104 AN ANNOTATED LIST OF LEPIDOPTERA KNOWN FROM THE FAROE ISLANDS Hoyvík, a male and a female 2-9.VIII.1993. Kunoy, at'emale 10-28.VIII.1996. Vág: Miðvágur, amale 6-31.VII. 1997 (NM). (50) Xestia c-nigrum.Vagrant. One light trap record. Kunoy, one 6-17.VIII.1997 (NM). (51) Xestia alpicola. The mountainous Faroe popula- tion has been described as ssp.atlantica (Kaaber, 1996). (52) Anaplectoides prasina.Vagrant. An offshore record was made in 1996 where a male specimen was found on August 10 on a ship five kilometers north of Viðoy (Paco Bustamante leg., FN ). See Kaaber(1997). (53) Arctia caía.Vagrant. One light trap record. Sud:Trongisvágur a male 24.VII- 6.VIII.1995 (NM). (54) Antichloris spec. Casual introduction. A dead pupa was found in its web among imported bananas in a supermarket in Tórshavn in 1993 by Mr.Jens- Kjeld Jensen, Nólsoy and shown to SK in 1994. A final determination has not yet been made. Discussion The present checklist enumerates 108 species, an increase of 51 species compared with the former checklist from 1970. The three butterfly species in the list without figures represent records based solely on observations. Due- to the lack of voucher material the reliability of these records can be questioned. With regard to the observa- tions of Colias crocea and Pieris brassicae, misidentification has been considered neg- ligible (Kaaber et al, 1994). In the case of the third species, Nymphalis antiopa, this risk is much more significant. Thus the two related butterflies Vanessa io and Inachis io can easily be confused with antiopa due to their swift and powerful flight and dark ap- pearance, especially when viewed at some distance. Furthermore it is suggestive, that antiopa neither in Shetland nor on Iceland, contrary to the Faroe sightings, has been recorded in May or June, but only in Au- gust-September. In Shetland the species has been recorded on six occasions, in every case with a close relationship with a concurrent migration into Southern Eng- land (Gear, 1995). The three records from Iceland have all been connected with tim- ber importation from Europe during late summer (Olafsson and Bjørnsson, 1997). The Faroe sightings may, however, be in- terpreted as casual vagrants from Western Norway. At the present stage of knowledge Nymphalis antiopa is placed on the check- list with reservation, and it is to be hoped that its presence there can be safely con- firmed in future. Nine lepidoptera species which earlier have been recorded from the Faroe Islands have not turned up since 1970, despite the efforts which have been made during the study to rediscover them. Two of these species, Tinea pallescentella and Elachista albidella are probably overlooked due to secretive habits and inconspicuous appear- ance. Another three, Coleophora serratel- la, Acleris notana and Chloroclysta citrata, have seemingly no resident populations on the Faroes at this time. The well-known and conspicuous migrant moth Acherontia at- ropos has always been a great rarity on the Faroes, where it wás last observed about 1953 (Wolff, 1970).The three last species in this group, Paralipsa gularis, Anagasta kuehniella and Caradrina clavipalpis, have all been introduced with victuals and may therefore turn up on the Faroes in future. Among the 56 species, listed under the category R, 48 have stable Faroe popula- tions. Further eight species, namely Tinea pallescentella, Coleophora versurella and
