NOTES ON NEW AND RARE BRITISH LEPIDOPTERA. 121 



Surrey; two fine examples of Dicrorampha flavidorsana 

 at Alphington, near Exeter ; Sedya Servillana and Eupce^ 

 cilia curvistrigana at Haslemere ; Bactra uliginosana at 

 Wicken Fen ; Sericoris euphorhiana, which, since the 

 clearing up of its natural history by Professor Zeller in the 

 pages of the Magazine, bids fair to become a common 

 insect; and Eupoecilia anthemidana in Norfolk, only there 

 appears to be some doubt whether this be not a species dis- 

 tinct from anthemidana. 



A good many varieties and aberrations have been recorded 

 in 1868, among which may be mentioned a Manx race 

 (dwarfed) of Vanessa iirticce and Anthocera JilipendulcB, 

 two Ephyra omicronaj-ia^ minus the omicron ; white and 

 yellow-banded Sesia cidiciformis ; a very extraordinary Se- 

 tina irrorella, with a strongly-marked subterminal fascia ; 

 a white Cr. Phloeaa ; a cream-coloured Ai^ctia vHUca ; a 

 Caja, with chocolate fore- and black hind- wings ; herma- 

 phrodite Bomhyx quercus and I£ij)parchia Semelefj Lyccena 

 Alexis, &c. &c. 



Re Colias Hyale. 

 At page 175 of the Ent. Mo. Mag. Mr. Barrett endea- 

 vours to account for the occasional abundance of C. Hyale 

 by other causes than migration. He shows pretty conclu- 

 sively, by contrasting the relative condition of specimens 

 with their respective localities and dates of occurrence, that 

 those taken inland cannot very well be stragglers from the 

 coast. He accounts for the perpetuation of the species, in 

 spite of changes of crops, &c., by the instinct of the ? in 

 distributing her eggs widely and sparingly, and he shows, 

 too, that the insect actually emerges, and consequently feeds 

 up, in this country, a fact which is fortified by a com- 

 parison with the natural history of its near ally, C. Edusa;
