North American Rhynchophora. 293 



small, dense, rounded, finely and not very distinctly strigose on the 

 elytra, longer and more deeply strigose on the pronotum, which is feebly 

 trivittate. Head distinctly wider than long; front and base of beak 

 flat, rather finely, very densely and deeply punctate; scales distinct in 

 two spots in the middle near the base, and in an arcuate line on each 

 side from the base along the eye and across the base of the beak, else- 

 where devoid of scales, except a few sparse cupreous ones scattered over 

 the apical impression of the beak; surface bristling with erect setae 

 which are rather dense and uniform in color; median sulcus deep, but 

 narrow; eyes large, inner margin very distinctly elevated; beak scarcely 

 as long as the head, wider than long, apical impression short, slightly 

 declivous and feeble, carinse feeble and short, impression not at all dis- 

 tinctly limited behind; antennae rather slender; basal joint of funicleas 

 long as the next two together, two to four distinctly elongate, second 

 slightly the longer. Prothorax cylindrical, slightly wider than long, 

 distinctly constricted at apical sixth, and more finely so just before the 

 basal margin; intervening sides broadly and distinctly arcuate; apex 

 and base equal, the former subtruncate, the latter very feebly arcuate; 

 disk finely, densely punctate, rather densely squamose; setae long, fine 

 and abundant. Elytra about four-fifths longer than wide, not one-half 

 wider than the prothorax; sides in basal two-thirds straight and parallel, 

 thence rather acutely rounded behind, the sides before the apex very 

 broadly and feebly sinuate; each elytron with a very miimte feeble sub- 

 apical umbo; disk convex, finely, feebly striate; striae with very fine, 

 but rather distinct approximate punctures ; intervals subequal, nearly 

 flat, dark setae rather dense, fine, attenuate; pale setae sparse, and but 

 slightly longer. Length 5.3 mm. 



California (Monterey, Monterey Co. 1). 



The fine setigerous appendage of the ungues is distinct and 

 sometimes gives the appearance of a finely cleft claw. This type 

 specimen, although a female because of the unimpressed abdo- 

 men, is apparently distinct in its punctuation and yestiture. 



S. explicitus n. sp. — Elongate, convex; scales moderate in size, 

 rounded, very dense and overlapping on the elytra, more sparse on the 

 pronotum where they do not obscure the punctures, equal in size on the 

 elytra and pronotum, piceous in color, finely and closely strigose; pro- 

 notum not at all vittate except at the base, where there are three small 

 paler spots; abdomen very densely setose and squamose, scales dark 

 gray, distinctly plumose toward apex. Head slightly transverse, about 

 equal in length to the beak; the latter slightly wider than long; front 

 and basal half of beak nearly flat, coarsely, very densely, and deeply 

 punctate, only squamose near the eyes, and with a few small cupreous 

 scales at the apex of the beak; surface covered with a confused mass of 

 setae, r'ather fine, some cinereous and others subcupreous; median
