the ground-colour ; in cliscoidal cell, a little beyond its middle, a 

 sliglitly-angulated dark-brown transverse stria, preceded by a shorter 

 striate marking, sometimes broken into two small spots. Hind-ioing : 

 a very short dark stria (or two small spots) in discoidal cell near base ; 

 two irregular dark transverse striae from costal to submedian nervure — 

 one before, the other about, middle — of which the first is exteriorly 

 edged with some indistinct whitish scales ; outer stria much more irre- 

 gular than the inner; ocelli as above, but their pupils smaller, their 

 rings yellow, narrower, and enclosed in thin outer rings of dark-brown, 

 and the black containing traces of a very thin bluish crescent ; two 

 additional, rather duller, but similar ocelli near costa, before the others ; 

 both interiorly and exteriorly the ocelli are bounded by some whitish 

 or whitish-violaceous clouding. 



This fine form of Leptoneura seems to be sufiiciently distinct from 

 L. ChjtiLS (Linn.), to be ranked as a separate species. The female still 

 remains unknown to me, but, considering how rarely that sex of Clyhis 

 proper is taken in comparison with the very numerous males, this is 

 perhaps not to be wondered at in the case of a form that appears to be 

 very local. The male L. Oxylus differs from L. Clytus in the following 

 respects, viz. : — ( i ) Its much larger size, Clytus not expanding above 

 2 2 inches, and being generally not more than 2 in. 4 lin. across the 

 wings; (2) its paler colouring throughout; (3) the proportionally 

 smaller and invariably triple ocellus of fore-wing, which in Clytus is 

 rarely more than double, and, in the instances where it is triple, the 

 lowest (or third) factor of the compound ocellus is small or minute ; 

 (4) the greater width of the creamy stripe beyond this ocellus ; (5) the 

 whitish hind-marginal border of fore-wing ; (6) the more irregular and 

 broken character of the macular creamy stripe across disc of fore-wing ; 

 (7) the more distinct ocelli of hind- wing, and their conspicuous pale 

 fulvous (instead of dull fulvous) rings ; (8) on the under side of the 

 hind-wing the ocelli are much blacker and their yellow rings much 

 brighter ; while (9) the two dark striae are very much less irregular, 

 the outer one projecting farthest from base on the radial nervule, so 

 that the space between the strife is widest at that jDoint, instead of on 

 the third median nervule ; and (10) the whitish edging of the striae is 

 either wanting or very faintly present, and the basal broken stria of 

 Clytus is all but obsolete. A structural difference is noticeable in the 

 antennge, which are proportionally shorter in Oxylus ; they are also of 

 a paler and more yellowish rufous. 



Colonel BoAvker sent tliis butterfly from Butterwortli, Kaffraria Proper, as 

 long ago as 1861, and afterwards from the Bashee Eiver in the same territory. 

 Mr. "W. S. M. D'Urban informed me that he had noticed this large " Variety 

 A." of L. Clytus in the then colony of British Kaffraria ; but it was not until 

 March 1875 that Colonel Bowker succeeded in taking specimens on the west 

 bank of the Kei Eiver, in the division of East London. I have not heard of 

 the butterfly occurring in Natal, or elsewhere in South Africa than within the 

 limited range indicated.
