so near the sides, the latter ciliate with long erect setse ; under surface and 

 legs but, slightly paler. Head much broader than long, coarsely and densely 

 punctate ; sjjarsely punctate near the base, very convex, strongly declivous to 

 the clypeal suture, which is well marked ; clypeus feebly convex, very broadly 

 and strongly sinuate anteriorly ; labrum large, rufous in color ; near the 

 clypeal suture there are several coarse flavate setse. Prothorax slightly more 

 than twice as wide as long, transversely, strongly and evenly convex ; sides 

 feebly convergent from base to apex, distinctly and evenly arcuate; base 

 transversely truncate ; angles — viewed laterally — very slightly obtuse and 

 scarcely at all rounded ; apex strongly emarginate, fringed with flavate set?e ; 

 angles evenly and rather narrowly rounded ; disk irregularly punctate ; punc- 

 tures rather sparse in the middle, coarser and slightly denser near the sides ; 

 base having a fine coriaceous or semimembranous margin. Scutellum minute. 

 Elytra slightly longer than wide, slightly more than twice as long as the pro- 

 thorax ; sides parallel and feebly arcuate for three-fifths the length from the 

 base, together thence evenly and somewhat parabolically rounded behind ; 

 disk very strongly convex, finely rugiilose, rather coarsely and not densely 

 punctate ; punctures evenly distributed, slightly coarser and sparser than 

 those of the pronotum, slightly asperate. Legs rather short and robust ; tarsi 

 slender, first joint of the anterior produced beneath the next three and the 

 basal portions of the fifth. Length 8.8-12.5 mm. 



California (Monterey ; San Pedro). 



The distinguishing features of this species are its large size and 

 peculiarities of pronotal sculpture. In ciliatus the punctures of the 

 pronotum are fine and nearly evenly distributed over the entire 

 disk, while in gr^ossiis they are slightly coarser, and are almost 

 entirely wanting in a broad band, crossing the disk at about one- 

 third its length from the apex, but not attaining the lateral margins. 

 This character is quite constant throughout a series of ten specimens 

 which I have before me. 



C. globosus Lee. — I obtained two specimens of this species at 

 San Diego, California. It may be distinguished from ciliatus and 

 grossus by the very coarse and much denser pronotal punctuation, 

 and the broadly oval form, being even more dilated than grossus. 

 From arenarius it differs in its much denser punctuation and slightly 

 broader form. 



C. arenarius n. sp. — Form rather broadly and evenly elliptical, convex, 

 shining, piceous to piceo-castaneous. Head much broader than long ; clypeus 

 broadly and feebly sinuate at apex ; lateral angles broadly rounded ; suture 

 deep, straight ; surface rather coarsely, densely punctate. Prothorax widest 

 slightly before the base, more than twice as wide as long ; sides strongly con- 

 vergent from base to apex, rather strongly arcuate ; basal angles slightly 

 rounded ; apex broadly emarginate ; disk convex, coarsely, sparsely and
