Specimens sent to the Imperial Bureau of Entomology by Mr. Gowdey from Ficus 

 sycomorus at Kampala are clearly the same insect, although the cornicles seem

5. Aphis tamaricis, sp. nov. (tig. 5). 



Alate viviparous female. — Greenish, with dark thoracic lobes. Head almost flat 

 in front, or slightly rounded, broad. Antennae about half the length of the body, 

 greenish ; first segment a little wider than second ; third longer than fourth and 

 sometimes slightly longer than sixth, with 2-3 rather large circular sensoria ; fourth 

 often with a single sensorium, as long as fifth, the latter with an irregular subapical 

 sensorium and often another placed medially ; the sixth very marked, the basal 

 area being longer than the small blunt flagellum ; normal sensoria at junction 

 of basal area and flagellum ; third to sixth segments imbricated. Eyes large.
