AMERICAN COLEOPTERA. 441 



slightly convex, rugose, posterior callus feebly muricate. a large scutellar spot of 

 pale scales; pygidiuni strongly carinate, sterna densely, abdomen more remotely 

 and not deeply punctured, clothed with white scales, more dense on the sternal 

 side pieces. Legs slender, pubescent, femora sul)clavate, tibise parallel, a little 

 widened at the apex, tarsi not slender, first joint a little elongate, following two 

 joints equal in length, third broadly bilobed, fourth projecting the length of the 

 third joint, claws with a small basal tooth. Length 2.0-2.2 mm. ; 0.08-0.09 inch. 



% . Fovea of last ventral segment large, deep and sharply defined. 



9 • Last ventral segment with smaller, rounded and less sharply defined fovea. 



Hub. — Western and Southern States, Colorado, Wyoming, Oregon, 

 Vancouver, British Columbia. 



Numerous s})ecimens are before me. Dr. LeConte describes the 

 claws as being simple, they are nevertheless toothed, the tooth being- 

 very small and readily overlooked. The elytra are more or less red- 

 dish brown, at least so, in their a])ical portion, entirely so in some 

 specimens with the exception of a triangular basal space. 



C adspcrsuliis n. sp. — Oblong oval, dark brown, antennaj. legs and apex 

 of the elj'tra rufous, above thinly clothed with hair-like pubescence, interspersed 

 with large, oval, white scales; underside densely scaly, scales elongate, piliform. 

 Beak long, curved, striate and punctured towards the base, shining and puuctu- 

 late beyond the insertion of the anteunte, the latter slender, inserted at the mid- 

 dle ( % ), or before it ( 9 ). joints 3-4 of funicle subequal, outer joints gradually 

 wider, club oval, acuminate. Head densely punctured and pubescent, front 

 squamous ; prothorax more than one-half wider than long, one-third wider at the 

 base than at the apex, strongly rounded on the sides and deeply constricted behind 

 the apical margin, lateral tubercles transverse, not prominent, dorsal channel ob- 

 solete on the disc: disc evenly and closely punctured, punctures small, ocular 

 lobes broad, not prominent, ai)ical margin elevated, base nearly straight each 

 side ; sides, apical constriction and median line more densely clothed with white 

 scales; scutel small, glabrous. Elytra longer than wide, one-fourth wider at the 

 base than the prothorax, not markedly narrowed posteriorly, strife fine, punc- 

 tures small, remote, interepaces rugose, posterior callus with a few acute granules, 

 a scutellar spot of white scales; femora and tibise at in pusio, tarsi slender, joints 

 1-3 gradually shorter, fourth joint long and slender, projecting about twice the 

 length of the third, claws with a short basal tooth. Length 2.4 mm. ; 0.11 inch. 

 % . Ventral fovea rather deep. 



Hab. — California, Arizona. Dr. Horn's and Nat. Mus. coll. 



Closely resembles the preceding species, but is less narrowed in 

 front and behind, the prothorax more strongly rounded on the sides 

 and more finely punctured, the j)ubescence is finer and longer, the 

 tarsi more slender with the fourth joint much longer than the third. 

 The white spots on the elytra consist of single, large scales, instead 

 of an aggregation of scales as in ])imo. Dr. Horn's specinun lias 

 the sutural s})ot prolonged as a sutural line.
