Maxilhe longer than usual and very well develoi)ed, forniiug several coils. Thorax notcrested. Fore wings rather less than one-half as long as broad; costa nearly straight or slightlyconvex; apex somewhat rounded or pointed or (in hydronieli) squarish, (in nnicolor abruptly bent),but usually somewhat produced; outer edge long, oblique, convex (in vnicolor sharply bent onfirst cubital venule, III;). Hind wings shorter and more rounded at the apex than in any othergenus of the family, outer edge shorter, more regularly rounded than usual; costal and inner edgeof nearly the same length.

Venation much as in Schizura, but quite variable; usually a long narrow subcostal cell,though it is sometimes open in individuals of the same species; the third subcostal venule is veryshort, and the cell between it and the fourth is minute; in the siiperba and hydromeli group thesubcostal venules tend to be bent up at their end toward the costa, and so in ^fc/cand hiundata,but usually they are diverted more toward the apex, and then more parallel with the costa; thediscal venules vary in length and direction; the anterior one is usually short and divertedobliquely inward to where it meets the sixth venule; the hinder discal venule either forms aregular curvilinear line, or is broken into two portions forming an angle witli the apex, pointinginward, from which the median di
