Coleopterological Notices, IV. 389 



whitish toward the sides and along the middle of the pronotum and broadly 

 in the middle of the elytra, brown elsewhere, yellowish-white and very dense 

 beneath, the elytra with a large sutural quadrate spot from basal sixth to 

 just behind the middle, which is abruptly limited and clothed with piceous- 

 black scales ; recurved setae not very conspicuous. Head squamose, the con- 

 striction deep ; beak in the male thick, feebly arcuate, slightly longer than 

 the head and prothorax, densely opaque, conspicuously squamose and hispid 

 almost throughout, the basal tufts distinct ; antennas inserted near apical 

 third, the second joint of the funicle but slightly longer than the third. Pro- 

 thorax very slightly wider than long, subparallel and broadly, rather feebly 

 arcuate at the sides, distinctly constricted behind the apex. Elytra at base 

 two-fifths wider than the prothorax, not quite three times as long, parallel 

 and nearly straight at the sides in basal half, the striae indicated laterally 

 only by the finest partings of the vestiture, more distinct toward the suture. 

 Tarsal claws rather small, connate in basal third. Length 2.2 mm. ; width 

 1.0 mm. 



Arizona. 



The large subbasal quadrate spot of velvety black will serve to 

 render this species easily recognizable. It somewhat resembles 

 vestitus in outline, but is rather stouter. Two specimens. 



7 S. profusiIS n. sp. — Oblong, convex, black, the legs scarcely piceous ; 

 body densely clothed above with large, broadly oval, piceous scales, widely 

 overlapping, feebly and confusedly intermixed with slightly paler scales on 

 the elytra and narrowly paler along the middle of the pronotum ; scales of 

 the under surface rather paler and not quite so large ; recurved setae of the 

 elytra not conspicuous, more evident anteriorly. Head squamose ; constriction 

 deep ; beak in the male short, rather stout, feebly, evenly arcuate and slightly 

 tapering from base to apex, densely punctate, hispid throughout with stout 

 erect setae, and, in addition, very densely squamose toward base, as long as 

 the head and prothorax, the antennae inserted just visibly beyond the middle, 

 in the female but little longer, more slender, feebly arcuate, smooth, polished, 

 very minutely, sparsely punctulate and glabrous, but rather suddenly swollen, 

 hispid and very densely squamose in a little more than basal fourth, slightly 

 longer than the head and prothorax but not more than two-fifths as long as 

 the elytra, the antennae inserted at basal two-fifths ; antennae rather long, the 

 second funicular joint as long as the next two in the female, shorter in the 

 male. Prothorax nearly one-third wider than long, the sides parallel and 

 straight in basal two-thirds, then rounded convergent and feebly constricted 

 to the apex, the latter not more than one-half as wide as the base ; punctures 

 when denuded rather large, round and well separated. Elytra at base one- 

 half wider than the prothorax, about three times as long, parallel in basal 

 two-thirds, then rapidly, acutely ogival ; striae indicated by narrow partings 

 of the vestiture. Tarsal claws rather small, subparallel, connate toward base. 

 Length 2.4-3.7 mm. ; width 1.15-1.7 mm.
