3. Prepona phedra, sp. n. 
P. demophonti similis, sed posticis ocellis septem submarginalibus notatis; alis subtus multo magis obscuris, 
fasciola per cellulam anticarum valde sinuata, linea nigra transversa posticarum valde interrupta ad venam 
subcostalem et ad venam medianam. 
Hab. Panama, Volcan de Chiriqui (7ré¢sch). 
We are indebted to Dr. Staudinger for bringing this species under our notice, as no 
specimens have as yet been sent to us. It seems certainly distinct from both P. demo- 
phon and P. camilla, the distinct row of submarginal ocelli of the secondaries alone 
rendering it not difficult of recognition ; in addition to this, the transverse black band 
of the secondaries beneath is almost as much broken as in P. amphitoe, which again 
differs in the silvery tint of the wings beneath.

There is scarcely any difference between this species and P. demophon on the upper- 
side, but beneath it is of a silvery grey (not ochreous), and the lines are always black 
or dusky, and that crossing the centre of the secondaries, although taking much the 
same direction as in P. demophon, is always strongly angulated, which is not the case 
in the other species. We find that certain specimens vary much in the same direction 
as in P. demophon, being clouded with an obscure ashy colour. 
It is tolerably abundant in Central America; but Mr. Bates says it is less common 
than P. demophon throughout the Amazons region ?.
