It goes without saying that the full life of the intern:il-feeding parasites of this group is very difficult and impossible to follow so long as they are within the body ol the host insect. In our earlier consideration of the Proctotrypoidea we have given some gent-nl remarks upon the development of all internal-feeding parasitic Hymenopterous larvx, and those re- marks will apply in general to the tlies. are some of them, however, whose larvx do not feed intjrnallv. These .irc especially those which are upon the of\,all-making insects.
