Type, Hyale, Linnaeus (European). 
Antennse short, with a large but gradually-formed club. Palpi long, compressed, 
scaly, and somewhat bristly, the terminal joint short. Tarsi without appendages. 
Wings rather short and broad; the Hindwings rounded, the Forewing with the cell 
rather short and broad, the Hindwing with the cell rather long and narrow. Forewing 
with the apex slightly rounded off, the sub-costal nervure four-branched, the first 
branch emitted before end of cell, the second at or beyond the end, the third and 
fourth forming a small fork at the tip of the wing; the upper radial is thrown off from 
the sub-costal considerably beyond the cell; middle discocellular short, straight, lower 
one long, slightly curved, oblique and somewhat angulated. 
The “ clouded yellow ” form a very distinct group, and are very numerous in 
species, especially in Central Asia. The males are generally of a yellow colour, varying 
from light sulphur-yellow to deep orange, the latter being sometimes flushed with 
purple, so deep in one or two instances as to appear almost black; some species are of 
a dull green. Some of the females are coloured like the males, many are Albinos, and
