central fascia : cilia fuscescent : posterior wings whitish, with the hinder 

 margin fuscescent. 

 Said to appear in May, and again in September. 



Much less abundant than the last within the metropolitan district : 

 I have taken it in June near Highgate, and hav received it from 

 Devonshire. " Epping." — Air. Douhleday. " Dalmeny, near Edin-

Anterior wings luteous, with the base faintly darker, a central broad rufescent 

 fascia in the middle bordered with white, rounded on the hinder edge, and a 

 little attenuated towards the inner margin ; hinder margin clouded, with a 

 rufescent spot towards the apex, bordered by a whitish oblique streak arising 

 at the apex itself: posterior wings whitish. 



Caterpillar feeds on the poplar :— the imago appears towards the end of June. 



Always considerably smaller than the last, from which it also differs in colour, 

 and in the very decided diversity of form of the central fascia on the anterior 

 wings : whether it be the true Ge. Achatinata of Hiibncr I have no immediate 

 opportunity of judging *. 



Taken near Brockenhurst, in the New Forest. " Newby-cross 

 and Little Orton." — T. C. Hey sham, Esq.

* I may here take occasion to remark, that the references to Hiibner's beau- 

 tiful work, in my Catalogue, were made in 1818, from a copy kindly lent to me 

 by A. M'Leay, Esq. ; since when I have merely been able to procure occasional 

 glances at the copies of Messrs. Children and Haworth, and those mostly without 

 the insects for comparison ; consequently some few mistakes may have occurred 

 —the period of examination being so remote, and my experience in these matters 

 less confirmed.
