Near Macon, Georgia; South Carolina. 



1 So written in first description. A typographical error, probably. Dr. Lea after- 

 wards changed the name to oblatus. 



2 Dr. Lea credits this to Ravenel's letter, but neither he nor Ravenel ever described 

 it so far as I know. 



3 Ravenel here credits this species to Lea. Lea's specimens, received from Ravenel, 

 are marked Santee Canal and South Carolina. They are rather thin and delicate, 

 of a peculiar texture, and have a shining brownish green epidermis.
