but the palpi are different, shorter and stouter than usual, with 

 rather peculiar scaling. Imago with forewings elongate.

Antennas |, in ^ serrulate, simple, basal joint moderately 

 elongate, without pecten. Labial palpi long, recurved, second 

 joint with scales somewhat rough beneath, terminal joint shorter, 

 acute. Forewings : 2 and 3 separate, 6 absent, 7 and 8 stalked, 

 7 to costa. Hindwings 1, trapezoidal, apex pointed, termen 

 sinuate, cilia 2; 3 and 4 connate, 5 somewhat approximated to 

 4, 6 and 7 approximated. 



Although differing in several important points of structure, the 

 two species which form this and the next genus are so similar in 

 other respects that they must be supposed to have near collateral 

 relationship together, their ultimate origin being Protolechia. 

 Imago with forewings elongate, tolerably pointed.
