Euptychia tricolor, Hewitson, Ann. & Mag. Nat. Hist. vi. p. 440 

 (1850); Westw. & Hewits. Gen. Diurn. Lepid. p. 373. n. 15, pi. 65. 

 f. 3 (1851). 



Hab. 3 , Tapajos ; Fonteboa. B.M. 



2 , Tapajos (Colt. Bates). 



This is one of the most distinct and beautiful species of Euptychia: 

 specimens from Fonteboa are even more exquisite in colouring than 

 the one figured in the ' Genera ;' they have a broad ill-defined sub- 

 costal streak of metallic blue green in the front wings. The only 

 specimens of the female of this insect which I have seen are in Mr. 

 Bates's collection ; they are very similar to the females of E. chloris. 



101. Euptychia batesii, sp. n. (PL XL. fig. 16.) 



cJ . Ala supra fuscce, omnino viridi purpureoque micantes : corpus 

 olivaceo-fuscum ; antennis supra fuscis, albido fasciolutis, prce 

 flavescentibus, nigro acuminatis, subtus Jlavis nigro acuminalis. 



Alee subtus albidce, minime roseo micantes, fasciis duabus mediis ob- 

 liquis rubris ; fascia lata apud marginem posticum fusca, ocellos 

 includente ; tinea submarginali fusca, anticarum apud apicem an- 

 gulis alternis undata, posticarum undata ; lineis duabus marginali- 

 bus fuscis, posticarum undulatis : anticce ocello uno subapicali 

 nigro, fulvo cincto argenteoque pupillato, punctisque duobus mini- 

 mis intersectis argenteis : posticce ocellis quinque fulvo cinctis, 

 primo, secundo et quinto nigris argenteo pupillatis, primo minimo, 

 quinto maximo et bipupillato, tertio et quarto ferreo-argenteis 

 iridibus fusco conspur cutis : corpus ochreo-fuscum.

5 . Alee supra pallida violascentes, lineis marginalibus distinctis : 

 posticw macula subanali uvali nigra brunneo cincta. 



Hab. Tapajos {Coll. Bates) ; Para {Coll. Salvin). 



The female of this species bears a strong general resemblance to 

 our variety of E. ocypete, and even more closely resembles E. helle, 

 but may be at once distinguished from these by the form and posi- 

 tion of the central bands, which in E. ocypete and E. helle are rather 

 nearer to the outer margin ; the central ocelli also are bipupillate in 

 these two species.
