Genus CYATHOCERA. Ps 
Head subovate, as wide as the thorax, the ocelli placed 
in a slight curve on the vertex; the maxillary palpi six- 
jointed, the basal joint stoutest, the joints gradually de- 
creasing in width to the apical one, and also in length, 
but only slightly so; the labium short and lanceolate, the 
paraglosse two-thirds of the length of the labium; the 
mandibles bidentate in the female, the teeth blunt ; in the 
male they are edentate and acute at their apex. The 
wings with one oblong marginal cell, rounded at its apex, 
three submarginal cells, the second one-third longer than 
the first, receiving the two recurrent nervures, each at 
about one-fourth of the length of the cell, the tegule 
enlarged in both sexes; thorax ovate, the posterior legs 
have the femora fringed with pubescence beneath, and the 
tibize and basal joint of the tarsi furnished with a dense 
scopa; in the male the posterior legs have the femora 
enlarged and the tibiz curved, with the apex dilated.
