THE YOUNG NATURALIST. 



cavated and occupied successively until four or five sack-like discoloured and 

 contorted leaves can be seen, with one or two young terminal leaves above 

 them. The whole of the four or five excavated leaves are slightly joined to- 

 gether, so that the larva, which never leaves its home, can live and feed con- 

 tinuously from the moment of entry to the pupa state, free from fear of bad 

 weather. The pupa lays in the upper leaf -sack, and on the insect emerging 

 is porrected two-thirds out of its recent puparium. The larva is stout ; head, 

 brown ; body, cinereous ; feeds in June. Pupa rather light coloured ; imago 

 end of June or July. This is one of the most interesting discoveries of 1885, 

 so far as I know the work done this year. The species was taken rather 

 freely in the Rannoch district many years ago by a man I sent up there, but 

 he failed to find its larva, though in searching for it he found and sent to me 

 many larva of Euchromia arbutana. I had requested him to send me the 

 tied-up terminal shoots of the A. uva-ursi, and he did so, and from them I 

 bred plenty of E. arbutana, but it now evident he cared nothing for the 

 bladdered leaves on the terminal shoots, and so left them as dipterous. —

Anarta IVJyrtilli with two Parasites.-— Mr. P. N. Pierce has very 

 kindly sent me some parasites from Anarta myrtilli larva, and has asked the 

 question " Is it a common occurrence to have two different pupa from the 

 same larva ? Reply. — It is a very rare occurrence to have two direct para- 

 sites from one larva, it this instance one cocoon is an ichneumon and I believe 

 a Paniscus, the other a dipteron, probably an Exoristes. It must be under- 

 stood that we often get two species of ichneumon from very similar pupae, 

 for instance you may get half-a-dozen pupoe from one larva, the pupse made 

 by the same species, therefore would be alike ; but in breeding we often find 

 that three may be of one species and three another, one species being a para- 

 site on the other. I remember once having six parasites from Grossulariata, 

 the pupse were those of Casinaria vidua, but I only bred one vidua, the 

 others contained two species of hyper parasites, Mesochorus fulgurans and 

 olerum. — G. C. Bignell, P.E.S., Stonehouse. 



Notes from Derby. — In company with a friend we set out for a ramble 

 in search for larvse, we walked from Derby to Little Eaton, a distance of four 

 miles along the canal, but did not find anything of note but a species of 

 Donicia, on the weeds in the canal. When we arrived at our collecting 

 ground my friend had the first find in the larvse of Acronycta rumicis, and 

 we soon found about a score between us ; a little higher up the lane we 

 found the larvse of the Buff- tip (Pygcara bucep/tala) on some oak trees from 

 which they had cleared the leaves from several large branches. Prom the
