J.H. Durrant, del. 
Antennae biciliate ; basal joint with projecting shield of scales, without pecten. Labial Palpi evenly recurved 
to above vertex, smooth; median joint with appressed scales; terminal joint shorter than median. 
Maxillary Palpi well-developed. Haustellum scaled. Head with appressed scales, tending to project in 
front continuously with the clothing of the basal joint of the antennae. Thorax smooth. Forewings 
somewhat narrow at the base, widening outwardly, costa moderately straight, apex slightly depressed, 
termen oblique: newration 12 veins; 7-8 stalked, 7 to termen; 2-5 approximate, nearly equidistant ; 
1 basally furcate. Hindwings 1+; termen oblique, not sinuate, tornus evenly rounded: neuration 
8 veins; 6-7 stalked; 3-4 stalked ; 5 cubital, approximate to stalk of (3+4). Abdomen smooth.
