line on the third interspace, surface not or very indistinctly mottled with sliglitly 

 darker scales. Thighs not strongly clavate, tibife slender, especially the anterior, 

 widened and all distinctly hooked at the tip ; claws connate nearly to the middle. 

 Length 2.75—3.0 ram.; 0.11—0.12 inch. 



Hab. — California, Arizona. 



Seven male and two female specimens, Dr. Horn's and Mr. Ulke's 

 collection. A male s{)ecimen from Arizona in Mr. Ulke's collection 

 has the thorax a little more strongly rounded and the auteiinse in- 

 serted two-fifths from the apex. From fallax, which it resembles in 

 size and form, it is distinguished by its differently colored scales and 

 the articulating surfaces of the posterior tibiae not freely open and 

 ascending externally. From obtectus, to which Casey referred a 

 specimen of this species sent him for determination, it is easily dis- 

 tinguished by the elongate second joint of the funicle, the elytra 

 distinctly wider at base than the prothorax and its nearly uniform, 

 pale ochreous vestiture. 



S« COPiiiculatus Fab.— Oblong-oval, moderately convex, black, legs red- 

 dish, scaly vestiture dense, consisting of oval or suborbicular, grayish brown 

 scales, paler on the underside. Beak curved in the male, moderately robust, 

 cylindrical, scarcely tapering, punctured and scaly in its proximate half and 

 about as long as head and prothorax in the female, quite slender, somewhat 

 tun:escent, scaly aud punctured near the base, shining beyond, basal tufts quite 

 distinct. Antennae inserted two -fifths from the apex ( % ), or a trifle behind the 

 middle ( 9 )i first joint of funicle rather large, second about one-half longer than 

 the third, front punctured and scaly. Prothorax a little wider than long, nar- 

 rowed in front, not distinctly constricted at the apex, somewhat narrowed be- 

 hind, rounded on the sides, sui'face coarsely aud subconiuently punctured, 

 punctures concealed by the scales, latter intermixed with small, suberect, scale- 

 like hairs. Scutel very small. Elytra two-fifths wider at the base than the pro- 

 thorax, and about one half longer than wide, humeri prominent, sides straight for 

 one-half their length, strife fine, remotely punctured, nearly concealed by the 

 scales, interspaces nearly flat, finely rugose, somewhat shining (where denuded), 

 interstitial sette not evident. Thighs feebly clavate, tibise slender, somewhat 

 widened and distinctly hooked at the apex in all, claws connate one-third their 

 length. Length 2.0—3.0 mm.; 0.08—0.12 inch. Tlate viii, fig. 23. 



Hab. — Eastern States. 



Numerous specimens of this species are before me. Dr. LeConte's 

 description does not apply to the species under consideration, but 

 rather to pauxillus ; the prothorax is not strongly rounded on the 

 sides and the scales not narrow, white or yellow. 



The material before me, while agreeing in all essential characters, 

 presents some notable variations worthy of special mention, as fol- 

 lows :
