past the second coxae, dusky at the apex, last segment narrow, the penultimate 

 rather broad. Length, 1*5-2 mm. 



British East Africa : Njoro, 16. i. 12 (T. J. Anderson). 



Food-plants : Cape Tomato and Rape. 



Described from several mature apterous viviparous females and some immature 

 forms, also one nymph, in which the wing-cases are very large and darker than 

 the rest of the body, the cornicles and antennae relatively shorter and the pale 

 green tail triangular, as seen in the immature females. The apical swelling of 

 the cornicles varies to some extent. 



Specimens sent from Rape agree exactly with those sent from the Cape 

 Tomato.

In America, Clarke has described an aphis from tomatoes as Necta.ro phor 'a 

 lycopersici (Canad. Ent. xxxv, p. 253, 1903), but the antennae of the species 

 described here do not agree with those of the American species. 



Macrosiphum neavei, sp. nov. 



Apterous viviparous female. — Reddish brown ; antennae about as long as the 

 body, pale reddish brown, two basal segments dark ; legs with the apices of the 

 fore femora, and most of the mid and hind, dark brown, fore and mid tibiae 

 dark at the base and apex, hind with apical half and the base dark ; tarsi 

 dark ; femora with a few stiff hairs ; tibiae with many hairs. Cornicles, cauda 

 and anal plate black. Body with stiff moderately long hairs arising from 

 distinct tubercles, slightly darkened. Eyes black. Basal segment of the 

 antennae much broader and slightly longer than the second, both dark and with 

 a few stiff hairs ; third segment longer than the fourth, rather swollen towards 

 the base, with several hairs on the inner border, three or four on the outer ; 

 fourth and fifth segments nearly equal, the two together a little longer than 

 the third, both with a few stiff hairs, the fifth with a sub-apical sensorium ; 

 sixth nearly as long as the third, fourth and fifth, basal area short ; fourth to
