 by a row of six whitish spots. The body is of the same colour as 

 the wings ; the antennae are brownish, and annulated with grey above 

 and ferruginous below." — Enc. MUh. 



Hab. Brazil (Godart) ; Venezuela (Westwood) . 



Although this species is stated, in the ' Genera of Diurnal Lepi- 

 doptera,' to be in the British Museum Collection, I have not been 

 able to find any specimens that agree with the description ; it may 

 possibly be allied to E. byses, Godart.

"About 1^ inch in expanse. Wings slightly dentated, brown, 

 rather dark in some parts ; upperside without spots. The underside 

 shows three very dark lines, transverse and waved ; between the 

 central and outer ones the hind wings have a row of five spots, only 

 the three exterior ones black, with a double white pupil and orange 

 iris ; the third and fourth yellowish, and at times somewhat reniform ; 

 the front wings also have two similar yellowish spots surmounted by 

 a bipupillate ocellus. There is a double blackish line along the 

 posterior margin of all the wings, scarcely perceptible on the upper- 

 side." — Enc. Meth.
