own handwriting. The elytra are comparatively long and slightly 

 widened posteriorly. Casey's description does not corresj)ond with 

 the above, his statement " Elytra one-half to three-fifths longer than 

 wide," is hardly correct, the prothorax is evidently wider than long, 

 and the punctures are not close set. 



S, !«<*:tl3itor n. sp. — Obloiig-oval, black, densely clothed with small, dirty 

 gray oval scales, mottled each side of the suture with dark brown. Beak ( % ) 

 moderately stout, curved, of nearly equal thickness throujihout, densely punc- 

 tured, striate, thinly sctily from base to the insertion of the antennse, basal tufts 

 distinct: (?) a little more slender, longer and shining. Antenna not very slen- 

 der, inserted two-fifths ( 9 ) or less than one-third { % ) from the apex; second 

 joint of funicle one-half longer than the third, outer joints wider. Head finely 

 alutaceous, front punctulate, scaly. Prothorax one half wider than long, slightly 

 narrowed anteriorly, distinctly constricted at the apex, sides rounded before the 

 middle, nearly straight and somewhat convergent behind, rather closely punc- 

 tured, punctures small, round, distinct, scales dark brown, paler ou the sides, 

 erect setie not obvious. Scutel distinct. Elytra one-third wider at the base 

 than the prothorax, sides straight for more than one-half their length then 

 gradually rounded to the apex ; humeri moderately prominent, rounded ; striae 

 fine, remotely punctured, interspaces fiat, setfe whitish, procumbent and not 

 readily visible, second to fourth or fifth each side interruptedly mottled with 

 dark brown, giving a somewhat scalariforni appearance, a short white basal line 

 on the third and seventh interspaces; postocular lobes broad, feebly prominent, 

 antecoxal ridges not strongly marked. Legs moderately stout, thighs feebly 

 clavate, tibiae rather short, stout, subparallel, widened at the apex, latter rather 

 feebly hooked; tarsi not stout, third joint bilobed, fourth moderately long; 

 claws very small, connate two-thirds their length. Length 2.75 — 3.00 mm. ; 

 0.11—0.12 inch. Plate vii, fig. 15.

Not closely related to any species known to me. The antennje are 

 inserted less than one-third from the apex in the male. It resem- 

 bles mucidus of the preceding group, but differs in the presence of 

 the rather feeble raitecoxal ridges and the dark mottlings along the 

 suture. Considered as obtectus Lee, by Caj)t. Casey, from which it 

 is at once distinguished by its very small tarsal claws, wliich are 

 connate nearly to the apex, the elytra much wider at the l)ase than 

 the prothorax and its larger size. 



S. I^pidus n. sp. — Oblong-oval, dark piceous, the scaly vestiture moderately 

 dense, especially on the underside, scales oval, yellowish, sprinkled with white 

 above. Beak very robust, strongly curved near the base, striate, densely jiunc- 

 tured almost to the apex, a median elevated line, dilated about the insertion of 

 the antennae, not very densely clothed with filiform scales in its basal lialf; 

 basal tufts almost obsolete, constriction not deep; scrobes oblique. Antennie 

 robust, inserted a little before the middle ( % ), second joint of funicle not longer 

 than the third. Head feebly shining, remotely punctulate and scaly. Protho-
