Egypt : Gizeh and Ghezireh (F. C. Willcocks). British East Africa : Nairobi 

 {T. J. Anderson). — Europe generally and North America. 



Food-plants. — Broad beans, iv.08, iii.09, v.09, Egypt ; berseem and Medicdgo 

 sp., iv . 09, Egypt ; sweet peas, Nairobi. On all culinary and ornamental peas {Pisum), 

 wild everlasting pea (Lathyrus sylvestris), red clover (Trifolium pratense), white 

 clover {T. repens), alsike clover {T. hybridum) and shepherd's purse (Capsella bursa- 

 pastoris), in Europe and America. 



Numerous alate and apterous females of this aphid in Mr. Willcocks' collection 

 and specimens sent by Mr. T. J. Anderson agree exactly with the European green 

 pea louse. This insect, which is destructive in Europe to cultivated peas and 

 beans, and still more so to peas in North America, seems to be very abundant in 

 Egypt, especially on berseem.
