 disc closely and rather coarsely punctured, each puncture bearing a coarse, scale- 

 like hair, sides clothed witn pale scales; scutel minute. Elytra subtrapezoidal, 

 less than one-third wider at the base than the prothorax, humeri oblique, promi- 

 nent, feebly rounded on the sides and slightly narrowed posteriorly, declivity 

 rather precipitous, muricate, striae not deeply impressed, punctured, each punc-

 middle pair. 



Hab. — Portland, Oreg., Idaho (collected by F. H. Wickham). 

 Dr. Horn's and ray own collection. The two specimens from Idaho 

 differ somewhat from the above description ; upper surface more 

 densely scaly, scales more yellowish and intermixed with white scales, 

 the dorsal channel is wider and more deeply impressed. 



C siculns n. sp. PL xiv, fig. 27. — Oval, rather convex, blackish, antennae 

 and legs rufo-testaceous, beneath clothed with small, whitish or cream-colored 

 scales, the latter especially on the sternal side pieces, above clothed with a fine, 

 white or pale brown, squamiform pubescence inteimixed with larger white scales. 

 Beak rather stout, curved, scarcely as long as the prothorax ( % ), finely carinate, 

 punctured, striolate, pubescent throughout; antennae slender, inserted two-fifths 

 from the apex {%), first two joints of funicle elongate, first joint stouter, outer 

 joints scarcely wider, club large, elongate, pointed. Head densely punctured, 

 coarsely pubescent, front flattened ; prothorax wider than long, strongly nar- 

 rowed in front, rounded on the sides and constricted at the apex, ocular lobes 

 well developed, apical margin elevated, emarginate at the middle, lateral tuber- 

 cles small, acute, dorsal sulcus entire, of equal width, not deeply impressed, basal 

 margin straight, disc closely punctured, sides clothed with pale scales; scutel 

 minute. Elytra scarcely longer than wide, more than oue-fourtli wider at the 

 base than the prothorax, feebly rounded on the sides and gradually nairowed 

 behind for three-fourths their length, then suddenly narrowud to the apex, striae 

 fine, punctures small, each bearing a white, piliform scale and more or less con- 

 cealed by the scaly vestiture, interspaces slightly convex, rugulose, a few very 

 small, acute granules on the summit of the declivity, the latter rather precipitous, 

 an oblique spot extending from below the humerus on the ninth interspace to the 

 sixth interspace inclusive, another spot near the base on the fourth, and another
