 We recognise two geographical races : 



a. CL nitebis nitebis (Nov. Zool. VII. t. 6. f. 6, ? ). 



Nymphalis nitebis Hewitson, I.e. 



Charaxes nitebis, Butler, Proc. Zool. Soc. Land. p. 635. d. 51 (18G5) (Celebes) ; Stand., l.c. ; Eothsch., 



Iris V. p. 4.37. t. G. f. .S, ? (1892) (S. Celebes). 

 Xymphalis nitebis, Pagensteober, Abh. Senl: GeselUch. XXIII. p. 403. n. 188 (1897) (Minahassa ; 



Dongala). 



cJ. Discal series of bars of underside not heavier than median one, the upper 

 discal bars of forewing rather feeble ; median interspace M' — SM- of forewing 

 narrower than the median interspaces before it ; black submarginal dots of hind wing 

 smaller than the greyish blue ones. 



? . The pure creamy white portions of the discal patches C — R' of the hindwing 

 above wider than long ; discal lunnles R'— M* of forewing 1 — IJ mm. thick at inter- 

 nervular folds ; on underside the median interspaces of forewing and the black and 

 blue dots of hindwing as in c?. 



Hab. Celebes. In the Tring Mu.'^enm 2t <? cJ, 5 ? ? : from Maros country, August 

 and September 1891 (W. Doherty), Dongala and Tawaya, Palos Bay, August and 

 September 1896 (W. Doherty), Toll Toli, November— December 1895 (H. Frnhstorfer). 



We do not find any constant difl'erence between the examples from North and 

 South Celebes. The males from the South are on the whole somewhat paler beneath 

 than those from the North, and onr fimg\e female from the Sonth has the postdiscal 

 spots of the forewing above rather huffish. 



b. Ch. nitebis sulaensis Rothsch., subsp. nov. 



c?. The discal spots SC° — R" of the forewing above generally larger than in 

 nitebis, the postdiscal spots M* — SM- less often absent ; submarginal dots M^ — SM^ 

 present. The underside is less pale than in nitebis, the discal bars are heavier black, 

 the median interspace M^ — SM" of the forewing is broader than the interspace 

 M' — W-, the black submarginal dots of the hindwing are much larger than in nitebis, 

 and the blue spots at their proximal side brighter blue. 



? . The discal spots of the forewing aboi-e are rather wider than iu nitebis and 

 purer cream-colour, lunule R^ — M' nearly 2 mm. thick at internervular fold, small 

 creamy dots beyond upper angle of cell more distinct, admarginal spots M'— SM' 

 better marked, the others faintly vestigial ; on hindwing the creamy white discal 

 spots are larger, being longer than broad, the admarsriual spots are obviously paler 

 than the disc, and the black submarginal spots are larger than in nitebis nitebis. 



The umlerside exhibits the same differences from nitebis as the 3 does. 



Hab. Sula Islands. In the Tring Museum from : Mangoli (^yjoe), W. Doherty, 

 October and November 1S97, 13 SS, 1 ?; Besi, W. Doherty, October 1897, 1?; 

 Mangoli (Dr. Platen), 1 cJ. 



b^. Forewing above without a series of creamy white halfmoons on disc. 



c^. Up]ierside of hindwing without a band of large postdiscal, pale blue, 

 halfmoon-shaped patches. 

 «■*. Forewing above without a creamy, postdiscal, narrow band. 



rt'. Bars of underside not pale chestnut, white band of forewing, if 

 present, not considerably narrowed behind. 

 a'. Forewing above not blue iu S, white band not widely inter- 

 rupted at R^ in ? .
