Closely allied to T. umbrata, Linn. ; but in that species 

 the purplish-brown band lies between the nodus and the 

 stigma, whereas in T. Tyleri it extends from about the 

 triangle of tlie fore wings to halfway between the nodus and 

 the pterostigma, and the lower basal cell is slightly clouded 

 as iar as the base. The hind wings are clouded from the 

 base to the outer level of the band of the fore wings, but the 

 basal part of the iiind wings is paler than the rest of the 

 clouded portion, especially in the female. 



Described from three males and two females.
