•extending beyond the cornicles, which are shorter than the fifth antennal segment. 

 €auda finely spinose, but showing no lateral hairs. The pale proboscis reaches 

 nearly to third coxae. Length, 1 "2-1 "5 mm. 



Food-plant. Pansy. 



Natal : Durban, 1.x. 1912. 



Described from a number of apterous females and some nymphae. Nearly all 

 the females have the posterior portion of the gut, etc., evaginated, giving them a 

 curious ragged appearance. The shape of the body is also marked. 



I have placed this species provisionally in the genus Phorodon on account of the 

 two marked frontal processes and the swelhng on the basal segment of the antennae, 

 but the cornicles and cauda do not exactly fit in with that genus, taking P. humnli, 

 Schrank, as the type. The flattened anal plate occurs, however, in some stages of 

 the hop aphid. 



Capitophorus chrysanthemi, sp. no v. (fig. 4). 



A pterous viviparous female. 



Apparently a pale green or yellow species, with black eyes ; dusky apices to the 

 cornicles and antennae ; tarsi all dark and to some extent the apices of the tibiae ; 

 hairs capitate. Antennae longer than body ; basal segment larger than second 

 and somewhat angulated on the inner side ; third segment much longer than fourth

but not so long as the sixth ; fourth a little longer than fifth, the latter with the 

 usual sub-apical sensorium ; sixth with long flagellum, basal area about one-fourth 

 of the fifth segment. Head 'udth marked frontal lobes and a median raised process ; 

 with two capitate hairs on each lobe, two in front on the median lobe, and 

 two just above them. Eyes prominent, varying from black to deep red or reddish 

 black. Proboscis pale, reaching to just past the second coxae ; apical segment
