and of the Eupelmidae, is accidentally printed as " a very short apical 

 spine." In page 3 Eutedouidae should be Entedonidae, and in page 60 

 Orctilia is a misprint for Oretilia. 



The affinity of the Encyrtidae to the Myinidae in structure, has 

 been already mentioned ; they are parasites of various insects ; many 

 of them are maintained in the bodies of Coccus-species. Some of the 

 Myinidae also feed on Cocci, and one species, Aphelinus tibialis, is 

 the devourer of Aphis Urticaria, on the bramble, where this Aphis is 

 more frequently the prey of an Allotria and much more often of an 

 Aphidius, all the victims being very few when compared to the 

 numbers which are soon afterwards removed by atmospheric agency.
