above 4 vertical, 7 and 8 long-stalked, 7 to termen, 1 1 from before middle, 
cell rather narrow, accessory cell absent. Hind wing broad, triangular- 
semiovate, slightly over 1, cilia J / 8 ; 2 from 3 / 4 , 3 and 4 connate, 5 — 6 
tolerably parallel, 5 from above middle, 7 curved downward at base, from

Genotype Polygiton pachypus spec, nov., male, female. 
Distinct by the thickened anterior legs. Differs from Hilarographa 
Meyrick also by separate veins 6 and 7 in the hind wing, from Heliostibes 
Zeller by shorter palpi and the origin of vein 2 in the fore wing; super- 
ficially is nearest to Anthophila Haworth, and possesses its facies, but 
differs in having subacute labial palpi, rough legs and quite differently
