? . Body above somewhat darker tliau in <S abdomen beneath without the 

 black lines of lucretiiis. 



Wings, upperside, as in S, but basal area of forewing mnch less bright and less 

 extended, cinnamon rufous, the disco-postdiscal band buff yellow, distallj* tinged 

 with orange rufous, seldom shaded with brown, broader than in cJ, measuring 

 9 mm. in width at SM'^ the discal portions of the j)atches R^ — M'^ larger than in S ; 

 median spots SC^ — W pale ochraceous rufous ; admarginal spot as in S, but spots 



SC — M^ larger than in S , about equal in size. Hindwiug ; disco-postdiscal band 



buff )'ellow, wider than in <?, 8 mm. broad at R', edged externally with rufous 

 orange ; admarginal orange rufous band more even in width than in S , being com- 

 paratively narrower in middle than in the other sex, its proximal edge evenly 

 convex between veins down to R^ ; band of both wings sometimes suffused with brown. 

 Underside : paler than in S, the interspaces between the heavy bars more 

 glossy ; discal and postdiscal interspaces of forewing and large halfmoons at 

 outside of discal bars of hindwiug as well as cell of forewing buff, more or less pale, 

 discal band of hindwiug silvery as in c?, but wider, or pale yellowish buff like discal 

 patches M' — SM- of forewing ; tails longer thau in S , the upper one slightly 

 spatnlate, 8 to 9 mm. long, the second pointed, (3 to 7 mm. long. 

 Length of forewing : c?, 38 — 42 mm. 

 „ „ ? , 45—49 mm. 



Hook of clasper irregularly denticulate at upper edge, rather strongly curved, 

 acute ; penis curved before the end, no armature except a feeble ridge about 2| mm. 

 from the tip which bears some small teeth, the ridge is oblique, turning proximally 

 towards the left side ; penis-funnel somewhat narrower towards the end, apex 

 rounded when seen from above, apical margin turned downward to form a rather 

 heavy hook. 



Vein D^ of hindwiug in both sexes before M', as in boueti. 



Hab. West African Forest Region, from Sierra Leone to Angola and Unyoro ; 

 Fernando Po, coll. Grose-Smith, In the Tring Museum 15 ^cJ, » ? ? from: 

 Sierra Leone ; Gold Coast ; Warri, Niger Coast Protectorate, February and April 

 (Dr. Roth) ; Congo ; Lukolele, Bopoto, Kassai ; two and three days' march from 

 Ft. Beni, Aruwimi Forest, May 6. 7. 1899 (Dr. Ansorge) ; Fajao, Unyoro, 15. vii. 

 97 (Dr. Ansorge). This is a close ally of Ch. boueti, of which it may be called 

 the West Ai'rican representative, though the two insects cannot very well be united 

 to one species, the differences between them being too great. 



Charaxes cynthia has apparently developed into two subspecies, the one 

 inhabiting the northern parts of West Africa from Sierra Leone to the Niger, the 

 other ranging from Cameroons to Unyoro. W^e have not seen sufficient material of 

 t]ie femiile sex, and therefore do not give a name to the Congolese form, but point 

 out the following differences between the males : 



Sierra Leone to Niger : Postdiscal band of forewing above posteriorly obviously 

 paler than in front ; discal band of hindwing ferruginous buff yellow, edged with 

 orange rufous. White discal band of underside of hindwing 2 to 4 mm. broad 

 before SC^ 



Cameroons, Congo, to Unyoro : Band of forewing above not distinctly jialer 

 behind than in front ; band of hindwing orange rufous, little paler proximally ; 

 orange rufous admarginal band of hindwing above and beloiv wider than in cijiithia 

 cijnthia. On underside the white discal baud is on the whole narrower thau in the 

 northern race.
