as long (supposing that the insect came from Shetland, the 

 nearest land) as that which Mr Clarke's notes indicate. I 

 have never seen any Ehopaloceran myself in the Faroes, 

 though I have been there in all the summer months. 



Hansen {loc. cit.) records the following moths : — Epiahis 

 hiomuli*, Agrotes promiha^, Charceas graminis^, Mamesira 

 dentina, Hadena sommeri, Hadena exults, Hadena monoglypha, 

 Cidaria lyiunitata, Cidaria designccta*, Cidaria adcequata, 

 Cidaria albulata*, Scoparia amhiqualis, Tinea fuscipunctella, 

 Tinea sp. 



Those marked with an asterisk also occur in my collection. 

 I am able to add the following records : — Plusia ganima, 

 Melanippe sp., and Osseana pratana. 



Possibly my Melanipjje sp. is one of Hansen's species of 

 Cidaria, as this author gives the latter genus a very wide 

 application; but it appears to differ slightly from any species 

 of this group hitherto described, and also from authentically 

 named specimens in the Hope Collection at Oxford. It may 

 be a form of M. montanata. 



Hepialus humnli. 



Epialus humuli, Hansen, loc. cit. 



This species is either very local or has a restricted season 

 in the Faroes. I have only met with it on one occasion 

 myself. This was at Klagsvig, in the north of the group, on 

 the evening of July 19th, 1900. On that evening, between 

 the hours of 8 and 10 p.m., I took 11 males and 4 females.^ 

 The individuals of both sexes varied considerably in size. 

 Of the males, 4 were silvery white, the remainder approxi- 

 mating to the female more or less closely in coloration. No 

 specimen, however, was quite so dark as any in a large series 

 of the variety hethlandica from Shetland preserved in the 

 Hope Department of the University Museum at Oxford. 



It is unfortunate, however, that we have no exact in- 

 formation regarding the relative frequency of occurrence of 

 the two varieties {i.e., tyyica and hethlandica) in Shetland. 

 Collectors naturally choose out the most abnormal specimens, 

 and probably the proportion of the typical variety is very
