Gen. Char.: Head transverse, scarcely so wide as the thorax, flat; ocelli in an open triangle on the vertex; face flat; clypeus transverse, margined; labrum transverse, slightly rounded in front; mandibles bidentate; cibarial apparatus moderately long; tongue lanceolate, fringed with delicate hair; paraglossæ about one-third the length of the tongue, abruptly terminated, lacerate and setose at the extremity; labial palpi rather longer than the paraglossæ, the basal joint considerably the longest, all the joints subclavate and diminishing both in robustness and length to the apex; labrum half the length of the entire apparatus, its inosculation acutely triangular; maxillæ subhastate, as long as the tongue; maxillary palpi six-jointed, less than half the length of the maxillæ, the joints short, subclavate and decreasing gradually from the base to the apex. Thorax densely pubescent, obscuring its divisions; metathorax truncated; wings with three submarginal cells, and a fourth slightly commenced, the second subquadrate and receiving the first recurrent nervure in its centre, the second recurrent nervure issuing from beyond the centre of the third submarginal cell; legs all pilose, especially the posterior pair, which have hair beneath the coxæ and trochanters, above only on their femoræ, but surrounding the tibiæ, and as dense externally upon their plantæ; claws distinctly bifid. Abdomen ovate, truncated at the base, the segments banded at their apex, with decumbent down, which becomes densely and widely setose on the fifth segment, the terminal segment having a central triangular glabrous plate, carinated down the centre, and very rigidly setose laterally.
The MALE scarcely differs, except in having the antennæ less distinctly geniculated, the flagellum taking a sweeping curve, the face and clypeus much more pubescent, but the legs sexually less so; the sexes are much alike.
