S. iiiNtnbiliN Casey.— Oblong-oval, pitchy black, legs reddish, rather densely 

 clothed with elongate oval scales, those on the upjier surface yellowish brown 

 with a large sutural spot on tha elytra white, before which there is a darker' 

 almost blackish space; underside yellowish, or grayish white. Beak robust, 

 nearly straight, scarcely as long as head and prothorarc, opaque, excejtt at the 

 apex, punctured and striate, densely scaly in its basiil half, tufts prominent; 

 scrobes oblique. Antennte stout, inserted two-fifths from the ajjcx. second .joint 

 of fiinicle a little longer than the third, outer joints widened. Head finely 

 alutaceous, front not densely scaly, with a few remote punctures. Prothorax a 

 little wider than long, rather strongly narrowed in front, broadly constricted at 

 the apex, rounded on the sides, the latter convergent posteriorly, surface densely 

 but not coarsely punctured, a narrow median line, lateral margin and a sinuous 

 line on eacli side of the disc and connected by another less distinct, curved, 

 transverse line, whitish. Scutel very small, punctiforra. Elytra one-third wider 

 at the base than the prothorax, sides sti'aight, parallel for one-half their length, 

 then gradually rounded to the apex, distinctly striato-punctate ; interstitial seta 

 procumbent, scarcely visible, the large, blackish quadrate space extends from 

 near the base to beyond the middle and is interrupted at the latter by the large, 

 transverse, common sutural spot of large wliite scales. Prosternum broadly 

 eraarginate, postocular lobes distinct. Thighs strongly clavate, tibiae rather 

 short, not slender, subparallel, slightly widened at the apex, terminal hooks 

 small, though distinct; tarsi moderate, third joint feebly bilohed, fourth pro- 

 jecting a little more than the length of the preceding joint; (daws connate for 

 one-half their length. Length 2.2—2.5 mm. ; 0.09—0.10 inch.

Eight specimens, all males, are before me. Very closely resem- 

 bles quadrifer Casey, but the beak is stouter, nearly straight, the 

 prothorax quite evidently wider than long, rather strongly rounded 

 on the sides, the dark elytral space less sharply defined with the 

 large, white sutural spot very conspicuous and the thighs strongly 

 clavate. The black scales are more easily abraded while the larger 

 scales of the white spot are persistent and generally present even in 

 otherwise badly denuded specimens. Resembles, also somewhat, 

 spretus, but the arrangement of the scales is different. Determined 

 for me by Casey as his imtdhUis, the author having a badlv abraded 

 specimen for his type. The scales are predominantly yellowish 

 iirown, not white. 



S. iiiibiliis u. sp.— Oblong-oval, black ; legs piceous, rather densely clothed 

 with moderately large, oval yellowish and grayish white scales, nubilated above 

 with areas of darker scales. Beak robust (female), scarcely as long as head and 

 prothorax, cylindrical, rather closely punctured from base to beyond the middle, 

 then more remotely punctured, shining, densely scaly from base to the itisertion 

 of the autennte, basal tufts prominent, incision deep; scrobes scarcely oblique; 

 antennje robust, first joint of funicle stout, not elongate, second joint of funicle 

 scarcely longer than the third, outer joints scarcely wider, clava densely pubes- 

 cent, basal joint glabrous. Head finely rugulose, front densely scaly, jjunctured.
