/ wow AND LITTLE KNOWN BRITISH APHIDES. 183 
Food Plant.—Malva spp. 
Locality.— Wye, Kent, June 7th, 1913. 
Described from several alate females. It is easily distin- 
suished by the pale flagellum. A few small green larve 
surrounded some of the females. It bears some resemblance to 
Koch’s Rhopalosiphum staphylee, but can be distinguished by 
having, in addition to the white apices of the antenne, four, not 
five, lateral abdominal spots, and no dark apices to the femora. 
15. Aphis plantaginis, Schrank. 
This aphis, described by Schrank in 1801 (‘ Fn. Boica,’ ii, 
p. 106), seems to be widely spread over England. It lives on 
the roots and leaves of all plantains (Plantago spp.). On 
October 8rd, 1915, I also received this species feeding on the 
roots and on the neck of carnations just above ground from 
Sheerness. This colony contained many nymphe, and alate 
appeared from October 10th until November 4th. It has also 
been found in the umbels of Daucus carrota and on Viola spp. 
and Chrysanthemum leucanthemum, above ground and on the roots 
of Bellis perennis, Achillea millefoltum, A. ptarmica. I have 
also found it on the lower leaves, and rarely on the flower stalks, 
of Leontodon taraxacum and on the roots of Lychnis dicuna, 
Kumex spp., and parsnips. It is largely attended by ants, and 
has been found by Donisthorpe, Britton, and others in the nests 
of Lasius niger, L. flavus, Formica rufa, EF’. fusca, and Myrmica 
ruginodis. Recorded from Cambridge, 17, v, ’88; Kingston-on- 
Thames, 7, vi, 84; Maidstone, 7, ix, 15; Wye, 2, ix, 12, 2, x, 
"15 (Theobald) ; Bradgate Park, Leicestershire, 8, v, 09; Kew 
Gardens, 24, ii, 10; Rossbeigh, co. Kerry, vi, 02; Weybridge, 
1, x, 710 (Donisthorpe); Wan Fell, Cumberland, 22, ix, ’12 
(Britton). The oviparus 2 occurs in October, and was found in 
the earth with ants, who look after the black ova. This @ is 
greenish, legs with femora, apical third of tibiz and all the tarsi 
of fore and mid legs dark; hind legs all dusky, the tibiew broadly 
expanded, narrower near apex, with many sensoria on the basal 
two-thirds. Antenne of five segments, shorter than the body, 
last two segments dusky; third the longest, nearly as long as 
the last two; fourth about half the length of third ; fifth with a 
long thin nail, rather more than twice the length of the basal 
portion. Cornicles dark and short, about the same length as the 
dark eauda. Anal plate dark. Length 1°2 mm. 
I am not aware that the oviparous female has been described. 
The male I have never seen. 
Fabricius’ Aphis dauci (‘ Ent. Syst.,’ iv, p. 217, 88) is 
synonymous. Neither Walker nor Buchton recorded it from 
Britain.
