Njarðvík, Norður-Múlasýsla, E-Iceland. In this last men-
tioned locality the farmer thought that he had first no-
ticed the species in 1935. About this time (1940) the spe-
cies had reached Akranes, W-Iceland; Borgarnes, Mýra-
sýsla, W-Iceland, Grindavík, Gullbringusýsla, SW-Iceland,
and Hvolshreppur, Rangárvallasýsla, S-Iceland, and it had
also been found at some farms in Fnjóskadalur and Ljósa-
vatnsskarð, Suður-Þingeyjarsýsla, N-Iceland. In 1943 it
was recorded from Hemra and Vík í Mýrdalur, Vestur-
Skaftafellssýsla, SE-Iceland. In 1944 Ingimar Óskarsson
found the species at Kópasker, Norður-Þingeyjarsýsla,
NE-Iceland, and Steindór Steindórsson recorded it from
Króksfjarðarnes, Barðastrandarsýsla, NW-Iceland. In 1945
it had reached Laugar in Sælingsdalur, Dalasýsla, W-Ice-
land. In the years 1954—1956 I recorded the species from
Sauðlauksdalur, Barðastrandarsýsla, NW-Iceland; Hnífs-
dalur and Isafjörður (the city), Isafjarðarsýsla, NW-Ice-
land; Hellnar and Stapi, Snæfellsnessýsla, W-Iceland;
