and 1862, p. 481—509, entitled, " Die Generationen und die "Winter- 

 formen der in Schleischen beobachteten Falter ;" and also Bossier's 

 " Verzeichniss der Scbmetterlinge des Herzogtbums Nassau," 1866 ; 

 and from tbem has extracted a list of the British species mentioned by 

 these writers, amongst those which they speak of as hybernating in the 

 egg ; Yon Prittwitz gives seven of the species mentioned in my list 

 No. 1, and the following eight in addition : — 



Argynnis Paphia, Thecla quercus, Thecla betulae, 



Chortobius Pamphilus, w-album, Liparis salicis. 



Lycaena Agestis ? pruni, 



Bossier gives 47 species mentioned in my first list, and 31 others 

 besides (some of which, however, I had put in my second list), viz. : — 



Thecla betulse, 

 w-album, 

 pruni, 

 quercus, 



Nola cucullatella, 

 strigula, 



Liparis salicis, 



Halia wavaria, 



Eupithecia tenuiata, 

 sobrinata, 



Eupithecia debiliata, 

 Thera juniperata, 



firmata, 

 Cidaria fulvata, 



pyraliata, 

 Diloba caeruleocephala, 

 Cymatophora diluta, 

 Nonagria geminipuncta, 



typhse, 

 Orthosia upsilon, 



Tethea retusa, 

 Euperia fulvago, 

 Dicycla oo, 

 Cosmia pyralina, 

 Polia nigrocincta, 

 Hadena protea, 

 Toxocampa craccse, 

 Catocala fraxini, 

 nupta, 

 promissa. 



rectangulata, 



A few of the species, however, given in these lists, seem to have 

 crept in by some mistake ; for instance, Mr. Buckler found when he 

 reared A. Paphia from the egg, that the larva hatched in August, hyber- 

 nated, and fed up in spring ; also in the case of 0. Pamphilus, eggs laid 

 ir> May became perfect insects by the following August ; perhaps, 

 however, Von Prittwitz may refer to the eggs laid by these August 

 butterflies. As to Lyccena Medon= Agestis (indicated with great doubt 

 by Von Prittwitz), Professor Zeller has elaborated its history with 

 great care (v. E. M. M., vol. iv, p. 74), and he there states that the larvae 

 hatch before August 31st, and hybernate in the same stage. 



Orthosia upsilon I know nothing about myself, but several of my 

 friends tell me it hatches in September, aud hybernates as a larva; 

 Polia nigrocincta has been the subject of notes by Messrs. H. Doubleday 

 and C. S. Gregson, at p. 90 and 116 of the current vol. of E. M. M., 

 and it appears that, whilst the latter gentleman gives it as a species 

 hybernating in the larva stage, Freyer and Milliere, as well as Bossier, 

 class it with those of which the eggs do not hatch till spring. 



I ought to have been able personally to vouch for Cidaria pyraliata 

 and fulvata, but they had escaped my recollection. — J. H.
