The above are all the figures, which I contributed to the Naturalist's 

 Library, and in most instances my name is added at the foot of each 

 plate in which my drawings were engraved, even where figures from 

 Cramer or other previous works were engraved on the same plates as 

 mine. Sometimes, however, my name is not added at the foot of a 

 plate which contained my drawings, as in the Volume of Exotic 

 Moths, Plate XXVIII. 



I am sorry to trouble you with all these technicalities, but I quitei 

 agree with you that it is better they should be given, to avoid othei 

 enquiries of a similar nature at a future time, when no such explana 

 tion could be giveu. J. O. Westwood. 



ON THE PROBABLE EXTINCTION OF LYC^NA AEION IN 

 ENGLAND. 



BY HERBKET W. MARSDEN. 



As Lyccena Arion has been a species of great interest to me fo 

 many years, and as I have paid much attention to its appearance an( b 

 distribution in this locality, a few notes from me may be of interes i 

 to the readers of the Eut. Mo. Maff.

It was on the 17th June, 1866, that I first saw the species alive' 

 when, in the course of a long Sunday ramble, I captured a singl'j 

 specimen in a narrow valley amongst the Cotswold Hills. A few day' '. 

 later I took another, high up on the open common ground, and mor ■ 

 than a mile from where the first was seen. 



From that year until this I have regularly visited the localitie 

 I discovered during 1867—70. Since 1869 I have kept no regula ' 

 diary, but only in 1870 did I find the insect really plentiful. 



The early part of June, 1867, was dark and cold, and I onl 

 secured some twelve or fifteen examples of L. Avion, usually not mor 

 than two or three specimens in any one day : the first being seen Jun 

 20th. These were all taken at what we may call the Stroud end c
