Wing of A. anthrax. part goes about from the apex of the subcostal vein somewhat out- wards to the base of the fork of the cubital vein and then very undulating or in a zigzag to the apex of the anal cell; the undulation is caused by the blackish colour stretching more or less out along the veins towards the hind margin; at the apex of the radial vein there is a small, isolated spot; at the posterior upper corner of the discal cell there is a somewhat pronounced clear spot. The costa is black haired at the base; squamulse with white hairs at the margin. Halteres black. Female. Agreeing with the male, only the frons slightly broader, and the inner eye-margins diverging just from the upper corner. Length 7—12 mm. A. anthrax is very rare in Denmark; we have only three speci- mens from earlier time, and without particular locality. Geographical distribution: — Europe down into Italy; towards the north to northernmost Scandinavia, and it seems most common in the north. 2. Hemipentlies Low. Species of medium size and black colour with black marked wings. The genus agrees in most respects with Argyramoeba. The head is globular, cut off behind and deeply excavated, about as broad as thorax. The eyes large, higher than broad, separated in both sexes, mostly so in the female; the posterior eye-margin is emarginate and from the middle of the emargination an inci
