NORTH AMERICAN COLEOITKRA. 171 



Rufopiceous, scales ot'lireous, rather deiiso, mottled or imieoloroiis, protlionicif 

 punctures deep, not confluent griseiis. 



Dark piceous, tliinlj' clotlied with small grayish scales, prothoracic i)unctures 

 superficial, subconfluent rUMticiiS. 



S. gri»«eus Lee. — Elongate-oval, convex, rufopiceous. scales moderately 

 large, pale ochreous, more dense on the underside than above, those on the pro- 

 thorax narrower, more elongate and directed transversely; elytra variegated 

 with smaller pale brown scales. Beak feebly tapering, as long as head and pro- 

 thorax in the male, longer in the female, thinly clothed with piliform scales from 

 base to middle, nearly glabrous Ijeyond in the male, almost entirely glabrous in 

 the female; ba.sal tufts quite distinct; scrobes, when viewed laterally, visible in 

 almost their whole extent. Antennse slender, inserted a trifle before the middle 

 {%), or a little more than one-third from tlie base ( 9 ) : basal joint stout, second 

 joint elongate, conspicuously longer than the third. Head finely punctate, 

 thinly squaniose. Prothorax scarcely wider than long, a little narrowed in front, 

 broadly rounded on the sides, not evidently constricted in frotit. punctures mod- 

 erately large, impressed, distinct, interspaces shining and scarcely concealed by 

 the scales. Scutel distinct. Elytra nearly two-fifths and suddenly wider at the 

 base than the prothorax, oblong, a little more than one-half longer than wide, 

 humeri prominent, distinctly striato-punctate, not concealed by the scales, third 

 interspace wider at the base, with a short line of pale scales, setae suberect, fine. 

 Prosternum broadly emarginate, postocular lobes not very prominent. Legs 

 long and slender, thighs feebly clavate, tibite very slender; claws connate for 

 fully one-third their length. Length 2.5 — 3. 75 mm.; 0.10 — 0.15 inch. Plate viii, 

 fig. 2[ia. 



Hah. — Nebraska, Dakota. 



Two males and one female specimen in Mr. Ulke's collection. 

 Differing very nuich in size, but not otherwise ; the female specimen, 

 while undoubtedly belonging here, has the scales entirely unicolor- 

 ous and about of equal size, another instance of the unreliability of 

 distinguishing species by coloration. Although the second joint of 

 the funicle i.s distinctly longer than the third, and the claws not con- 

 nate beyond the middle, 1 do not entertain any doubt of this being 

 the species described by LeConte'as griseus. Bears a deceptive ap- 

 pearance to De-wwris incertiis, but the posterior tibiie are distinctly 

 unguiculate, the beak straight and the eyes narrowly sej)arated 

 beneath. 



S. rusticiis n. sp. — Elongate-oval, moderately convex, dark piceous, legs 

 rufous, not very deusely clothed '.yith small, oval, grayish scales. Beak straight, 

 rather stout ( % ), scarcely tapering, not as long as head and prothorax, punc- 

 tured and scaly in its basal half, shining beyond, basal tufts not very evident. 

 Antennje inserted two-fifths from the apex, second joint of funicle one-half 

 longer than the third. Head subglabrous. Prothorax wider than long, nar- 

 rowed anteriorly, not constricted at the apex, sides broadly, but somewhat ir- 

 regularly rounded, convergent beliiiid, confusedly and irregularly punctured,
