epots R^ — ]VP either separate or fused with the postdiscal jiatches, iu which case 

 bars R' — M- are vestigial ; postdiscal spots always large, except upper three, about 

 6 to 8 mm. wide at SM-, the series oblique ; no distinct admarginal spots. Hind- 

 wing : a mediauo-discal band from costal to abdominal margin, white, straight, at 

 right angles to H', narrowest between SC- and R', much shaded with olive bufi' or 

 blue (except in front), bordered with that colonr at both sides ; submargiiial white 

 spots as in S, sometimes obsolete, excejjt the last ones; admarginal spots less 

 conspicuous than in c?, often more or less obsolete. 



Underside : similar to that of S, disco-postdiscal creamy or milky white patch 

 of forewing large, no discal bar M- — (SM') ; tails less pointed, sometimes slightly 

 spatulate. 



Length of forewing : <?, 34 — 41 mm. 

 „ ,, ?, 39 — 45 mm. 



Tenth tergite of abdomen (S) rounded ; clasper essentially as in Ch. ackaemenes; 

 penis-funnel shorter than in that sjjecies, otherwise similar in shape ; penis with a 

 triangular ridge about 3 mm. before end, similar to that of C/i. etkeocles, but dorso- 

 lateral ; the size and outline of the ridge is variable ; there are often some small 

 teeth before the ridge. 



Hub. Tropical West and East Africa, and Madagascar. 



The geographical representative forms which we unite here under one species 

 are constantly and conspicuously diiferent in the width of the postdiscal band across 

 the upperside and in some other details ; the East African tavetensis stands exactly 

 intermediate between the West African etesipe and the Malagassic cacuthis, while 

 abyssinicus connects taeetensis with etesipe.

cJ. Witiffs above, band broad. Forewing : rather more elongate than in 



etesipe etesipe, outer edge denticulate, postdiscal band 7 to 10 mm. wide behind 

 SM-, 5A mm. behind M= ; white discal spot M' — M- touching or almost touching 



postdiscal patch ; admarginal sjiots small, last two seldom fused. Hindwing : 



white costal patch C — SC^ contiguous with blue postdiscal one, blue ])atch SC- — IV 

 about 6 mm. long, band not interrupted from R' to (SM'), broader from R' to M- 

 than black outer area, outwardly concave between veins R' — SM^, crossing M 

 between bases of M' and M-, generally two white spots SC" — R- marked within 

 baud close to its proximal edge; admarginal, rufous red, spots 80" — R- present as 

 a rule, but often obsolete. 



Underside : white colour somewhat more extended than iu the other two races. 



Forewing : submarginal bars R^ — M' present, discal bars M- — SJP close to 



median bars. 



? . Wings above. Forewing : markings from M- to costal margin pale tawny 



ochraceous or whitish ochreous buff ; discal spots R' — M- fused with the postdiscal 

 ones, respective median bars vestigial within the patches thus formed, postdiscal 

 and discal spots R- — R^ joined together by means of chestnut scaling which extends
