patch covering the base of the mesepimeral 
hair tuft and approximately V-shaped), the 
scale patches not forming sharply defined 
lateral bands. Legs: Femoral knee-spots pres-

simple. Wings: Dark-scaled, a small basal spot 
of silver scales on the costa. Abdomen: Ab- 
dominal tergites with narrow (sometimes 
incomplete) basal bands which widen into 
spots sublaterally, detached oblique lateral 
spots also present. Sternites with basal white 
bands. Terminalia: Basistyle with prominent,
