150 WILLIAM G. DIETZ, M.D. 



Protborax a little wider thau loug, very little wider at the base than at tbe apex, 

 sides broadly rounded, apex broadly but feebly constricted, surface rather closely 

 punctured, scales uniformly grayish white, intermixed with rather long, erect 

 setae, an indistinct median and lateral line of condensed scales. Scutel not 

 obvious. Elytra two-fifths wider at the base than the prothorax, ovate, one- 

 half longer than wide, humeri prominent, rounded, sides nearly straight for 

 about one-half their length, then rounded to the apex, strise impressed, with 

 rather approximate punctures, interstices rugose, setse long, squamiform, con- 

 spicuous ; large areas of darker scales along the suture, some smaller patches 

 along the sides; antecoxal ridges distinct; postocular lobes feeble. Thighs feebly 

 clavate. tibiae rather stout, nearly parallel, terminal hooks very small, tarsi stout, 

 third joint not broadly bilobed, fourth projecting the length of the preceding 

 joint; claws very small, connate a little beyond their middle. Length '2.0 mm. ; 

 0.08 inch. 



Hab. — California. 



A female specimen in my collection. Closely related to the next 

 species. There is a large abraded spot on the elytral disc before the 

 middle, but from a few remaining scales it appears that in great part 

 at least it was covered with dark scales. Might also be confounded 

 with instahilis, but is smaller, the scales rather yellowish than brown, 

 absence of the large, white sutural spot and the femora feebly clavate. 



S, posticus n. sp. — Very closely resembles nubilus in general form, colora- 

 tion and arrangement of scales, but differs as follows : beak ( 9 ) less robust, as 

 long as head and prothorax. less densely punctured and scaly, more shining in 

 apical half. Prothorax more than one-half wider than long, more strongly 

 rounded on the sides, coarsely and confluently punctured, punctures arranged in 

 such a way that the intervening ridges form concentric ruga?, sparsely scaly, a 

 feeble, smooth discal line. Scutel distinct, glabrous. Legs rufous; tibial spurs 

 more conspicuous; third tarsal joint broadly bilobed, nearly twice as wide as the 

 second, fourth joint projecting less than the length of the preceding. Length 

 2.5 mm. ; 0.10 inch. Plate vii, fig. 18. 



Hab. — Maryland. 



A female specimen in Mr. Ulke's collection. More robust and a 

 little larger than tiie preceding. There is no difference in the elytral 

 coloration worth mentioning. Resembles in form tychioides Lee, but 

 is smaller, the beak less robust, scarcely tapering and scaly vestiture 

 equally dense above. 



S. seriatus Lee. — Elongate, black, clothed with oval, dirt-colored scales. 

 Beak curved, stout in the male, slightly thicker in the middle, distinctly taper- 

 ing to the apex, densely punctured, finely striate, scaly toward the base : in the 

 female less robust and cylindrical, about as long as bead and prothorax, antenna? 

 inserted two-fifths ( % ) from the apex, or very slightly ( 9 ) before the middle, 

 not slender, first joint of funicle stout, second distinctly longer than the third, 

 outer joints wider. Head opaque, finely alutaceous. Prothorax about as long 

 as wide, scarcely narrowed anteriorly, very feebly constricted at tbe apex, broadly
