to Halpe lioniolea, Hewitson (H. sihkima, Moore), from which it may 

 instantly be known by the upperside being pi^actically spotless, and the 

 underside but very faintly instead of prominently marked. It has also 

 no discal stigma on the upperside of the forewing in the male. 



Described from numerous specimens in Dr. Martin's and my collec- 

 tions taken at Bekantschan in August and September, and in the Battak 

 Mountains, in August, both in N.-B. Sumatra. 



46. Kerana fulgur, n. sp., Plate I, Fig, 6, ? , 



Habitat : Selesseh, N.-E. Sumatra. 



ExPAifSE: (J, 9 , 1*7 inches. 



Description : Female. Upperside, hoth vnngs dark shining purplish- 

 fuscous. Cilia concoloroLis. Foreioing with a broad discal orange fascia, 

 anteriorly not quite reaching the costa, posteriorly ending on the sub- 

 median nervure. Hindioing immaculate. Underside, loth ivings with 

 the ground-colour duller than on the upperside. Forewing with the 

 apex faintly dusted with ochreous scales ; the discal orange band more 

 extensive than on. the upperside, reaching the inner margin, where it 

 is much paler, the edges of the band more irregular. Einchoing un- 

 marked, except by the following steel-blue spots, which can be seen in 

 all lights, but are more prominent in some lights than in others : — An 

 elongated one closing the discoidal cell, one in the first median inter- 

 space about its middle, and three in the submedian interspace at about 

 equal distances apart. A7itenn(B black above, the club beneath ochreous. 

 Palpi black above, beneath chrome-yellow. Eyes encircled by a band 

 of chrome-yellow. Head, thorax, and abdomen above fuscous ; abdomen 

 beneath with six ochreous lines. 



Nearest to K. gemmifer, Butler,* (which also occurs in N.-E. 

 Sumatra, as well as in Perak and Malacca, I have taken it on the Penang 

 Hill at 2,200 feet elevation above the sea, in November), from the same 

 sex of which it differs in being larger, the ground-colour of the upperside 

 darker, the gem-like spots of the underside quite different, and the 

 abdomen beneath striped with ochreous instead of being concolorous. 

 The "gems" of K. gemmifer have never been described in detail. 

 Mr. Butler refers to them thus : — *' End of cell and apical area of pri- 

 maries and disk of secondaries [on the underside] spotted, in certain 

 lights, with shining amethyst-coloured spots " in both sexes. They are 

 thus disposed : — Foreiving with an elongated one placed on the fold in 

 the middle of the discoidal cell just anterior to the inner edge of the 

 discal orange fascia ; three subapical ones placed one above the other,
