APHIS CARDUI. ' 93 



dorsum more or less encroacliing on the yellow, so as 

 sometimes to leave only the lateral parts bright. 

 Under side amber, with tip of the rostrum, the cox^, 

 and the anal plate black. 



Pupa. 



Bright green, with yellow carination. Nectaries 

 black. Wing-cases pale green. 



Winged viviparous female. 



Dark olive green or black, shining. Dorsal spot 

 large, irregular, and black, several obscure spots near 

 the carina. Antenna rather long, third joint serrated. 

 Cornicles long, straight, and black. Tail small and 

 obtuse. Legs dark ochreous, with black femoral and 

 tibial points. Rostrum long, reaching beyond the 

 third coxge. Wings brownish, with yellow insertions ; 

 stigma pale ; veins brown. 



Under side fine green, with three large black patches 

 on each side. Anal plate black. 



Aphis cardui of Pass, does not appear to be the 

 same insect as the above. On the other hand, I think 

 it probable that Aphis lata found by Mr. Hardy on 

 Senecio, and described by Mr. Walker (' Zoologist,' 

 vol. viii, Ap. ciii), and A. Jacobcece (Appendix civ, of 

 the same), are the same insects. 



Feeds on Cnicus nutans, Carduus lanceolatus, Anthe- 

 mis maritima, and other plants. 



The Aphis is much destroyed by an Aphidius. 

 Nineteen insects were ichneumoned on a small sprig 

 of Anthemis only one and a half inches long.
