulose, puuctulate, shining between the scales, setae obsolete. 

 Prosternum very short in front of coxse, transversely impressed, postocular lobes 

 obsolete. Legs stout, thighs clavale, tibia? widened to the apex, terminal hooks 

 distinct, tarsi not very slender, third joint broadly and deeply bilobed, fourth 

 projecting less than the length of third; claws connate for about two-thirds 

 their length. Length 1.9 mm. ; 0.08 inch. 



Hid). — Texas. One % specimen in Mr. Ulke's collection. 



A very isolated form. The above specimen is abraded ; it may 

 readily be recognized by its very small size, shining surface, bright 

 rufous legs, absence of postocular lobes and densely punctured head. 

 This may prove to be perpiisillus Casey, the second joint of the 

 funicle, however, is not longer than the third. 



S. pilNilliis n. sp. — Elongate-oblong, black, legs rufo-piceous, not very 

 densely clothed with elongate-oval, pale ochreous or gray scales. Beak robust, 

 cylindrical, not at all tapering, shorter than head and prothorax { %) ; densely 

 punctured throughout, except at the apex, striolate, densely scaly from base to 

 the insertion of the antennae, basal tufts small, incision superficial; scrobes 

 scarcely oblique; a little longer, more slender and opaque in the female. An- 

 tennae not very slender, first joint of funicle stout, second not elongate, one-half 

 longer than the third, outer joints widened, club rather large, not densely pu- 

 bescent, basal joint subglabrous. Head opaque, rugulose, with a few scattered 

 punctures and scales. Prothorax scarcely wider than long, feebly narrowed in 

 front, scarcely constricted at the apex, broadly rounded on thesides, very slightly 

 narrowed toward the base; surface, where denuded of scales, opaciue, densely 

 punctato-granulate, granules very fine. Scutel very small, glabrous. Elytra 

 scarcely more than one-fourth wider at the base than the prothorax, elongate- 

 ovate, humeri prominent, sides nearly straight and parallel for one-half, then 

 gradually rounded to the apex ; striae fine, feebly impressed, remotely i)unctured. 

 interspaces, when denuded, transversely rugose; interstitial setae very small, 

 white, hair-like. Prosternum as in the preceding species, postocular lobes feeble. 

 Thighs rather strongly clavate ; tibite widened at tip, anterior emargiuate inter- 

 nally above the apex; terminal hooks quite prominent; tarsi piceous, third 

 joint broadly bilobed, fourth projecting the length of the preceding joint; claws 

 connate two-thirds their length. Length 2.0 mm.; 0.08 inch. 



Hub. — California (St. Bernardino), Arizona (?). 



Two males and one female. Dr. Horn's and my own collection. 

 The Arizona specimen differs somewhat from the others, which have 

 served as the types for the above description, by the legs being pi-
