marked with a row of four minute, almost obsolete, imperfect, dark- 
brown annulets between upper radial and second median nervule at 
some distance from kind-margin, wkick is tinged with brown in its 
middle portion. Hind-wing : costal border bounded by subcostal ner- 
vure and its first nervule (except for a very slight infringement on 
discoidal cell close to base), its costal half much hatched with brown, 
but the rest usually clear cream-colour ; all the remaining area brown 
strongly tinged with violaceous ; a more or less interrupted darker- 
brown curved fascia, commencing widely on first subcostal nervure, 
narrowing into a linear form between extremity of discoidal cell and 
first median nervule; a submarginal row of six annulets like those in 
fore-wing but larger, and their creamy centres more conspicuous 
(especially the first, whose ring is more or less suffusedly widened), 
between first subcostal and inner margin, the last being a double spot ; 
a narrow hind-marginal ochreous edging. 
The sexes do not differ to any appreciable extent in either marking 
or colouring. 
I have followed Mr. Butler {loc. cit.) in treating this very pro- 
nounced Southern form as distinct from M. Parmeno (Doubl.) of the 
West Coast of Africa."^ Mr. Butler has not characterised M. diversa, 
but its most obvious distinction is its much greater size, Parmeno only 
expanding 2 in. 5—8 lin. In markings it conspicuously differs in the 
comparatively broader bar of the fore-wing, which in the ^ Parmeoio, 
moreover, is indistinct whitish instead of ochre -yellow, and more 
developed border of the hind -wing ; while the general ground of the 
wings is paler and duller above. The sexual badge of the $ is more 
oval, more densely hairy, and not circumscribed by a pale ring. On 
the under side, the pale apical patch in the fore-wing in Diversa is a 
good distinction, — that part in Parmeno being but little paler than the 
rest of the wing. 
There is much similarity in outline, size, and general appearance 
between M. diversa and M. Lcda, and the imperfect blind ocelli of the 
under side are in number and position precisely the same in both 
species (though replaced in the typical Leda by complete ocelli), but 
the former seems as constant to one pattern of colouring and marking 
as the latter is variable. The absence of any ocellate spots on the 
upper side, combined with the position of the conspicuous ochre-yellow 
bar on the fore-wings, readily distinguish Diversa, which is further 
noticeable for longer projections of the hind-wings, and for the upward 
and outward curve of the longest projection (at the end of third median 
nervule). The J is also at once recognisable by the conspicuous sexual 
badge on the fore-wings — a feature totally wanting in the $ Leda. 
^ I captured a ? Parmeno at sea, about 1 90 miles due West of Sierra Leone, and saw two 
other examples of the same species, on the 24th November 187 1. The day was perfectly- 
calm ; but quite a variety of Lepidoptera and other insects came about the ship. I was 
much surprised to find such shade-loving inactive SatijrincG as this butterfly and several of 
two species of Myealesis among the visitors from the distant shore.
