Abstract

DESCRIPTION. Adults (Figs 1-214). Antennae setose ciliate in most genera, more rarely bipectinate or serrated. Proboscis present but rarely well developed and atrophied in several genera. Labial palpi generally short, approximately equalling diameter of eyes, mostly porrect, occasionally slightly ascending or drooping; frons in some genera with a rounded prominence. In keeping with the more or less involute resting posture characterizing the tribe, the forewings tend to be long and narrow, although they may also appear shorter and rounded, often uniform, sometimes unifasciate, the fasciae being rather diffuse and broad than sharply defined or punctate, or bearing paired vertical or, more rarely, horizontal discal spots. A transverse fascia across the median or postmedian part of the forewings occurs in both subtribes and may be ascribable to the ground plan of Lithosiini. A number of genera display secondary sexual modification of the wings; this may affect both fore- and hind wings. Androconia occur in several genera, usually on the forewings but occasionally also along the hind wing costa. Hind wings uniform, usually paler than forewings and mostly devoid of markings; leading edge occasionally with some dark suffusion. Underside also mostly unmarked, hind wings usually as upper side, underside of forewings with upper side markings, where present, showing through somewhat and interior not infrequently displaying dark suffusion.
