Pro- boscis more than half as long as the body, directed forwards and more or less downwards; labrum as long as the basal part of labium, pointed at the apex; the maxillae are long, chitinous threads, and likewise hypopharynx which is slightly broader towards the base; the maxillary palpi are small, one-jointed, beset with hairs; hypopharynx and maxillae a little longer than labrum, hypopharynx the longest; labium long and thin, strongly chitinised; the basal part is long, twice as long as the labella; these latter are narrow, not broader than the basal part, chitinised; they are indistinctly two-jointed, and they are able to be spread out and recurved. In rest the oral cone is infolded, but the proboscis protrudes. Thorax short, almost quadrate; postalar and scutellar marginal bristles may sometimes be visible in the clothing; metapleura with long hairs. Abdomen short, pointed behind, con- sisting of seven not transformed segments. The male genitalia re- semble those in Argyramoeha, but they are asymmetrically turned; they consist of an eighth, small but normally shaped segment, at the apex of this, above there is a somewhat triangular plate, divided longitud- inally by a suture; its two halves are somewhat divergent at the end, and each has a two-pointed apex, the outer point being the longest; at the ventral side there is a somewhat semiannular plate with two small lamellae at the apex. The female genitalia also resemble those in Argyramoeha and Anthrax and there are the same two combs of spines, but they are quite withdrawn, and the opening leading to them is closed by dense, converging hairs. Legs with shorter or longer, strong bristles on the ventral side of the posterior femora, or only on the hind femora, and on the tibiae, those on the front tibiae small; all tibiae with apical spurs, on the fro
