Palpi much as in A. squamosus, and equally variable. Legs with femur and tibia brindled, the tarsi (except the 5th which is brown in the fore legs and entirely white in the hind legs') broadly banded in alternate dark brown and white. Wings mostly yellow, with spots and blotches of dark brown ; the front edge with two minute specks followed by four spots of dark brown. Scutum with broad, appressed scales. A common African species; also in Palestine. P. H. Bahr infected it experi¬ mentally in Egypt. [A. cinctus, Newstead and Carter, founded on a single Ashanti specimen with broken palpi and hind legs missing, is said to differ from A. pharoensis in having the alternate banding of the tarsals more regular and the 5th tarsal yellow, A doubtful species.] 34.
