NOTES ON NEW AND RARE BRITISH LEPIDOPTERA. 125 



clue, we may look forward with confidence to the day when 

 Mydrilla will be better understood in this country. Its 

 habits, we are told, are very much like those of the Cava- 

 drince, 



Crymodes exulis, Lefebvre (assimilis). Three ex- 

 amples of this rarity were captured at sugar last summer 

 by Mr. N. Cooke, in Inverness-shire. 



Xylina furcifera, Hufnagel (1767) [better known as 

 X. conformh, S. V. 1776]. In the Ent. Mo. Mag. v. 278, 

 Mr. Allis acquaints us with the fact that he possesses an ex- 

 ample which was taken many years ago, near Halifax, in 

 the spring of the year. Mr. Buckler writes me that two 

 specimens have been captured at sugar in Monmouthshire 

 respectively by Mr. Philipson on the 2nd of October, and 

 by a friend of his a few days previously ; Mr. Hudd also 

 writes me that a couple of Welsh specimens have occurred, 

 but whether these refer to the above-named I cannot say. 

 Several specimens were originally recorded as having oc- 

 curred in S. Wales (vide Ent. Annual for 1862), so that 

 the species is by no means so rare as is generally believed. 

 We should expect that X. furcifera will some day turn up 

 at ivy and sallow bloom. 



Xylina Zinckenii, Treitschke. A third British speci- 

 men of this handsome Xylina^ captured in October, 1865, 

 was presented by its captor to the late Mr. Hopley, who thus 

 recorded it in the Ent. Mo. Mag. vol. vi. 252 :— " The follow- 

 ing must be amongst the earliest captures of this rarity. A 

 brother collector, a neighbour, lately brought me, as a present, 

 what he and his friends at the time considered a strange ex- 

 ample of Acronycta psi. * * * It appears that my 

 friend was out pupa-digging in the northern environs of
