ring. The cenchri are white; the fifth abdomiual segment is also 

 white; the attachment of the following segment shows through as an 

 indistinct ring; coxae and femora blue-black, the anterior knees red- 

 dish ; tibiae red, those of the posterior legs white at the base; tarsi 

 red, with brown claws. The stigma of the wings is blackish, with a 

 white base ; the wings themselves are somewhat smoky. 



Besides being smaller the male differs from the female in having the 

 fifth abdomiual segment black, and in the absence of the white base 

 to the hinder tarsi. 



1 have not observed the act of ovipositing, but in the month of 

 August I found some eggs on a rose-leaf stowed away in little bags on 

 the leaf, the skin on both sides of these little bags being brown. 

 From these eggs proceeded little caterpillars of a gray colour, with 

 black heads (see fig. 9 b) ; they ate holes from the under side of the 

 leaves to the upper, and, botli in appearance and the manner in which 

 they lay rolled up, entirely agreed with the larvoe just described. 

 1 left them in the open air, where they were unfortunately washed off 

 or killed by the rain and wind. I conclude these little larvae were 

 those of our species, and have therefore given a figure of them on this 

 plate. The claws of this insect are remarkable ; one is represented 

 at fig. 10: they consist of three moderate-sized crooked and rather 

 blunt tceil), united together into a sort of comb. Each foot has two 

 such diverging little combs. 



Notes on Aphides. By Francis Walker, Esq., F.L.S. 

 (Continued from Zool. S. S. 1333). 



Myziis Cerasi (S. S. 1121). — The male of this species appears in October. It is 

 black; ibe aiitennx are much longer ihan the body, and the joints except the seventh 

 are slightly incrassatcd ; the nectaries are nearly onc-fourih of the Jentjlh of the body ; 

 the legs are long and slender; the femora and tibiae dark green, black towards the 

 tips; the wings are t«\ice the length of the body, the stigma black. 



M. Persiccc (S. S. 1121). — I wish to call attention to the characters by which 

 Passerini distinguishes Myzus Persica;, Passerini, from Ajjhis Persicse, Fonscolombe. 

 The latter abounds on peach trees in England. The autenux on a frontal tubercle 

 distinguish Myzus from Aphis. 



M. Lychnidis (S. S. 11-22).— It is remarkably abundant in the Channel Isles, and 

 I have also found it in the I.sle of Man. Passerini mentions two species of Aphidins 

 that infest the Lychnis; I have only observed one in En^jland. 



M. Oxyacanlfice {S. S. 1122). — It appears in July, and the following description 

 refers to the apterous female. Pale green, shining, nearly elliptical, very finely
