TTANA. 15 



The two examples associated under this name by Mr. Walker are not, as he supposed, 

 sexes of one species. Both are females, one of them being that sex of my T. speculatrix ; 

 curiously enough, the very considerable differences between the latter aud Walker's species 

 do not appear in the description.
