When the plates were drawn I believed that this species might 
be only a variety of Y. /tonia, as it is the only other species 
which has seven ocelli on the posterior wing; I now think it better 
to consider it as a distinct species. Itis larger than Y. Itonia, has 
a distinct band of darker colour crossing the middle of both 
wings on the upperside, and is easily known from all the other 
species by having two transverse bands on the underside of both 
wings, and on the posterior wing a third band in which the ocelli 
are placed. It is from the Collection of Mr. Wallace. Bears 
great resemblance to Y. Baldus, but instead of having the ocelli 
in pairs and apart as in that species it has them in a line.
