or oval ; those composing the innermost row are smallest, and 

 slightly and somewhat variously lunate. Fringe white. 



From one example taken by the late Prof. Gabb in Costa Rica, 

 now in Mus. Strecker. 



On the upper side, omitting the tails, this insect bears a close 

 resemblance to the females of Eumeeus Toxea and Minyas. 



There is, as far as I am aware of, but one other species of this 

 genus known, T. Eunomia Hew., 1 from New Granada, from which 

 the one here described is entirely distinct. 



Agrias Amydon, Hew. 9 



Expands 3j inches. Head black with four minute white spots 

 above ; palpi } T ellowish white. Body above deep ochraceous 

 orange, below black with pale spots and marks. Wings, pri- 

 maries broader than in the male ; exterior margin straight until 

 near inner and outer angles, where it is rounded. 



Upper surface. Primaries, basal half, or rather more, bright 

 ochraceous, deepening in tint towards the base ; the outer part of 

 wing black ; this latter color starts at the inner angle and extends 

 across in an arched line to within the middle of costa, forming a 

 large triangular patch, which covers the outer part of the wing; 

 a dash or an abbreviated band of black extends from inner angle 

 along inner margin to over half its length ; a band of three whitish 

 yellow spots cross the black color towards the apex. 



Secondaries, black with a small patch of deep ochraceous near 

 the base, and a whitish edging at the apex. 



Under side of all wings colored and marked as in the male, with 

 the exception of the ground-color of primaries, which is ochre 

 yellow instead of red. 



Described from a single example which came to me in a lot of 

 several thousand butterflies, taken at or near Pebas, on the Peru- 

 vian Amazon. 



On the upper side this insect is the exact counterpart on a 

 gigantic scale, of Gatagramma Sinamara Hew., and (if my ex- 

 ample, received from Mr. Hewitson be that species) of G. Amazona 

 Bates, which is. doubtless the 9 of G. cynosura Hew., and further 

 between which and the figure of G. Sinamara I can see no dif- 

 ference.
