pale spot placed against it between the points of tlie forks. Underside, 

 both ivings pale oclireous-brown washed with pale violet, the discal 

 macular band of the upperside almost obliterated. Forewing with the 

 markings in the discoidal cell as on the upperside, but much more 

 prominent ; an increasing submarginal series of black spots. Hindioing 

 with a pair of fuscous lines defining the disco-cellular nervules ; a 

 submarginal series of eight linear black spots between the veins, 

 the two posterior ones in the submedian interspace geminated. Female, 

 much paler than the male throughout, but very similarly marked. 

 Foreidng with all the spots of the discal series very much larger and 

 pure white, the two uppermost spots greatly lengthened. Hindioing 

 with all the spots of the discal series white, of nearly the same size 

 as in the male. Underside, hotli wings paler even than in the male, 

 of a more ochreous shade, the markings similar. 



This is a very distinct species and quite easily separable from all 

 those that I have placed before it in the key. The ground-colour 

 of the male on the upperside is quite feminine, being much paler 

 than in any other species of this sub-group of Enthalia. The discal 

 series of spots on the hindwing will separate it from all the other 

 species except E. externa, de Niceville, next described, owino- to each 

 spot standing alone, and the five posterior ones being outwai-dly 

 defined by a black ring ; from E. externa it may be known by its 

 generally paler colour, and the discal series of spots on the fore win »• 

 being smaller and more regular. The female is quite unique, beino- 

 the only species in the sub-group with the discal series of spots of the 

 forewing regularly increasing in width towards the costa, the uppermost 

 spot being extremely wide. The female of E. eson greatly reminds 

 one of the same sex of E. (Tanalicia) puJasara, Moore. 



Described from a single pair of specimens in Herr Geoi'g Semper's 

 collection, to whom I am greatly indebted for the loan of his entire 

 series of this sub-group of Euthalia. These specimens of E. eson are from 

 those collected by Dr. Platen, who obtained ten males and eight females. 



12. Euthalia (Dophla) externa, n. sp., Plate II, Fig. 1, c? ; 2, $ . 



Habitat : Nias Island. 



Expanse : <?> 2*8 ; 9 , 3*3 inches. 



Description : Male. Upperside, both icings shining fuscous, out- 

 wardly paler. Foreiving with the usual black spot in the middle and 

 pair of lines closing the discoidal cell ; a discal irregular series of seven 

 pale primrose-coloured spots, outwardly (owing to the ground-colour at 

 this point being paler than the rest of the wing) defined rather broadly 

 with fuscous, the anterior spot obsolete, a thin blurred line only, the
