262 SOUTH-AFEICAN BUTTEEFLIES. 



others indistinct and sub-ocellate (being outwardly marked with a 

 fuscous dot) ; inner of two hind-marginal white linear streaks bright 

 silvery. 



$ Duller, paler throughout ; ochreous-yellow band in hind-wing 

 usually proportionately narrower ; transverse fuscous streaks before 

 middle much more apparent, broader. Fore-wing : first spot of short 

 subapical row enlarged, whitish, rather conspicuous. Under side. — 

 Paler, more inclininrj to ochreous ; all the markings more conspicuous; 

 the paler discal space well marked ; its traversing whitish ray rather 

 suffused, but continued across hind-wing. 



In a small female, taken near D'Urban by Colonel Bowker, the fore-wing 

 presents in a narrower form the median transverse chocolate-red band of the 

 male, and the ochreous-yellow band in the hind-wing is very broad, having 

 only a little brown irroration externally and interiorly. 



Southern examples of this butterfly are usually considerably larger than the 

 type-form from the West Coast of Africa, and the under side of their wings is 

 rather darker, especially in the discal area, — in which latter, however, the 

 traversing whitish streak is much more distinct, being sometimes obsolete in 

 Gold Coast specimens. The angulation of the wings is also much more pro- 

 nounced in South-African examples.^ 



Colonel Bowker has sent me the paired sexes, taken at D'Urban, l^atal, in 

 May 1880. In this case the female was the small one above mentioned. As 

 noted under U. Hiarbas, a female not separable from Dryope (but with a 

 narrower than usual ochreous-yellow band in hind-wing) was captured in 

 copula with an ordinary male of the former species. A very perfect male 

 Dryope, received from Delagoa Bay (where it was taken by Mrs. Monteiro), 

 almost exactly agrees with the female just mentioned in the comparative 

 narrowness of the hind-wing band ; but even in this individual the band is 

 twice as wide as in the male Eurytela, which I have described as Variety A. of 

 E. Hiarhas. 



Apart from its colour, the width of this band in both wings, the browner 

 ground-colour, the fuscous streaks before middle, and the male character of 

 a chocolate- red median band are the chief features distinguishing Dryope 

 from Hiarbas on the upper side ; while on the under side, the more ochraceous 

 general tint, the less broken and less angulated striaj, the want of any dis- 

 tinct discal stripe in the hind-wing, and the presence, instead, of two con- 

 spicuous costal lunules heading a row of very indistinct imperfect ocellate 

 marks are all distinctive of Dryope. 



I did not meet with this species in Natal, but Colonel Bowker has been 

 more fortunate, taking several examples near D'Urban in August, December, 

 and February, and two at the mouth of the Tugela River in July. He 

 describes it as having the same habits as Hiarbas, but as much rarer. I have 

 not heard of its occurrence to the south of !N"atal. 



^ I think that E. Narinda, Ward, from Madagascar, though closely allied to E. Dryope, 

 is entitled to recognition as a distinct species. It is small (about the size of the West- African 

 Dryope), but the wings are even more angulated than those of the Southern examples described 

 in the text. On the upper side the ochreous-j'ellovv band in the male begins neai'er apex of 

 fore-wing, and is very much broader in both wings ; and in the fore-wing its inner side is 

 deeply pierced by the dark-clouded nervules, while in the hind-wing it occupies greater part 

 of surface from before the middle. In the female, the only marked difference in the band 

 is its width in the fore-wing. In both sexes the hind-marginal striae are straighter, not so 

 lunulated. The under side is very different ; all the striae being straighter, narrower, and 

 of a yellower ferruginous ; the hind-marginal clouds very pronounced ; and the white discal 

 streak very well marked.
