Mr. J. E. Fletcher has a note in the March No. of Newman's Entomologist, on “Controlling Sex in Lepicloptera” He says :“ During last summer, I had a few larvæ of EXapate congelatella feeding on privet; as I was greatly occupied with other things, they were neglected ; the supply of food was very irregularly given and short in quantity, yet the moths produced from them consisted of four males, full sized, and eleven females, some of these latter being much below the average of the species in size.”
