170 THE CANADIAN ENTOMOLOGIST 



It was only through rccei\ing some aptenc from that tree sent by 

 Mr. Britten, from Cumberland, that I discovered this general 

 mistake. 



That the so-called Brown, Blue and Rosy Aphis or Leaf- 

 curling Aphis of the apple in England was not Aphis sorbi was at 

 once seen, for Kaltenbach* clearly stated that the cornicles of the 

 apterous 9 were "blass^elb, an der Spitze liriiunlich," whilst the 

 erroneously called Aphis sorbi has thcni markedly black in all 

 stages. 



Probabh" the presence of the four pre-anal papilla- in both 

 species led Sanderson and others to the conclusion that they 

 were the same. Very similar papilhe, I find, also occur in Kalten- 

 bach's Aphis cratcc^i. 



I ha\'e not attempted to deal with all the known features of 

 the life histories of these insects, nor the full l)il)liograph\-, but 

 merely point out their proper names and the salient features of 

 their bionomics as obser\ed in Britain and the literature examined. 



The Woolly Aphis {Eriosoma lanigera) is not dealt with, how- 

 ever, as I am preparing a special report on this insect in regard 

 to its life in Britain. Several other species have been found on the 

 apple in America; only one of these, so far, is known in Europe, 

 namely, IkocWs Aphis medicaginis, which I ha\e found in England, 

 but which, up to now, has not been noticed on the apf)le. These 

 are referred to in a note at the end of this paper. I also add the 

 description of an undcscribed Apple Aphis from Africa.
