6 J8. # CeljENORRHINUS ladana, Butler. 
Astictopterus ladana , Elwes, Proc. Zool. Soc. Lond., 1892, p. 662, pi. xliii, fig. 4, 
male. 
Grose Smith. I have never seen this species. 
619. Cel&norrhinus leucocera, Kollar. 
Throughout the year, but most plentifully in March, and fairly 
common from Bekantschan to the Central PJateau, never at lower 
elevations. 
620. CeLjENORRHinus Simula, Hewitson. 
Pterygospidea Simula, Hewitson, Ann. and Mag. of Hat. Hist., fourth series, 
vol. xx, p. 321 (1877). 
Hewitson. Grose Smith. Originally described from Sumatra. 
Occurs at the same time, and in the same localities, as C. leucocera , 
Kollar, but is somewhat rarer. 
621. Celaenorrhinus Asmara, Butler. 
Hagen as acmara [sic]. Yery rare, only two specimens obtained 
from the mountains in October. 
622. Celaenorrhinus aurivittata, Moore. 
Hagen. Common throughout the year from Selesseh to Bekant¬ 
schan ; very plentiful near Namoe Oekor. It is very quick flying, and 
always settles on the undersides of leaves near the ground. 
623. Coladenia dan, Fabricius. 
Snellen. Hagen. Staudinger. Common over the whole of our 
area, and flies throughout the year, often frequenting the same flowers 
as Zemeros albipunctata , Butler, and Z. emesoides, Felder, on which it 
settles in nearly the same manner, so that it is only when the insect is 
in the net that its identity can often be determined. 
624. Daimio dirae, de Niceville. 
' D. dirge, de Niceville, Journ. Bomb. Nat. Hist. Soc., vol. x, p. , n. 37, pi. Q, 
fig. 49, male (1896). 
Rare, five specimens only, from May to July near Selesseh and on 
the outer hills near Namoe Oekor. 
625. Satarupa gopala, Moore. 
Only at higher elevations south of Bekantschan rarely throughout 
the year. It is an interesting fact that this butterfly, which has only 
hitherto been recorded from Sikliim, Assam, and Burma, should occur 
as far south as Sumatra.
