244 BEITISH BUTTERFLIES. 



rejected by them, as it was uninjured, and fed up on oak, pupating in 

 a few days, and producing an imago on July 16th, 1900. The larvae 

 are easy to rear, but are fearful cannibals (Lambillion). The canni- 

 balistic habit of fullfed larvae devouring those just a little advanced, 

 and, in the quiescent stage preceding pupation, has been frequently 

 noted. Jenkyns observes that, in June, 1881, a larva spun up 

 ready for pupation, was devoured by three others that were 

 being fed up with it, in spite of the fact that they had plenty 

 of fresh oak-leaves. Courtice also notes (Ent. Mo. Mag., ii., 

 p. 45) that the larvae of this species eat the newly-formed 

 pupae. On May 27th, 1865, he observed a larva busily eating a 

 pupa ; it had bitten off the anal end, and had cleared out the 

 contents, and, after being disturbed and liberated, it returned and 

 finished up the greater part of the pupal skin. The following 

 are the only dates of capture that we have noticed, almost all 

 of which refer to larvae having been beaten — June 4th, 1858, in 

 Maltby Wood, near Sheffield (Batty); May 25th-30th, 1865, at
