MAMESTRA SEGREGATA Smith. 



No specimens; two in i\Ir. Cockle's collection, May 14. This species 

 is olniouslv variable and a good series is needed. Neither of ]Mr. 

 Cockle's specimens are like the type before me, though I think they 

 are the same species without doul)t; gussata Smith seems to be only a 

 variety of it.
