I AM surprised to find that in an elaborate work like Treit- 

 schke's Schmetterlinge von Europa, no notice is taken that I 

 can see either of Tinea Scissella or T, Festaliella Hlib. I 

 stated some years since, when I characterized the genus Chry- 

 socorys in the Entomological Magazine, that I was veiy 

 doubtful if the insect before us were the T. Scissella of Hiib. 

 pi. 39. fig. 270, the wings being of a different shape, and I still 

 entertain the same opinion; it is however unnecessary to super- 

 sede Mr. Haworth's name, since if they be different insects, 

 they do not belong to one and the same genus. On the con- 

 trary, I have little doubt that Hiibner's Tinea Festaliella, pi. 67. 

 fig. 449. is a variety only of our insect or at least of the same 

 genus, which has induced me to give outlines of the larva and 

 pupa of that species from his work, in order that their singular 

 figures may be better known. It is clear from them that this 

 Moth is closely allied to the Pterophori (pi. 161.), and it is 

 very interesting to mark the similarity of the larva and pupa 

 to those of the Papihonidae. The pupa is inclosed in a cocoou 

 of beautiful lacework which does not conceal it, and in this 

 respect it resembles CeroUoma Hesperidella (fol. 420). 



This elegantly formed little Moth is found during the spring 

 and summer months ; I have met with it as early as the middle 

 of April flying amongst the plants on hedge banks near Glan- 

 ville's Wootton, the middle of May at Rougham in Suffolk, 

 the middle of June amongst the broom near Coomb Wood, 

 and the end of the same month on brambles in the Isle of 

 Portland. 



The Plant is Thlaspi peyfoliatum, Perfoliate Shepherd's 

 Purse, from the neighbourhood of Slaughter in Gloucester- 

 shire, a locality pointed out to me last June by E. F. Witts, Esq.
