convex, moderately finely punctate, pubescence long and yellow. Scutel- 

 lum naked and rough. Elytra black as far as the posterior third, -which 

 is piceous or rufous, very sparsely pubescent, coarsely and moderately 

 densely punctate. Body beneath black, coarsely, except the metasternum, 

 which is finely punctate ; pubescence long and yellow. Legs with thighs 

 rufous, tibiae and tarsi lighter. Length .09 inch ; 2.1 mm. 



Male. Antennal club very large, composed of two sub-equal joints, 

 almost disc-shaped, and twice as long as the preceding segments united. 

 (Fig. 45.) 



Female. Antennal club of two sub-equal joints, together only as long 

 as all the other joints united. (Fig. 46.) 



Tlie important characters which enable us to separate this species are, 

 the constant light color of the posterior third of the elytra, the oval anten- 

 nal club of two sub-equal joints, and the finely punctate metasternum. 



Occurs in the Southern and Western States. 



C. apicale Mann. Elongate, convex, black, sparsely clothed with 

 moderately long, yellowish, semi-erect pubescence. Head coarsely punc- 

 tate, sparsely pubescent. Antennae light brown. Thorax with hind angles 

 acute, black, finely and densely punctate, pubescence sparse. Scutellum 

 small, scabrous, naked. Elytra black, apex rufous, coarsely punctate, 

 pubescence sparse, yellow and black ; apex usually clothed with dense 

 yellow hairs. Body beneath black, moderately coarsely punctate, sparsely 

 pubescent. Metasternum very coarsely punctured. Abdomen black or 

 piceous. Legs rufous, tibife, etc., lighter. Length .11 inch ; 2.3 mm. 



Male. Antennal club elongate, of two joints, the last of which is half 

 as long as the preceding, together twice as long as all the others united. 

 Club received into a fossa which extends almost to the posterior angle of 

 lateral space. (Fig. 57.) 



Female. Antennal club as in male, but only half as long ; the fossa 

 occupies only the anterior half of the lateral space. (Figs. 58, 59.) 



The prominent characters of this species, are found in the apical color 

 of the elytra, the coarse puncturing of the metasternum and the elongate 

 antennal club, composed of two unequal joints. 



Occurs in California. 



C. ruficorne Lee. Sub-oval, convex, black or piceous, clothed with yel- 

 lowish semi-erect pubescence. Head coarsely punctate, pubescence sparse 

 and yellow. Antennae very light, almost testaceous. Thorax convex ; 

 in the male the lateral margins are strongly dilated over the antennal 

 fossae and the hind angles are retracted, very finely and sparsely punc- 

 tured, pubescent at sides. Scutellum naked, black. Elytra piceous, 

 coarsely ])unctured, clothed with sparse yellow and black hairs. Body 

 beneath almost black, coarsely punctured, sparsely pubescent. Metaster-
