and Guiana in the east to the State of Panama, whence we have seen two specimens, 

 one in our own collection which we figure, and one in that of Dr. Staudinger, both 

 from the neighbourhood of Chiriqui. The figure of the male is taken from the only 

 example of that sex we have seen ; it is in the British Museum, and was captured by 

 Buckley in Ecuador ; the type (now in our possession) and all the others we have 

 examined are females.

Hah. Costa Rica (Van Patten) ; Panama, Chiriqui (Bible 1 , Trotsch). 



We have three female specimens of this species before us — two from Chiriqui, lent 

 us by Dr. Staudinger, one of them being the type of the species ; the third is from 

 Costa Rica and is now figured. 



Without the male we cannot be sure of the position of this species ; but it has some 

 resemblance to T. cadmus, and we therefore place it here. 



3. No alar stigma ; apex of primaries acute ; wings beneath rufous, crossed by three 

 nearly straight white lines. (Species 38, 39.)

This species and the next are allied to T. cegiades of Felder ; but T. farina differs in 

 having a much wider dark border in the male. We have only two specimens— a female 

 said to be from South Mexico, but without precise locality, and a male captured by 

 Mr. Champion in the mountains between Quiche and Totonicapam, at an elevation of 

 between 7000 and 9000 feet above the sea ; the latter is figured.
