4 THE ENTOMOLOGIST. 



Melanippe montanata. — Those taken are of the normal colour, 

 except one very light variety; but none approach the variety 

 Shetlandica. 



Cidaria russata. — This variable insect, which is so uniform in 

 colour in the Hebrides, is in the Orkneys very variable ; two 

 specimens present the extreme aberration of a yellow ground 

 colour to the upper wings, with black lines. 



Cidaria immanata. — The Orcadian closely approach in colour 

 to the Shetlandic. 



It may be here remarked that in the Shetlands it appears 

 C. immanata is found, and not the closely-allied C. russata ; 

 in the Hebrides the reverse is the case, but in the Orkneys both 

 species are found ; indeed all the evidence shows that the latter 

 islands are barely insular in their Lepidoptera. 



Cidaria testata. — The specimens are of a dark purplish lead- 

 colour in their markings, and, like those from Shetland, are 

 devoid of yellow. I believe that this dark form of the insect may 

 be often found farther south, as I find one in my collection 

 labelled as taken by myself in the New Forest. 



Trijihcena orbona. — Only one specimen taken, and that of the 

 form known as Curtisii. 



Noctua festiva, N. Dahlii, and N. ruhi. — These three species, 

 taken in the Orkneys, resemble each other very closely, and 

 it requires a careful examination to separate them ; the pre- 

 vailing colour in each species is ruddy brown. The same remark 

 applies, but in a less degree, to N. xanthographa. 



Epunda lutidenta var. Luneburgensis. — This is a very inte- 

 resting capture ; several specimens taken agree well with the 

 description given by Staudinger in his ' Catalogue of European 

 Lepidoptera,' No. 1341, p. 95. He writes as follows : — " Nigricans, 

 fasciis distinctis albis." The habitat given is South-western 

 Germany ; ? Pyrenees. 



The subject of the entomological fauna of the more remote 

 British Isles is a new field of investigation, and promises to yield 

 good results to those who engage in it. At present we know, and 

 probably only partially, the Lepidoptera found in one of the 

 Shetlands, Mainland ; one of the Orkneys, Hoy ; one of the Outer 

 Hebrides, Lewis ; and very little of any other islands of the three 

 groups. 



There can be no doubt that the Fseroe Isles, although
