Two lepidoptera, Orthonama obstipata (Fabricius, 1794) (Geo.) and Ipimorpha contusa (Freyer, 1849) (Noc.) new to Norway, and faunistical comments on two rare noctuids. GEIR E.E. S0LI S01i, G.E.E. 1988. Two lepidoptera, Orthonama obstipata (Fabricius, 1794) (Geo.) and Ipimorpha contusa (Freyer, 1849) (Noc.) new to Norway, and faunistical com­ ments on two rare noctuids. Fauna norv. Ser. B. 35, 49-52. One female of the migrating Orthonama obstipata (Fabricius, 1794) was recorded from Gravastranda, Porsgrunn. According to the weather situation in the North Atlantic at the time the specimen was caught, it is stated that the specimen most probably has reached Norway from The British Isles. One male and one female ofIpimorpha contusa (Freyer, 1849) were recorded from Dammane, Porsgrunn. The species has a very restricted distribution; in Fennoscandia previously only known from the southernmost parts of Finland. Both species were taken in 1983, and recorded for the first time in Norway. Specimens of Cryphia domestica (Hufnagel, 1766) have been recorded from several localities in the surroundings of Porsgrunn. In Norway the species has not been recorded outside this area, where it seems to have a stable population. Apamea scolopacina (Esper, 1788) is recorded from Porsgrunn. The species has previously only been taken once in Norway. Geir E.E. S01i, Zoological Museum, University of Bergen, Museplass 3, N-5007 Ber­ gen, Norway.

In Europe the species is native in the (See Ellefsen 1984). The localities were: Mediterranean area only, where it has several Gravstranda (UTM: 32VNL37I500; EIS 18) generations during the season (Hoffmeyer and Dammane (UTM: 32VNL391469; EIS 1966) and feeds on a variety of herbaceous 11) (Fig. 1). - The former thermophilous plants (Vilhelmsen 1980). 0. obstipata is, deciduous forest, the latter basiphilous pine however, a well known immigrant in most forest.

In Denmark more than 80 specimens two other rare noctuids, Cryphia domestiea have been recorded, and the species is taken (Hufnagel, 1766) and Apamea seolopacina in all provinces (Schnack 1985). In North (Esper, 1788) were caught. Europe most specimens arrive in the autumn, but specimens have also been caught in May, July and August (Skou 1984).

Ser. B. 35: 49-52. 49 It seems thus reasonable that the norwe­ gian specimen of O. obstipata arrived from The British Isles. In The British Isles no less than 56 specimens of O. obstipata were re­ corded during 1983, that means the species was more frequent than most years (Brether­ ton, pers.com.). The british specimens were recorded from 4 June to 13 November, and some of those taken in October and Novem­ PORSGRUNN ber may, according to R.F. Bretherton (pers. corn.), have been bred in England from early arrivals. Ipimorpha contusa (Freyer, 1849) One male and one female were caught at Dammane during the period 26-31 July. I. contusa has a highly disjunct distrib­ ution: In Asia it is recorded from the Chen­ tejn-mountains in Mongolia, and from the Amur and Ussuri area in the USSR; In Eu­ rope it is recorded in the surroundings of Thiiringen and Sachsen, in East Prussia and in the southeastern parts of Finland (Hanski & Kaisila 1971). In Finland the first specimen ofI. contusa, o a male, was taken in Vehkalahti, Etelii-Hiime on 23 August 1965. However, this specimen was not identified until a second specimen, a female, was caught in a light trap in Virolahti, Fig. 1.
