Lasiocampa pini. According to some experiments of T. Goossens, this 
species can exist ten or twelve generations without interbreeding. An 
unfertilized ? at first deposited green and unfertile eggs, but, being pre- 
vented from depositing any more for eight days, at the end of that time 
she laid four lilac-coloured eggs, which produced larvae which lived till 
the second moult. In other species on which he has experimented, inter- 
breeding has generally destroyed the race almost immediately. Ann,
