7. €'. grande n. sp. — Brown, almost twice as long as wide, oblong-elliptical, 

 not gibbous in profile, finely pubescent. Intermixed coarser punctures virtually 

 wanting on the head, moderately numerous though rather fine at the sides of the 

 pronotum, distinctly larger and moderately numerous on the elytra where they 

 tend to become condensed in longitudinal bands, especially laterally. In certain 

 lights the sides of the elytra are seen to be vaguely subsulcate. the line of punc- 

 tures occupying these feeble impressions. Lateral striae lacking. Metasternum 

 finely punctured at middle, scarcely at all so at sides. Eighth antennal joint 

 nearly one-balf longer than wide, triangular, with outer apical angle rounded, 

 the apical edge oblique. Front tibiae bisulcate, middle tibiae sulcate. Length 

 3.8-4.8 mm. 



Hab. — Marf'a, Texas ; Shovel Mountain, Texas, " from stems of 

 Yucca," National Museum collection ; Oracle, Bright Angel, Santa 

 Rita Mountains and Williams, Arizona. 



This species attains a greater size than any other of our fauna. 

 It is rather closely related to estriatum, but may be distinguished by 

 the greater development of the coarser punctures and its more elon- 

 gate form. 



8. C. lentuill n. sp. — Closely related to grande, but seems distinct by its 

 smaller size, a trifle less obtusely rounded at extremities; slightly better defined 

 traces of lateral stria?; coarser punctures of elytra, less evidently arranged in 

 geminate series, those of the metasternum' approaching more closely the sides; 

 the hind eoxal plates more evidently punctate, the pubescence distinctly longer. 

 Length 3-3.5 mm. 



Hab. — Prescott, Arizona. Collections, Bowditch and Blanchard. 



9. C. COiiophillim n. sp. — Dark brown, rather less than three-fifths as 

 wide as long. Evenly broadly oblong-elliptical, not gibbous in profile. Coarser 

 puuctuation of upper surface strong and conspicuous throughout. Metasternum 

 rather finely punctate, the punctures extending to the sides. Hind coxa] plates 

 distinctly punctate. Front tibia? bisulcate, middle tibiae sulcate. Length 3.6 mm. 



Hab. — Las Vegas, New Mexico. 



The example before me was collected December 5, 1901, in cone 

 of Pinus edulis by Barber and Schwarz. 



10. C. latum Horn. — Dark brown, broadly oval, strongly convex, scarcely 

 gibbous in profile, finely but rather conspicuously pubescent. Coarser punctures 

 almost entirely absent from head and thorax, very fine and sparse on the elytra 

 where they are almost completely concealed by the pubescence. Lateral striae 

 lacking. Metasternum exceedingly sparsely finely punctured at the sides, the 

 punctures but little closer toward the middle. Eighth antennal joint longer than 

 wide, apical edge distinctly oblique. Front tibiae bisulcate, middle sulcate. 

 Length 2.5-3.8 mm. 



Hab. — Rather plentiful on the sea beaches of southern Califor-
