der, first and second joints elongate, third broadly bilobed, fourth shorter than 

 the two preceding joints together and projecting as much as the length of the 

 fourth, claws rather large and armed with an acute, basal tooth. Length 2.5- 

 2.75 mm. : 0.10-0.11 inch. 



Hub. — Santa Rosa County, California (Dr. Horn), San Francisco 

 County (Nat. Mus. coll., Ulke), Kansas (Ulke). 



This species varies considerably in appearance, according as the 

 larger scales are present or not. A specimen in Mr. Ulke's collec- 

 tion from Kansas has the thoracic punctures larger, but does not 

 differ otherwise. Another specimen in the same collection from 

 California differs by its smaller size (2.25 mm. J and the suberect 

 scales on the elytral interspaces arranged in a single row. 



C. ovalis n. sp. PI. xiii, figs. 26, 26rt, 266. — Oval, convex, dark piceous, 

 above thinly clothed with fine, brownish pubescence and scattered, large, oval, 

 white scales, a scutellar spot and sutural vitta of similar scales, underside densely 

 clothed with large, oval, white, or yellowish white scales, especially crowded on 

 the sternal side pieces. Beak not very slender, curved, finely striate and punc- 

 tured from the base to the insertion of the antennae, remotely punctured and 

 shining toward the apex, antennae not very slender, inserted a little beyond ( % ), 

 or at the middle ( 9 )> club elongate acuminate. Eyes nearly covered in repose 

 by the prominent prothoracic lobes. Head densely punctured, front flattened ; 

 prothorax wider than long, narrowed from the base, the latter one-third wider 

 than the apex, not strongly constricted at the apex, sides broadly rounded, apical 

 margin elevated, feebly emarginate, base nearly straight each side with the aute- 

 scutellHr lobe rather prominent, lateral tubercle obsolete, surface closely and finely 

 punctured, dorsal channel entire, wide and more deeply impressed near the base ; 

 sides, anterior impression and median hue, clothed with white scales; scutel very 

 small, scaly. Elytra oval, convex, a little more than one-fourth wider at the base 

 than the prothorax, sides rounded, striae fine, impressed with a row of minute 

 scales, which conceal the closely placed punctures, interspaces wide, flattened, 

 rough, a few, very minute, though acute granules on the declivity; pygidium 

 and underside densely punctured ; femora subclavate, tibiae widened to the apex, 

 feebly curved, tarsi rather stout, the second and third joints together, longer 

 than the fourth, which projects about the length of the preceding joint, the latter 

 broadly bilobed, claws small, with an acute basal tooth. Length 2.75-3.0 mm. ; 

 0.11-0.12 inch. 



Hah. — Illinois, Minnesota. Three specimens, Nat. Mus. and Mr. 

 A. Bolter's collection. 



A very distinct species which may be readily recognized by its 

 size, oval convex form and conspicuous sutural vitta. 



C iiitcriiioclius n. sp. — Oblong, black, somewhat depressed, above clothed 

 with small, white and pale brown scales, interspersed with scattered, large, white 

 scales, underside densely covered with large, dirty gray scales. Beak long and 

 slender, curved, shining almost throughout, finely punctulate toward and scaly 

 at the base ; antennae not very slender, inserted one-third from the base ( 9 ), 

 outer joints of funicle widened, club large, elongate, acuminate. Head densely
