tures closer at the middle, very sparse laterally but attaining the sides. Eighth 

 antennal joint about two-fifths longer than wide, triangular, the apical edge 

 oblique. Front tibiae bisulcate; middle tibiae with strictly marginal groove. 

 Length 2.2-3.2 mm. 



Hab. — California (Pomona, Pasadena, San Diego, San Bernar- 

 dino County). 



The elytral vittse are at best feeble, but are visible with a fairly 

 good glass, except in one or two of the very darkest specimens. 



31. C longulum n. sp. — Dark brown, one-half as wide as long, parallel, 

 not at all gibbous in profile, pubescence fine and sparse. Coarser punctures 

 scarcely visible on the head, present in moderate numbers at the sides of the 

 pronotum and on tbe elytra, but small and inconspicuous. Metasteruum finely 

 punctured throughout, the punctures a little larger and closer at the middle, 

 widely separated at the sides. Eighth antennal joint about one-third longer 

 than wide, parallel for a short distance at apex, the apical angle nearly right. 

 Front tibiae bisulcate; middle tibiae sulcate. Length 2-2.2 mm. 



Hab. — Arizona. Described from four examples taken by Barber 

 and Schwarz at Williams and Bright Angel. With these is inclu- 

 ded a nearly identical specimen taken by the same collectors at 

 Las Vegas, New Mexico. The narrow form and elongate metaster- 

 uum readily separate this species from the otherwise allied species. 



32. C. uiiiforme n. sp.— Fale brown, oblong-elliptical, not gibbous in pro- 

 file, pubescence moderate. Coarser punctuation obsolete on the head, visible but 

 sparse, fine and inconspicuous at the sides of the pronotum and throughout the 

 elytra. Metasternum finely sparsely punctate from side to side. Eighth an- 

 tennal joint very nearly twice as long as wide, the terminal edge strongly 

 oblique, the apical angle obtuse. Front tibiae bisulcate ; middle tibiae finely sul- 

 cate along the posterior margin. Length 4 mm. 



Hab. — New Mexico (Mesilla Park ?). One specimen bearing 

 the following legend : "In garden, March 14, in pith of dead sun- 

 flower stem." The specimen was collected by Cockerell and sent to 

 Mr. Wickham from whom I received it. 



33. C. fastigiatum n. sp. — Brown, oblong-elliptical, a little more than 

 half as wide as long, not gibbous in profile ; pubescence fine, rather sparse. 

 Coarser punctuation fine and indistinct on the head, fine but more distinct at 

 the sides of the pronotum, moderate on the elytra, becoming close and strong 

 toward the apex. Metasternum punctured finely from side to side, very sparsely 

 laterally, more closely at middle. Head obtusely, vaguely, longitudinally cari- 

 nate. Eighth antennal joint about one-third longer than wide, subparallel at 

 apex. Front tibiae bisulcate; middle tibiae with a sharply defined marginal 

 groove. Length 2.5-2.9 mm. 



Hab. — Texas. Several examples in Hubbard and Schwarz col-
