Slender species. Eyes large, extending almost to the anterior margin of the clypeus, converging to the clypeus; facial quadrangle narrow, much narrower than the length of the eyes; clypeus truncate, or nearly; palpi large; supraclypeal suture present, straight; frontal carina strong; antennae inserted near the middle of face; ocelli in a curved lme, the lateral ones tangent to the supraorbital line; posterior orbits very narrow; antennae bifurcate in male; female unknown; tarsal clawssimple; hind basitarsus longer than the following joints; fore wings: radial cell not appen- diculate; four cubital cells, the basal three small, the second and third each receiv- ing a recurrent vein near the base; basal vein remote from the origin of the cubitus; anal cell petiolate; transverse median received before the middle of the cell; hind wings: radial cell open; two discal cells; anal cell about the same length as the petiole.
Type.-Manaos nigfinotatus sp. nov.

Labrum narrowly arcuately ernarginate; supraclypeal area convex; antenna] furrows present, broad, shallow, nearly complete; vcellar basin oval in outline, more sharply defined near ocellus; postocellar furrow present, angulate from anterior ocellus; postocellar area not defined laterally; postocellar line subequal to the ocellocular line; hypopygium short, broadly rounded apically; stigma broad at base, tapering to a pointed apex; third cubital cell nearly quadrate. Testaceous; head above antennae, meso- and meto-notum, tibiee (except beneath), tarsi, apical three tergites and apical sternite black; clypeus, labrum, mandibles (except piceous apices) and base of venter pallid.
