BUTTERFLIES. 179 



540. CTENOPTILrM VASAVA, Mooi'e. 



Rare; found in April and May from 1,000 to 3,000 feet. It 

 occurs also in Central and Eastern China. 



541. Tapena agni, de Niceville. 



A rare species in Sikliim. I have taken it at Singla, at about 

 1,500 feet elevation, in October. 



542. Tapena laxmi, de Niceville. 



Originally described from a female example from the Thaungyin 

 forests in middle Tenasserim, Burma. Major J. F. Malcolm Fawcett 

 obtained a single male example at Singla in May, at about 1,500 feet 

 elevation. 



543. Odontoptilum sura, Moore. 



Common from 1,000 to 3,000 feet from April to October. 



544. Caprona SYRiCHTrius, Felder. 



Mr. Otto Moller obtained a few specimens of this species during 

 the time he lived in the Terai. It does not appear to occur in the hills. 

 Mr. Dudgeon records it from Bhutan at 1,500 feet, in May and July. 



545. Hesperia galea, Fabricius. 



Also obtained by Mr. Otto Moller during his residence in the 

 Terai. Mr. Dudgeon notes its occurrence on the outer spurs at 1,500 

 feet. 



546. Suastus gremius, Fabricius. 



Very common at low elevations throughout the year. The larva 

 feeds on palms, and the female butterfly in Calcutta often enters the 

 houses to lay her eggs on the leaves of the ornamental palms so 

 common in rooms in India.

Very rare in Sikhim, as, indeed, it is everywhere, and is found 

 in the low valleys only during the rains.

Rare in the low valleys from June to October. It has a wide 

 range. I possess specimens from Burmah, the Malay Peninsula, 

 Sumatra, and Java.

Common at low elevations throughout the year.

 warm months.
