Wings with the subcostal vein short: the cubital vein unforked, thus one cubital cell; the discal vein forked and thus four posterior cells; no discal cell; the lower branch of the postical vein going straightly downwards; the second basal cell a little shorter than the first, the anal cell as long as the second basal cell; anal vein not reaching the margin. No stigma. Axillary lobe not developed. No alula, the wing-margin here only short fringed. Alar squamula very narrow, with some long hairs at the margin. The developmenta

Wings with the subcostal vein short: the cubital vein unforked, thus one cubital cell; the discal vein forked and thus four posterior cells; no discal cell; the lower branch of the postical vein going straightly downwards; the second basal cell a little shorter than the first, the anal cell as long as the second basal cell; anal vein not reaching the margin. No stigma. Axillary lobe not developed. No alula, the wing-margin here only short fringed. Alar squamula very narrow, with some long hairs at the margin. The developmental stages are not known. The small and delicate species occurs especially in woods on shaded and humid places. The genus comprises only one species, also occurring in Denmark. 1 Girschner says (111. Zeitschr. fiir Entoni. 1897, 557) that of the Hemerodromiinae only CUnocera has hairs on the metapleura, but both the present and the fol- lowing genus have distinct metapleural bristles.
