EXPERIMENTS UPON ACRJEA ENCEDON. 



397 



The results of breeding the Wild Larvae, the Companies, and Families 1-3 have been 

 recorded in Proc. Ent. Soc. Lond. 1911, pp. liv-lvi, before the appearance of 

 Eltringham's monograph, containing a thorough account of all the forms of ^. encedon. 

 The darker forms found and bred at Oni, named ejicedon in the 1911 publication, are 

 now recognised as infuscata, and a few as commixtd.

The proportions, suggesting heterozygote 

 lycia for both parents, are more pro- 

 bably due to a special batch of ova.
