74 BRITISH APHIDES. 



Pujpce. 



Pale brown. Head, thorax, and wing-cases green- 

 ish. Abdomen carinated, with brown nectaries. 



Winged viviparous female. 



Wholly shining pitchy brown. Eyes warm brown. 

 Abdomen carinated. Antennse, legs, and anterior 

 half of the cornicles ginger-brown. A strong spine 

 occurs on each side of the prothorax, and a somewhat 

 larger one on each side of the abdomen. Cornicles 

 cylindrical. Tail dark green. Rostrum long, reach- 

 ing beyond the third coxse. Wings ample; cubitus 

 and insertions yellow ; veins brown. 



This insect is variable in size. It is not uncommon 

 from June to August at Norwich, Croydon, and Wal- 

 thamstow, feeding on Lychnis vescaria, L. diurnal and 

 L. vespertina. 



Aphides, also in quantity, were taken by me on the 

 young shoots of the ivy. They entirely agreed with 

 the above-described insect, except in possessing shorter 

 antennjB. The fine setaceous seventh joint of Aphis, 

 however, is so liable to injury that this difi'erence is 

 not, perhaps, of great consequence. Mr. Walker says 

 that the oviparous female is entirely red, and that the 

 male is black and very small. He also gives Aphis 

 cucuhali of Linnaeus for a synonym of A. lychnidis.
