above, especially at the base of the third interval, uneven in distri- 

 bution near the suture, very dense and white throughout beneath ; 

 upper surface with the usual stout recurved sette not especially 

 prominent. Beak in the female rather long, punctate, decidedly 

 squamulose except beyond the antennas, very feebly, evenly arcuate 

 and about three-fifths as long as the elytra ; antennae inserted at the 

 middle, rather short, the second funicular joint but very slightly 

 longer than the third. Prothorax small, as long as wide, the sides 

 rounded, feebly convergent and quite distinctly constricted ante- 

 riorly, densely and confusedly squamose and setose. Elytra at base 

 nearly one-half wider than the prothorax, about three times as long, 

 one-half longer than wide ; sides parallel and straight to the middle, 

 then gradually narrowly parabolic ; striae fine, with large elongate 

 punctures toward the sides ; vestiture generally more denuded 

 toward the middle. Length 1.15-2.5 mm.; width O.T-1.0 mm. 



California (Mariposa) — Cab. LeConte ; Arizona and Texas. A 

 small species, distinguishable by its small elongate prothorax and 

 rather long beak, which is punctured and more or less squamulose 

 almost throughout, even in the female. In the male it is short, very 

 densely squamose and hispid, as long as the head and prothorax and 

 with the antennae inserted near apical third. It was taken in great 

 abundance by Mr. Dunn at Benson, Arizona. 



The Texan form identified by LeConte as cornicidatus, belongs 

 to this species. 



23 S. fidlicialis n. sp. — Oblong-oval, convex, rather shining when de- 

 nuded, black, the legs rufous, blackish at base ; elytra broadly pale and rufes- 

 cent toward the sides ; vestiture of the pronotum dense and squamiform at the 

 sides, becoming sparser and fine toward the middle, that of the elytra dense 

 and nearly uniform, consisting of elongate-oval, pointed, yellowish scales, 

 more condensed and coarser in wavy subtransverse areas ; on the under sur- 

 face yellowish-white, the scales smaller and more rounded, dense. Head finely 

 squamulose, the constriction deep, the two corniculate tufts long and conspicu- 

 ous ; beak in the male moderately tliick, even throughout, not tapering, dull, 

 punctate, deeply furrowed and feebly arcuate toward apex, a little longer 

 than the head and prothorax, nearly one-half as long as the elytra ; antennae 

 inserted at apical third, the second funicular joint but slightly longer than 

 the third. Prothorax very nearly as long as wide, the sides broadly, evenly, 

 not very strongly arcuate, moderately convergent, broadly and feebly sinuate 

 toward apex ; disk convex, rather coarsely, deeply, evenly and densely punc- 

 tate, the punctures rounded and all distinct. Elytra at base scarcely two- 

 fifths wider than the prothorax, two and one-half times as long, more than 

 one-half longer than wide, evenly elongate-ogival throughout, the sides not
