412 DE. A. G. BUTLEE ON LEPIDOPTEEA [May 17. 



Wet form, tf g , Mombasa, 4th January, 1897. 



I now have another proof of the absurdity o f calling this very 

 distinct species a variety of T. mutans, inasmuch as the dry form 

 is seen to differ from the wet chiefly in the redder colouring of 

 the bands on the under surface, whereas in T. mutans the whole 

 under surface of the secondaries and of the apex of primaries 

 becomes clay-coloured with a pink suffusion, the bands being 

 indistinct.
