This group is nearly related to Melandrya (pi. 155), and if 

 broken up it must be formed into many genera : C. 7iigra is a 

 broad insect with the joints of the tarsi and antennae abbre- 

 viated ; C. murina is similar in form ; C.fidvipes and castanea 

 have the anterior and intermediate tarsi a little dilated; in 

 C. ceramhoidcs they are elongated and slender, and the an- 

 tennae are serrated in the male ; and in C. sulphurea and bicolor 

 the palpi are dissimilar in the sexes, those of the male being a 

 little dilated. The larva of C nigra and ceramhoides live in 

 decayed oak-trees, and are described and illustrated in the 1st 

 vol. of the Ent. Trans. ; and the larva and pupa of the former 

 are figured in Germar's Mag., vol. ii. tab. 1, but they do not 

 agree in form.
