scarlet, band of primaries and border of secondaries much 

 broader and paler in tint, margin of secondaries black. 



Expanse of wings 60 millimetres.

This is Walker's E. arnica, but not Cramer's.

This may not be a Pericopid, in which case it can be 

 separated as type of Pyrodesma.

The Phalaina militta of Cramer, placed in this genus by 

 Mr. Walker, appears not to be a Pericopid. I doubt if 

 Walker's Lama trifera (Char. Lep. Het.) is a Pericopid. 



The Eucyane uranophila of Walker is a species of Histioza 

 (Zyggenidge) . 



Genus Hyaluega, Hiibner.

2. Hyalurga amazonica, n. sp. 



Differs from the preceding in the deeper colour of the 

 ochreous margins and band of primaries, which are also 

 broadly bordered with dull black, the much broader black 

 border of secondaries, with less-defined central white streak. 



Expanse of wings, $ 57 millimetres, ? 73.
