is almost certainly the same as Mr. Distant's genus Simiskina. I 

 have seen the type specimens of Simiskina fulgens, Distant, in 

 Dr. Staudinger's collection, and find that they are conspecific with 

 "Poritia" potina, Hewitson. The name Massaga is also preoccupied, 

 having heen used by Mr. Francis Walker for a genus of African 

 Moths in part ii. of his " List of the Specimens of Lepidopterous 

 Insects in the collection of the British Museum," page 358 (1854). 

 I give below a key to the genera of the Poritia group by which it 

 should be easy to recognise them all.
