The end of the body has no cremaster,but, what is unique, a hook arising from each vestigialanal leg. Finally, it will bereaddy seen thatfrom an examination?of the pupa- the views of Speyer, of Chapman, and of Comstock, as to the position of the I\sychidiBis fully confirmed, while I should go a little further and place them still nearer the Hepialida?.They are, however, still more modified than this last-named group, since the females are wingless.
