This minute species is perhaps the one mentioned by 

 Haliday as a var. of salicis (sp. 31). After examining a 

 great number of both species, I have no hesitation in 

 keeping them apart. A. dauci is a parasite of Siphonopliora 

 jpastinacas, which infests Pastinaca sativa, the parsnip, and 

 Apium graveolens, wild celery. The Bignell collection con- 

 tains a series bred out of the same pucerons, but taken on 

 Daucus carota, the carrot, and Crithmum maritimum, 

 samphire.
