Posterior- tibiae each with two short spurs; no combs. (Jlaws simple. Winys well devel()])ed; venation as in Sclara : no macrotrichia on membrane. d'lie reduction in the number of antennal seyments neeessitates the ei'ection of a new yeniis for the species described below, which otherwise might be placed in ^cythro pock rod or Plasfoscuira. No such reduction has previously been found in the iSciarinae. It is true that Schiner's Colombian genus Pseudosciara is also devscribed as having 2-i-l<> segments in the antennae; but this differs in many respects from the ])resent genus, and jirobably does not belong to the same subfamily. K). Dodecasciara debibs, sp. n. $. Head blackish, antennae and pal])i dark. Eye-bridges narrow, only 1-2 facets wide, ocelli not far removed from them. Antennae short, flagellar segments scarcely as long as broad, pubescence short, no distinct necks. T/torox small but rather strongly arched above, brown ; hairs inconspicuous. Abdomen long, light brown, ovipositor darker. Tergites 1-7 all well-developed, broader than long. Cerci rather elongate oval. Legs short, brownish-ochreous. Femora, tibiae and tarsi all about equal in length. Spurs shorter than the tibial diameter. ]Vings rather narrow, nearly clear, veins not very dark.
