long as the body ; in lycopsidis {= suffragans) a little longer 

 than the body. Both have a dark thorax and green abdomen. 



22. Brachecolus stellarice, Hardy. 



So far this Aphid has only been recorded from the north of 

 Britain. 



On August 10th, 1916, Mr. E. E. Green sent me galled 

 leaves and leaf-tufts of Stellaria, sp. ? from Camberley swarming 

 with this Aphid. The leaves were bent upwards at their edges 

 forming boat-shaped galls, so many at the apex of each plant 

 that dense deformed tufts resulted. The infested leaves are 

 paler than normally, some reddish and slightly swollen in 

 patches, along each side of the mid-rib. The insects were 

 mostly immature apterae of a pallid green colour, the young 

 covered slightly with white meal or fine down. They were 

 readily shaken out of the galled leaves. 



23. Macrosiphum loti, Theobald. 



This green Macrosiphum, which I described from a few 

 apterse taken on Lotus corniculatus in July and August at Wye 

 (• Trans. Sec. Ent. Congress,' p. 384, pi. xiv, fig. 2 a, 1912), has 

 also been found at Bulverhithe, near Hastings, in Sussex, and 

 has been sent me, I find, by Mr. Britten from Great Lalkeid in 

 Cumberland; and from the two latter localities the alate female 

 was described (' Journ. Eco. Biol.' viii, No. 3, p. 139, figs. 47 

 and 48, 1913). Kecently I have taken this species at Fresh- 

 water in the Isle of Wight (viii, 1915) ; at Brockenhurst in the 

 New Forest (viii, 15) ; and at Little Hadham in Herts (iv, 15). 

 Mordwilko also records this species from Russia and places it in 

 his new genus Acyrtliosiphon (' Fn, d. 1. Piussie,' p. 185, figs. 82 

 and 83, 1914). 



24. Macrosiphum riihifolium , no v. sp. 



Apterous viviparous feviale. — Green ; antennae and cornicles dark ; 

 legs with much dark coloration. Antennae longer than the body, 

 arising from prominent frontal tubercles ; basal segment larger than 

 the second, with several hairs near apex forming a more or less- 

 prominent tuft; third segment longer than fourth, with 14-17 sen- 

 soria, not spreading to the apex, and with stiff clavate hairs ; fourth 

 and fifth about equal, with simple hairs ; sixth long. Eyes dark. 

 Proboscis green, dark at apex, reaching to the base of the third pair 

 of legs. A small pale lateral tubercle on each side of the pronotum, 

 and two small ones each side between the second and third legs. A 

 few prominent hairs over the abdomen and on the head. Cornicles 

 dark, very long, more than one-third the length of the body, curved out- 

 wards and projecting well beyond the cauda ; apex markedly reticulate,, 

 remainder imbricated ; in some the cornicles are deep brownish-green, 

 paler just at the base, in others quite black. Cauda pale green to
