Hab.—Durban (coll. Mrs. Trotter, comm. H. Burnup). 
The type has been presented to the British Museum by Mr. Burnup. 
Belonging to the group of C. fulva (Wood) and C. pustulata (Krauss), 
but may be distinguished from the latter by the fact that the lateral 
areas are quite smooth. Of C. pustulata there is a fine specimen in 
ny British Museum, measuring about three times the length given by 
rauss.
