Meade-Waldo (1913) indicated the identity of 7. clypeata with 
abdomen, the 7’. clypeata var. zebra Friese. In Proc. U.S. Nat. 
Museum, 55 (1919), p. 211, I treated zebra as a distinct species, but 
it is perhaps after all only a dimorphic (dischroic) form of c/ypeata, 
as would be suggested by the fact that Mr. Chubb took both at 
Bulawayo on the same day. In that case, since Vachal’s name has 
priority, the form with entirely black abdomen will be 7’. denovtt var. 
clypeata (Friese).
