from our own, (Staudinger and Wocke), I have added in brackets 

 the names common in England. 



i. Vanessa Atalanta L. {Pyrameis Atalanta L.) Frey Alp.; 

 Stdfs. Sil. Mont; H. Here. Mont.; Spr. Verbr. Lap. Ordinary 

 form ; in July. 



2. Vanessa CarduiL. {Pyrameis Cat -did L.) Mosch. Labr.J 

 Sch. Fen.; Frey Alp.; Stdfs. Sil. Mont.; Spr. Verbr. Lap. Ordinary 

 form, end of July, rare. 



3. Sphinx Convolvuli L. Frey Alp. ; Stdfs. Sil. Mont. ; 

 Spr. Verbr. ; Here. Mont. (Height uncertain.) Ordinary form, 

 August. 



* 4. Nemeophila Plantaginis L. Stgr. and Wk. Lap.; Sch. 

 Fen.; Frey Alp.; Stdfs. Sil. Mont.; H. Here. Mont. 



I saw only male examples of this species, which belonged to 

 the ordinary form ; some showed only a slight deviation in so far 

 as the ground-colour of the upper wings seemed to be a clear 

 whitish-yellow, and restricted the extent of the black marking, 

 whilst that of the under wing remained yellow. Dr. Staudinger 

 has remarked the same in Lapland ; and I have captured speci- 

 mens in the Upper Harz Mountains, in which the pale colour 

 reduced the black to a minimum. The varieties hospita Schiff. 

 and matronalis Fr. were not noticed in the Shetland Islands. 

 June. 



* 5. Hepialus Humuli L. and Aberr. Hethlandica. Stgr. 

 Wk. Norv. Alp.; Frey Alp.; Stdfs. Sil. Mont.; H. Here. Mont* 

 According to Mr. M'Arthur, the type form is prevalent in the Shet- 

 land Islands, whilst the male form with the female markings on 

 the upper wings {Hethlandica) appears in all transitions of ground- 

 colour, from the purest white male to the deep red-yellow or 

 brown-yellow of the upper wings, which usually appears in the 

 female insect of the type-form. I therefore refer Hethlandica as 

 an aberration to Humuli. The Entomologist gives a very interest- 

 ing series of figures of this Shetland form, I880, plate 3. 



I had here four examples of the Aberr. Hethlandica in charac- 

 teristic varieties for comparison ; and give a short description of 

 these four specimens, passing in order from that, which stands 

 nearest (in colour) to the female moth, on to that through which 

 the transition to the white form of the male is best shown. They 

 are as follows : — 



1. Ground-colour of the upper wings yellowish, the female
