The species can be tabulated as follows : — 



Elytra with two sinuous transverse bands, humeral ring, 



and apical spot of yellowish v/hite pubescence balteatum. 



Elytra sparsely and uniformly pubescent. 

 Posterior third distinctly lighter in color than the re- 

 mainder. Both joints of the antennal club sub- 

 equal ; metasternum finely and sparsely punctate. . hemorrhoidale. 

 Apex only distinctly lighter than remainder. 



Last joint of antennal club much smaller than pre- 

 ceding. Metasternum coarselyand densely punctate, apicale. 

 Elytra uniform in color. Last joint of antennal club 

 smaller than preceding. 

 Thorax finely and densely punctate ; sides nearly 



arcuate and hind angles acute in the male triste. 



Thorax almost smooth ; sides greatly dilated and hind 



angles retracted in the male nificorne. 



C. balteatum Lee. Oval, convex, piceous or fuscous, clothed with 

 moderately long, yellowish, semi-erect pubescence. Elytra marked by 

 two transverse sinuous bands, a humeral ring, and apical spot of longer 

 whitish pubescence. Head coarsely punctate. Antennae fuscous, terminated 

 by a large 2-jointed club. Thorax convex, hind angles acute, moderately 

 finely punctate, pubescence more dense at sides and base. Scutellum 

 small, naked. Elytra coarsely punctate, piceous, sparsely clothed with 

 semi-erect, yellow and black pubescence, with humeral ring, two trans- 

 verse bands, and apical spot of dense whitish-yellow hairs. Body beneath 

 black or piceous, coarsely punctate, covered with fine, long, semi-erect, 

 yellowish-white pubescence. Metasternum moderately finely punctate. 

 Abdomen fuscous, coarsely punctate, densely pubescent. Legs rufous. 



Male. I have not been able to see any males of tbis species. 



Female. Antennal club elongate, made up of two joints, nearly equal, 

 about as wide as long, together equaling all the preceding joints. The 

 club is received into a fossa which occupies only the anterior half of the 

 space between the prosternum and lateral margin, is almost circular, ,and 

 appears to lie transversely. Length .10 inch ; 2.5 mm. (Fig. 44.) 



The distinguishing characters of this species are the coarsely punctate, 

 piceous, fasciate elytra, and the structure of the antennal club. 



The banded elytra give the insect the appearance of a Trogoderma, but 

 the generic characters, already given, serve to separate this species with 

 certainty. 



Occurs in the Pacific States. 



C. hemorrhoidale Lee. Elongate-oval, moderately convex, reddish- 

 brown, clothed with moderately long, yellow, semi-erect pubescence. 

 Elytra reddish-brown, posterior third lighter. Head black, very coarsely 

 and densely punctate, sparsely pubescent. Antennfe light brown. Thorax
