Ega and Santarem. In Coll. B. M. 



It will be seen in the above synonymy of this genus. Walker 

 invariably mistook females for males, the different structure of 

 the frenulum in the sexes being evidently unknown to him. 



Apistis angusta.

 Ega and Piio Negro. Types in Coll. B. M. 

 Plaxia atriplaga of Walker appears to be a Thermesia. It 

 differs slightly from T. gemmatalis in the form of its primaries, 

 but otherwise I have not discovered any structural difference, 

 whilst the pattern is very similar.
