TYANA. 
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 difiFerences between the latter and Walker^'s species 
do not appear in the description.
