42 BRITISH APHIDES. 



Found numerously between the seed-pods of the 

 louse-wort, Pedicularis palustris, in the Norfolk fens, 

 about the middle of July. No winged forms could be 

 secured at that time, and I have failed to procure 

 them since. 



Aphis malv^, Walh. Plate XLIX, figs. 1, 2. Walk., 

 Koch, Mosley, Pass.

Body somewhat oval. Head brown between the 

 antennaB ; but sometimes the colour is reddish. Rest 

 of the body yellow or pale green. Legs rather short, 

 pale green ; tarsi darker. Cornicles straight and cylin- 

 drical. Tail but little developed. The vertex and the 

 Cauda pilose. 



Winged viviparous female. 



Much smaller than the wingless female. Head, part 

 of prothorax, and all the thorax, rich brown. Vertex 

 convex, not pointed. Abdomen arched. Rest of the 

 insect fine yellow, with indistinct lateral punctures.
