SATYEIN^. 117 



marked with a row of four minute, almost obsolete, imperfect, dark- 

 brown annulets between upper radial and second median nervule at 

 some distance from hind-margin, which is tinged with brown in its' 

 middle portion. Hincl-ioing : 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 ^ Parmeno, 

 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. Leda, 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 $ 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 190 miles due West of Sierra Leone, and saw two 

 other examples of the same species, on the 24th November 1871. 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 Sati/rinw as this butterfly and several of 

 two species of Mycalesis among the visitors from the distant shore.
