Closely allied to E. gemma, from which it differs in being much 

 larger, having the apex of the front wings subangulated and the 

 outer margin of the hind wings sinuated ; the wings above reddish in 

 some parts, with much larger marginal black spots ; below, the cen- 

 tral streaks are more distinct, reddish, and different in outline.

Alee supra f usees immaculate ; anticee subtus plerumque immaculate ; 

 posticcB ocellis nigris scepius ovalibus, atomis argenteis pupillatis.

Alee supra fuscce, lineis duabus marginalibus valde indistinctis : 

 corpus cinereo-fuscum, antennis ferrugineis. 



Ala subtus pallidiores, violascentes, area apicali posticarum vires- 

 cente vel violascente , lineis duabus mediis fuscis, ad costam anti- 

 carum divergentibus, externa posticarum medio angulata, margine 

 tenuissime fuscescente, linea marginali tenui alteraque submar- 

 ginali fuscis : posticee ocellis quinque ovalibus et rarissime uno 

 minimo apicali, primo et quinto minoribus, nigris, brunneo cinctis, 

 fusco circumcinctis et atomis argenteis pupillatis : corpus cinereo- 

 fuscum.

Closely allied to E. pacamis, but apparently differing in the posi- 

 tion of the lines below, and in size. 



121. EUPTYCHIA MIMA, Sp. n. 



Preecedenti simillima, sed minor, lineis mediis subtus ad costam anti- 

 carum magis approximantibus, externa posticarum medio excavata : 

 anticee ocel/o purvo apicali : posticee paulo violascentes, ocellis sex 

 minoribus marginem approximantibus.

 Hab. Tapajos {Coll. Bates). 



Very like the preceding species, from which it differs in being 

 much smaller, with the lines below differently formed, and the ocelli 

 smaller and nearer to the outer margin.
