This and the two following species are extremely closely allied and perhaps 
should be classed together. Larger series and a closer study are, however, 
required, There is sometimes in C. grahami a more or less distinct rim of white 
scales to the eyes, recalling that of Protomelanoconion fuscum.

17. C. zombaensis, Theo., Mon. Cul. I, p. 143 (1901). 
C. quasiguiarti, Theo., Mon. Cul. V, p. 374 (1910). 
C. quasiguiarti may be distinct, but I can see no character to separate it 
from C. zombaensis.

If the males described as C. aquilus do not belong to this species, there is no

C. bostocki, Theo., J. Econ. Biol. I, p. 29 (1905). 
The type of C. bostochi has been lost, but the description leaves practically no 
doubt that it was only C. salishuriensas, 
S. Rhodesia ; Transvaal; Natal.
