and anal veins approximating closely on the hind border; hind side of
the discal areolet forming a right angle, and emitting thence the stump
of a vein. Length of the body 4-1/2 lines; of the wings 9 lines.
67. ANTHRAX DEGENERA, _Walk._ See Vol. I. p. 15. _var. Mas et Foem._

brown, cinereous at the tips; fore branch of the cubital vein deeply
curved, with its angle emitting the stump of a vein. Length of the body
3-1/2-5 lines; of the wings 8-12 lines.
This species is closely allied to _A. fervida_, and, like the two
preceding species, approaches the Australian group (subg. _Neuria_),
which is distinguished by the long wings with contorted veins.
