cubitus, and stigma, fine yellow. The other veins 
very fine, and pale brown. Eostrum short, not 
reaching to the second coxse. 
Numerous on the sow-thistle, SoncJius oleraceus, 
at Haslemere, in August. The figures in Plate XXIII 
are of relative sizes.

Long oval, shining, dark brown, pilose, with small

tubercles small. Eyes red. Legs and cornicles rather 
short, brown. Tail rather obtuse. 
Numerous in August under the leaves of the worm- 
wood, Artemisia absinthium. They were taken at Wan- 
stead by the late Mr. Walker, and were identified by 
him as his Aphis absinthii. Although numerous larvm 
came into my hands I failed in obtaining the winged 
female from them. 
Mr. Walker, in the ‘ Annals of Nat. Hist.,’ ser. ii, 
vol. ii, p. 43, gives a long list of synonyms, some of 
which I must think are doubtfully correct. 
Kaltenbach describes the winged female as black, 
shining, and having a brownish abdomen spotted much 
like that of the larva. The wings are pale and the 
costa brownish-yellow. He says that individuals of 
this species are often mixed with those of Aphis 
tanacetaria. 
Koch’s figure of 8. absinthii is very unlike my 
insect.
