Stigma present. Axillary lobe somewhat dev- eloped, not large. Alula not developed; alar squamula with long hairs forming a fan. So far as I am aware the developmental stages to this genus are not known; probably they live in the earth. The species of Hyhos are somewhat easily recognised by their slender, somewhat curved abdomen; they have a rather heavy flight. They occur in bushes and in herbage on the ground in woods on humid and somewhat shaded places; they are very often seen sitting just on the points of the leaves. All species occur late in summer and autumn, my earliest date is '«, and this is exceptionally early, and I have taken them to the end of September. Tiiey are evidently carnivorous; I have often taken them with prey, generally small Diptera; the prey of the single species is recorded below. Of the genus 9 species are recorded from the palsearctic region, but as will be seen below I think there are in reality only 4, three of which belong to Europe, all three also occurring in Denmark.
