C piisilluN Lee. — ObloDg, depressed, reddish brown to dark piecous. legs 

 always ferruginous, beneath densely clothed with gray scales, above thinly clothed 

 with pale, scattered scales, each elytral interspace with a row of erect, rigid setae. 

 Beak a little longer than the prothorax, cylindrical, feebly curved, finely carinate, 

 punctured and striolate near the base, shining and remotely punctulate beyond 

 the insertion of the antennae, the latter inserted a little before the middle {% 

 and 9)> slender, outer joints of funicle not wider, club large, ovoidal-acuminate 

 Eyes flattened, only partially concealed by the feeble, prothoracic lobes. Head 

 densely punctured, front slightly concave; prothorax wider than long, gradually 

 narrowed from the base and feebly rounded on the sides, constricted at the apex, 

 apical margin elevated, entire, lateral tubercles small, acute, dorsal channel en- 

 tire, wider towards the base, disc densely punctured, each puncture bearing a 

 short hair on seta, a line each side and along the middle, of pale scales; scutel 

 very minute. Elytra oblong, a little wider at the base than the prothorax. 

 scarcely narrowed for three-fourths their length, then rapidly rounded to the 

 apex, sides very little rounded, striai deep, closely punctured, interspaces a trifle 

 convex, rugose, with a row of fine, equidistant, setigerous punctures, declivity 

 with a few, very small, acute granules, an ill-defined scutellar spot of pale scales ; 

 pygidium small, convex ( % ), or scarcely visible between the elytral apices ( 9 ) ! 

 femora feebly clavate, tibiae a little widened towards the apex, tarsi very slender, 

 third joint not broadly bilobed, fourth long, projecting more than the length of 

 the third, claws armed with a long, acute tooth. Length 2.0 mm. ; 0.08 inch. 



% . Ventral fovea profound, rounded. 



Hab. — California. 



Dr. Horn's, Nat. Mus. and ray own coll. More closely related to 

 jxiuxillm and convexicollii . It differs from pauxillus by its some- 

 what larger size, elongate, oblong form, more or less reddish brown 

 color, from convexicollis by its more elongate form, less strongly 

 rounded prothorax, hair-like setre, and especially by the more elon- 

 gate antennal club. 



The scales on the upper surface are easily abraded, giving the 

 insect a hirsute appearance. 



C pauxillus n. sp. — Oval, convex, dark piceous, tibiae and tarsi paler, be- 

 neath clothed with dirt-colored scales, above sparsely clothed with pale scales, 

 elytral interspaces with a row of stifl", suberect setae. Beak feebly curved, not 

 very slender, shining, finely punctured, striate and scaly towards the base; 

 antennae slender, inserted at the middle (%), or immediately before it (J), 

 outer joints of funicle a little wider. Eyes covered about one-half in repose 

 by the feeble prothoracic lobes. Head densely punctured, front flattened or a 

 little concave, squamous; prothorax one-half wider than long, strongly nar- 

 rowed in front, well rounded on the sides, apex broadly constricted, apical margin 

 elevated, not emarginate, lateral tubercles rather large, acute, dorsal channel 

 narrow, ill-defined, obsolete on the disc, the latter rather coarsely though not 

 very closely punctured, base bi-emarginate; scutel visible. Elytra fully one- 

 fourth wider at the base than the prothorax, a little longer than wide, narrowed 

 behind, striae wide, deep, very closely punctured, punctures small, intei-spaces 

 convex, with a row of setigerous jiunctures; pygidium coarsely punctured;
