(Fig. 8.) Wings non-petiolate, densely reticulated, including, in some genera, the basal space (but this entire in the majority), more or less broadened, the greatest breadth being near the middle of the wings. Nodus from one- third to half-way along the costa; arculus always normal and situated much nearer base of wing than nodus. Antenodal complex complete as in the Epallagidae; Rs and MA arising from arculus at or below its centre, or, in the case of the Hetaerininae, from its lower part close to CuP. Rii + iii arched as in the Epallagidae and usually fused for a short space with Ri. Discoidal cell either an elongate rectangle, very narrow, simply crossed or densely reticulated, or else an irregular quadrilateral with convex anterior side, as in the Hetaerininae. Supplementary veins very numerous, straight or more or less strongly curved. The anal vein, IA, which in all previous families forms part of the posterior border of the wing in its basal portion, is, in this family, for the first time, entirely within the wing, and the whole posterior border a simple vein; distally, after the level of the discoidal cell, IA turns obliquely posteriorwards and is then either strongly curved sig- moidally or more or less complexly branched owing to a linking up of some of the numerous supplementary veins developed posterior to it. Usually many additional cross-veins in the cubital space, so that the anal tracheal crossing, Ate (= Ac Tillyard) is usually obscured (it is isolated and distinct in Vestalis amoena). Pterostigma variable, often reduced or entirely absent, especially in the males (in the females, it is usually in a state of atrophy as evidenced by a number of new or additional postnodal veinlets which traverse it; this is usually alluded to as a "false or pseudo&quo
