TitleOn some Western European Aphids
JournalZoologische Mededelingen
Abstract1. The genus Atheroides Haliday Of this genus 3 Western European species are known : A. serrulatus Hal. (syn. festucae Mordv.?), A. hirtellus Hal. (syn. A. junci Laing) and A. brevicornis Laing. a) A. serrulatus Hal. is quite common. It lives on Poa annua often, but prefers species of grass with narrow, folded leaves, such as Festuca ovina, F. rubra, Nardus etc. b) A. hirtellus Hal. is not rare on Aira caespitosa. It seems to live on that plant only. c) A. brevicornis Laing is extremely common along the muddy seashores of the Netherlands. It prefers Festuca thalassica and F. distans, the two typical species of grass growing there 2). The alatae have not yet been described and therefore I add a short description. The apterae have been described excellently by Laing, but I redescribe them for comparison.
