C. lioruii n. sp. PI. xiii, fig. 25.— Oval, black, depressed, above glabrous, very 

 thinly i)iibescent, underside densely and finely punctiired and clothed with elon- 

 gate, white scales. Beak moderately .slender, curved, very little longer than the 

 protliorax (% ), .striate and punctured beyond the middle, shining near the apex, 

 scrobes parallel, nearly straight, widened posteriorly; antennse slender, inserted 

 just before the middle, first and second joints of funicle elongate, former stouter, 

 joints 3-4 shorter, equal, outer joints scarcely wider, club large, ovoidal, acumi- 

 nate. Eyes round, somewhat convex, not entirely concealed by the feeble post- 

 ocular lobes. Head densely i)unctured, pubescent, front concave; protliorax one- 

 half wider than long, nearly two fifths. wider at the base than at the apex, well 

 rounded on the sides and deeply constricted behind the apical margin, the latter 

 elevated lateral tubercles in form of an elevated transverse ridge, concave on its 

 anterior face, dorsal sulcus entire, ill-defined on the disc and ending in a fovea 

 anteriorly, surface densely punctured, jjunctures large, superficial, basal margin 

 straight; scutel elongate, glabrous. Elytra one-third and rather suddenly wider 

 at the base than the prothorax, sides feebly rounded, subparallel for three-fourths 

 their length, then strongly rounded to theai)ex, stria; sharply defined, not deeply 

 impressed, closely punctured, interspaces wide, each with a row of large, acute 

 tubercles, tubercles directed backward and bearing on their posterior fa(^e near 

 the summit a straight and nearly horizontal seta, sutural interspace with a line 

 of white scales, its outer half with a row of smaller tubercles; pygidium perpen- 

 dicular (%), slightly inflexed and rather large, punctured ; anterior coxse nar- 

 rowly separated. Legs long, femora scarcely clavate, mutic, tibia; slender, grad- 

 ually widened towards the apex, tarsi slender, first and second joints elongate, 

 third broadly bilobed, lobes long, fourth joint long and slender, projecting the 

 length of the preceding joint, claws armed with a small, obtuse, basal tooth. 

 Length 3.0-3.2 mm. : 0.12 0.13 inch. 



%. Last ventral segment deeply foveate, fovea circumvallate in its anterior 

 half, tibiie unguiculatc. 



Hab. — Southern California. Three males, Dr. Horn's coll. 



Different from any Ceutorhynchid known to me, and at once 

 recognized by its glabrous, strongly tuberculate elytra and white 

 sutural vitta. I dedicate this species, with pleasure, to my friend, 

 G. H. Horn. 



C nodi pen II is n. sp. — Oval. depre.ssed, black, densely clothed above and 

 beneath with large, grayish white, or pale ochreous scales. Beak slender, about 

 as long ('^ ), or much longer ( J) than the prothorax, cylindrical ; finely punc- 

 tate and striate toward the apex and squaraose in its basal third, remotely punc- 

 tulate and shining beyond in the female; antennse slender, inserted just before 

 the middle ( % ), or one-third from the base ( 9 ). first two joints of funicle elon- 

 gate, first very little stouter than the second, joints 3-4 equal, outer joints a little 

 wider, club large, ovoidal, acuminate. Eyes not entirely concealed by the fairly 

 well developed, prothoracic lobes. Head convex, densely scaly ; prothorax wider 

 than long, a trifle over one-fourth wider at the base than at the apex, sides broadly 

 constricted behind the apical margin, the latter elevated, feebly emarginate at the 

 middle, lateral tubercles transverse, prominent, dorsal channel evident, but like the 

 punctures concealed by the crowded, piliform scales, base broadly emarginate each 

 side : scutel scarcely visible. Elytra one-third and rather suddenly, wider at the
