and about" twenty from Greenland before me, and' scarcely- 

 one specimen is like another in its variations." The article 

 is a long one (eight pages) ; to reproduce it would be out- 

 side the scope of this work ; I have merely secured some 

 slight indication of its drift. The variations described are 

 not specially nor definitely indicated as belonging to the 

 synonymic names quoted above. 



Since the above was written a specimen has been brought 

 under my notice which I believe to belong to the present 

 species, which yet is not included among the variations 

 specified, but is figured by Hiibner, Herrich-Schiiffer and 

 Hofmann as a distinct species under the name of Maillardi. 

 Its more important character of supposed distinction is the 

 comparatively greater length and narrowness of the fore 

 wings and their more pointed apex — but in this respect 

 G. exulis is notoriously unstable. The specimen to which I 

 refer was captured in August, 1896, by Mr. Percy M. Bright, 

 at sugar, with other forms of 0. exulis in the Island of 

 Unst, Shetland. Its ground colour is drab-brown abund- 

 antly marbled with umbreous and dusted with black, and its 

 only conspicuous marking is the reniform stigma, which is 

 distinctly edged with white in such a manner as to give 

 it a singular resemblance to Mamestra Ijrassiccc; a row of 

 white dots which is fairly distinct between the second and 

 subterminal lines in the the figures of Maillardi is only 

 faintly visible in this specimen, yet recognisable under 

 a lens ; it is moreover a little smaller than the figures 

 quoted, and than a female type from the Continent in my 

 possession. 



Staudinger, while giving it {Maillardi) rank as a separate 

 species in the genus Hadena in his list, adds a query as to 

 its being what he calls a " Darwinian " form of exulis, with 

 connecting variations. That it is a variety of this species I 

 feel no doubt. It is recorded from the Alps, the Pyrenees 

 and. the mountains of Norway.
