third and rather suddenly wider than the piothorax at base and nearly twice as 

 long as wide, sides nearly straight for one-half, thence gradually rounded to 

 apex; humeri prominent; strife impressed, punctured, interspaces about equal, 

 not wide, third wider at the base, suberect setse rather conspicuous; a line on 

 the base of the third interspace and humeri paler. Legs and tarsi as in the pre- 

 ceding, latter a trifle more slender. Length 2.75 — 3.40 mm.; 0.11 — 0.14 inch. 



Hah. — Dakota, Kansas, California. Coll. Dr. Horn and H. Ulke. 



Four specimens before nie ; very closely related to the preceding, 

 if not identical with it ; it differs by the thorax being as long as 

 wide, feebly rounded on the sides and the absence of the smooth 

 thoracic line; the vestiture more dense, and the suberect setse of the 

 elytra longer and more conspicuous. More extended series may 

 establish instability of these characters. 



!>., floi'idsiiliis n. sp. — Oval, pitchy black, legs a little paler, clothed with 

 small, oval, grayish white scales, not dense above and interspersed with dark, 

 brownish scales on the elytra, denser on the underside. Beak not very slender, 

 curved, coarsely punctured and scaly from base to the insertion of the antennae, 

 more remotely punctured, subcarinate with a stria each side, beyond; scrobes 

 commencing about two-fifths from the apex. Head punctured, front scaly. An- 

 tennae rather stout, first joint of funicle fully one-half longer than the second 

 joint: clava ovate, entirely pubescent. Prothorax a little wider than long, 

 rounded on the sides, moderately narrowed in front and not distinctly constricted 

 at the apex ; surface densely and rather coarsely punctured, median smooth line 

 distinct, abbreviated on both ends; a pale, indistinct line each side of disc. 

 Elytra one-third wider than the prothorax at its base and one-half longer than 

 wide, distinctly striato-punctate, punctures distinct, interspaces subequal near 

 the base, finely punctulate and transversely rugulose, setae not evident; humeri 

 and a basal line on third interspace paler. Prosternum not short in front of 

 coxae, transversely impressed, scarcely emarginate, postocular lobes feeble. 

 Legs not very slender, anterior and middle tibiae slightly widened at apex, pos- 

 terior more distinctly incrassate toTard the apex and slightly curved. Length 

 3.75 mm. ; 0.15 inch. 



Hah. — Florida. Two male specimens in Mr. Dike's collection. 



A distinct species, resembling compar in form, but a little smaller ; 

 it differs, aside from coloration, b}' the prothorax being more broadly 

 rounded on the sides and not constricted at tip, the postocular lobes 

 almost obsolete and the prosternum scarcely emarginate. The vesti- 

 ture is less dense than in that species. 



D. coiistrictus Say.^Elongate oval, rufopiceous to pitchy black, clothed 

 with small, oval, grayish or yellowish white scales, not closely crowded on the 

 upper surface, but very dense beneath. Beak long and slender, cylindrical, very 

 feebly curved. Male: moderately robust, opaque, punctured throughout its 

 whole length, more coarsely in its proximate half, scaly and indistinctly tri- 

 caiinate fyom base to insertion of antennae, broadly impressed before the basal
