lights. The brand at the end of the cell is circular and simple, 

 not compound as in T. f abulia. Under side with markings much 

 like T. fahuUa, but paler and more distinctly edged with white. 

 The transverse band of the fore wing is more irregular and 

 appears to be closer to the end of the cell, whilst that on the hind 

 wing appears to be less inclined to break up into spots. The 

 ground-colour is paler and the red patch at the extreme anal angle 

 is almost obsolete.

 margin of the fore wing being broadly white from the base almost 

 to the outer angle, slightly bluish near the base, and in the hind
