Aphids, with their parasites and hyperparasites, form a well-defined 

 complex of considerable intricacy. Numerous species of Braconids 

 are internal parasites of Aphids, and their larvae during development, 

 are Hable to infestation by certain Cynipids, Chalcids, and Procto- 

 trupids, which are therefore hyperparasites of the Aphid. 



The origin of primary parasitism is discussed. The successive 

 infestations of a single host by two or more species, or by two or more 

 individuals of the same species of parasite, is sometimes called super- 

 parasitism ; but as this term means the same as hyperparasitism, 

 which is applied to cases where the parasite is itself attacked by another 

 parasite, the word epiparasitism is suggested to replace it ; whilst 

 metaparasitism is intended to designate what has so far been termed 

 accidental superparasitism, i.e., the direct attack of one epiparasite 

 upon another. As these distinctions may be considered too subtle 

 for new nomenclature, the author draws attention to the importance 

 of ascertaining to what extent a parasite is potentially metaparasitic 

 before it is introduced into fresh countries for the control of insect 

 pests.
