ANESYCHIA, Steph. 
Hind wings rather broadly oblong with short cilia. The subcostal 
vein is simple. The discoidal cell is closed by a transverse discal vein 
which gives rise to two branches. The median vein is 3-branched, the 
two upper branches, arising from a short, common stalk. The subme¬ 
dian and internal veins distinct. 
Pore wings elongate ovate. The subcostal vein subdivides into four 
branches j the first is given olf near the middle of the wing and the 
apical branch furcate. * The discal vein has two branches and the me¬ 
dian is 3-branched, all the branches being aggregated at its posterioi- 
end. The submedian furcate at the base. 
Head smooth. Ocelli none. Antennae of the males with the joints 
rather dentate and pubescent-ciliated. Labial palpi smooth, cylindric, 
moderately long, exceeding the vertex somewhat,- reflexed with the 
third joint pointed; middle joint longer than the terminal joint. No 
maxillary palpi. Tongue of moderate length, clothed with scales to¬ 
wards the base.
