t The species are thus distributed: — 1. Tibiae without flying-hairs; 

 prothorax, together with the under surface of the body and the thighs, 

 with flying-hairs ; the first five joints of the antennae with a few scattered 

 stiff hairs underneath ; prothorax longer than broad, the middle part 

 broadest, the sides steeply arched : <? , hind thighs reaching the extremity 

 of the elytra; $ , hind thighs not reaching the extremity of the elytra: 

 (a) forehead vaulted, with a broad, sulcated, longitudinal keel ; antennae 

 filiform (C . liciatus) : (b) forehead flatly depressed; antennae setiform, 

 obscurely dentated (C. arcuatus, C. detritus). 2. Fore and middle tibiae 

 with long flying-hairs on their hind side ; head, prothorax, base of elytra, 

 underside of the body and back side of the thighs with long flying-hairs; 

 antennae thicker at top, the first five joints showing on the under surface 

 a few scattered long bristles ; prothorax as broad as long, broadest in the 

 middle; forehead flat (C. arietis). 3. All three pairs of tibiae with long 

 flying-hairs at their hind side; head, prothorax, base of elytra, under side 

 of the body and back side of the thighs with long flying-hairs ; antennae 

 setiform, first seven joints with a few long scattered bristles on their under- 

 side ; pronotum broader than long, broadest before the middle ; forehead 

 flat (C. mysticus).
