Stigma present. The axillary lobe well devel- oped, Alula not present, the margin here haired. Alar squamula small, fringed at the margin. The developmental stages of the genus are not known. The species of Euthyneura occur in woods on more or less hu- mid piaces. Zetterstedt records the various species from the leaves and flowers of Betula, Salix and Sorbus. The species are for a great part boreal. Of the nine recorded European species four are only known from Scandinavia, and in all eight occur in Scandinavia to ils northern parts, only one species is only known from middle Europe. The species are all rare, and become especially rare towards the South; thus Strobl notes, that of the four species known froniAustria there has only been taken one female of each. Of the genus 9 species are known from the palæarctic region, two have hitherto been found in Denmark.
