of which the upper two or four are often obsolete, aud these followed again by 

 black dots which are generally present at least between veins R'-* and SM- ; discal 

 bars short and thin, postdiscal ones mostly obsolete, or only vestigial ; tails pointed, 

 upper one 5 to T mm. long, second 3 to 4| mm. 



?. Wiii(/s above purplish seal brown, somewhat paler at base, long hairs in 



basal area of hindwing olivaceous. Forewing : a transverse, curved, discal band 



from costal to inner margin, 1 to 2 mm. from cross-veins, white, slightly shaded 

 with violet at edges, especially behind, its iimer edge triangularly sinuate at hinder 

 side of R^, convex between the veins, but mostly concave between M- and SJI', 

 enter edge sinuate between R- and R' in most specimens, more or less indented 

 upon veins, the band widest (8 to 12 mm.) between M' and M-, but on the whole 

 of nearly even width, jiatch at internal margin often prolonged, the streak along 

 costal margin also generally prolonged basad ; postdiscal series of spots represented, 

 at least, by two white spots SC* — R', which are larger than in cJ, often shaded 

 with violet at edges, aud followed in many specimens by one to four small huffish 

 white dots the last one of which, between M' and M', often touches the band ; 



admarginal buff dots M- — SM- often present. Hindwing : a large white central 



l)atch, much shaded with purple, especially at edges, variable in width, expanded 

 between costal margin aud abdominal fold, proximally limited by median bars 

 C — R", which are vestigial or show through from underside, penetrating a little 

 into apex of cell, or stopping at D', outer edge convex, almost parallel to outer 

 margin, but farther away from it in front than behind, width of patch before 

 R^ 10 to 14 mm., before SC^ 3| to 6 mm., at outer side of band before SC- there 

 is sometimes an isolated postdiscal spot, similar spots occasionally indicated between 

 SO- and R^ more or less incompletely isolated ; abdominal fold bluish white, buff 

 or clay colour distally ; submarginal blue spots as in S , often larger, posterior 

 ones mostly transverse; admarginal interstitial spots as in S, spot SC- — R' 

 generally better marked, coloi;r varying from cream to ochreous, posterior spots 

 sometimes nearly all blue. 



Underside similar to that of S , band of forewing as above, but less curved, 

 patch M- — SM- square or posteriorly narrower than anteriorly, often completely 

 divided by a black streak on (SM') ; discal interspaces of hindwing most pale clay- 

 colour at median bars ; upper tail of nearly even width, not pointed, 8 to 10 mm. 

 long, second pointed, slightly curved frontad, 4 to 6 mm. long. 

 Length of forewing : cj, 42—46 mm. 

 „ „ ?, 46— 52 mm. 



Penis closely resembling that of t'h. bipunctatas, being armed with a sinistro- 

 lateral subapical tooth and, proximally, with a dorsal tooth-like ridge. 



Ilnb. East Africa from Natal northwards to Nyassaland, German and British 

 East Africa ; its northern limit is most likely the Victoria Nyanza and the hills 

 south of the Keuia. In the Nandi country the western Ch. smaragdalis already 

 appears. In the Tring Museum 2SS, 12?? from: Durban, Natal; Rikatla, 

 Delagoa Bay ; Lauderdale, and Zomba (October to December), Brit. C. Afr. ; 

 Mikindani, Germ. E. Afr. ; Mombasa. 



The male» from Natal, Delagoa Bay, Nyassaland, Mozambique, and the 

 coast region of German East Africa do not apparently exhibit any geographical 

 variation, ihn females from Mombasa, British East Africa, differ obviously from 

 the individuals from the other localities mentioned ; while in the Natal ? ? the 

 white baud of tlie forewing above is 8 to 10 mm. distant from outer margin of
