Apterous Viviparous Female. — Ven' similar in colour to the 

 two former, but usually a paler green, the antennœ relatively 

 thicker, the fourth segment nearly as long as the third, the 

 fifth as long as the fourth, no sensorium on the third. 



Found on Trifolium prociimhens the first week in August, 

 breeding in small numbers amongst the flower-heads at Wye 

 and Hastings. I also transferred these to peas, but the colonies 

 soon died out. 



Group B. 



Species 4. MacrosiphiDH uhnaricB Schrank (PI. XI\', figs. 3 

 and 6). 



Winged Viviparous Female. — Various shades of green with 

 mealy coat in most cases. The head, antennie, legs, and cornicles 

 slightly darker than in pisi. The green legs have a larger dark 

 area at the apices of the femora and tibiie, and the tarsi dark. 

 The ensiform cauda is pale yellowish green, and the cornicles 

 are relatively thicker than in pisi ; moreover, their dusky apices 

 are markedly reticulate, and there are some apparent transverse 

 lines below, but no imbrication. 



The third antennal segment has a line of sensoria varving 

 from 14 to 19 on one side; remaining segments without any 

 sensoria. 



Length. 2 to 3 mm. ; wings 9 "2 to 9 '8 mm. 



Apterous Viviparous Female. — Green of various pale shades, 

 often with a mealy coat. Antennae about as long as the body, 

 apices of third, fourth, and fifth, and all the sixth segment dusky, 

 fourth slightly shorter than the third, fifth about ecjual to the 

 fourth, no sensoria on the third. Cornicles green, duskv at 

 the apex, showing faint reticulation. Cauda pale yellowish 

 green, shorter and blunter than in the alate female. Legs all 

 yellowish green, except the tarsi. 



Length. 25 to 3 mm. 



Nymph. — Like the above, the wing-tips being slightK' dusky. 



A pink variety occurs side by side with the green and produces 

 exactly the same winged females. The only dift'erence is that 

 in the pink forms the apices of the tibi;e are dusky. 



This species I have found in many places in Kent, Sussex,
