 around tlie base of the cornicles. Tlie aiitnnin fbriu has deeji Idaek 

 head and thorax, redilish-lirown abdomen \'i-ilh a diiskv centi'al area, 

 and a dark liand lietween the cornicles. Structrn'ally tliis auliuiiii 

 form ditters frdm the spring' in liaviug no 

 tubercles on the head, and on the seventh 

 and eighth abdominal segments. 



The orijiii rolls fcimilc is pale lenKin- 

 yellow with dusky head, eyes, antenna' 

 and tarsi. The ninh is winged, and has a 

 greenish abdomen marked with black and a 

 dark thorax and narniwer than the winged 

 female. Tliis species hatches aliout the 

 same tinre as ^4. Jifclui, that is, somewhat 

 earlier than A. i:)iiiiil. Two or three bronds 

 occur, and then they leave the apple, flying 

 apparently to a new food plant. Tlie\' 

 disappear during the last week in June until the second week in 

 Tuly. The autunm winged females return in September and Octolier 

 and produce a generation of winged males and wingless oviparous 

 females. The hitter lay their oval, shifiy 1)lack eggs eitlier on tlie 

 spurs, axils of buds, shoots, or on the trunks of the trees. Most, if not 

 all, the aphis eggs found on the trunks belong to this species. 



In (^'airrbridge some years ago this was the only fornr I found, and 

 was considered to be the Ajihis inuli, i.e., ^l. immi, T)e Geer. In 

 Kent it is common, and during lOOC did no little harm to the young 

 leaves. 



The Blossom and Stem Aphis. 



{Aji J I is _ fl tell I i. Sanderson.) 



This also has been taken to be the common Aplils '[idiiii by 

 Ormerod(3), Wliitehead (4), and others in I'.iitain. Yet in 1829, 

 Joshua Major (5) clearly pointed out this species as different from the 

 Leaf Curling Aphis. The specific definition of this lUossom Aphis 

 was made bv i\lr. Dwight Sanderson (6) whose work made me 

 examine the Apple Aphides of tliis country mure clnsely. 



Tliis species I found in Kent in all tlie localities ^^dierc it was 

 sought for but did not seem to be more destiaictive than tlie two
