along liiud-margiu ; tails black, whito-tipped, the lower one orange at 

 base. Cilia ochre-yellow. Under side. — Fale whitish-ycllovj, ivith 

 orangc-ochreous or orange, mcsially golden-spangled transverse strij)es, 

 finely hut distinctly hlach-edgcd on hoth sides. Fore-wing : three stripes 

 from costal edge, viz., first short, quite transverse, before middle to 

 median nervure or a little below it, — second long, oblique, fuscous 

 below first median nervule, extending to submedian nervure not far 

 before posterior angle, — third beyond middle, quite transverse, abruptly 

 terminating (with rounded, black-edged extremity) just below third 

 median nervule ; between second and third stripes a costal spot of the 

 same colouring ; a similar sub-basal spot in discoidal cell; two sub- 

 marginal black streaks, of which the inner is thicker and more irregular 

 inferiorly ; hind-mai'gin with a very well-defined linear black edging. 

 Hind-icing : base and inner margin to beyond middle rather widely 

 bordered with orange-ochreous, edged outwardly by a series of five 

 small black spots ; two stripes from costal edge of a brighter orange 

 than those of fore- wing, viz., first very long, oblique, from before 

 middle to below first median nervule, where it is sharply angulated, 

 and whence its black edges only are continued to inner margin, — the 

 second almost parallel from a little before apex to third median 

 nervule, where (like the first at its angulation) it joins an irregular, 

 iuferiorly-wddened, golden-spangled orange inner submarginal streak 

 terminatino- at anal ansfle : outer submaro-iual black streak and hind- 

 marginal linear edging as in fore-wing ; anal-angular black spot larger 

 than on upper side. Cilia orange. Collar rufous. 



^ Like ^, but blue in fore-wing occupying more of discoidal cell, 

 and usually more or less obscuring first transverse ochre-yellow stripe ; 

 two outer stripes of fore-wing broader, and usually more wddcly con- 

 fluent at lower extremities. Under side. — Quite as in $. 



Numei'ous specimens of l)oth sexes collected in Basutoland by Colonel 

 Bowker, as well as one which I took in Griqualand West, are rather smaller 

 than the Natal examples, and the orange of the under-side stripes, Sec, is 

 replaced by pale creamy-ochreous with a slight ferruginous tinge ; the tails 

 of the hind-wings are also rather shorter. 



I have had great difficulty in deciding whether Westwood's Natal ensis is 

 the butterfly above described, or the species immediately following. There is 

 no description given in the Genera of Diurnal Lejndoptcra, and only the 

 upper side of an apparently worn individual (? female) is figured. The pre- 

 valent form on the coast of Natal is the species {Masilikad of Wallengren, 

 Natalensis of Hopffer and myself) with purple fasciai on the under side ; and 

 in the British Museum Collection this was the species labelled " Natal ensi)<," 

 although associated with it was the single Sierra Leone individual mentioned 

 in my Itlwpaloccra Africie Australis (p. 228) with orange fascia>. When 

 in 1868 {loc. cit.) I described the orange-banded form as a distinct species 

 (.4. caffer), I found that Ilewitson {np. cit.) had figured it as Natalensis, 

 Westw., giving the upper side oi a. $ and the under side of a 5 . Re-exa- 

 mination of ilewitson 's figure of the upper side in the Genera, in com- 

 parison with a large number of specimens, has led me to conclude — especially 

 in view of the lars^e size of the orange anal-angular marking in the hind-
