"Alis integerrimis , fuscis, supra ocello unico, subtus striga ferru-

" It differs from eurythris in being smaller, the upperside and the 

 underside of the front wings having only a single ocellus, and the 

 underside of the hind wings only three ocelli — one near the margin, 

 and two (the outer one very small) near the anal angle, — finally in 

 that it only has one brown line, instead of two, in the middle of the 

 disk of each wing." — Enc. Meth.
