taken in May, June, July and October. The males vary greatly in 

 size, the smallest measures *95 of an inch, the largest 1*35 inches. 

 The markings and coloration of the underside remind one of those of 

 Lampides, which is considered to be a protected genus, and may perhaps 

 to some extent account for the scarceness of specimens of R. delioohus 

 in collections, as they are passed over for the common species of 

 Lampides which they may mimick. 



500. Rapala rh(ecus, de Niceville. 



R. rhrxcus, de Niceville, Journ. Bomb. Nat. Hist. Soc, vol. ix, p. 319, n. 35, pi. P, 

 fig. 47, male (1895) ; idem, id., I.e., vol. x, p. , n. 27, pi. T, fig. 40, female (1896). 



Taken at Bekantschan and in the Battak mountains, where this 

 fine species is fairly common in May and July, rarer in March, April 

 and October. The female on* the upperside is somewhat marked with 

 red on both wings, on the inner margin of the forewing, and near the 

 anal angle of the hindwing, an unusual feature in this genus. 



501. Rapala schistacea, Moore. 



A few specimens only from Selesseh taken in May and June. 



502. Rapala scintilla, de Niceville. 



Hitherto known from Sikhim only. Its occurrence so far south 

 is very interesting. It is quite a distinct species, which can always 

 be discriminated in both sexes by the peculiar coloration of the under- 

 side alone, though as regards the male the restriction of the blue 

 gloss to the upperside of the hindwing best distinguishes that sex. 

 In Sumatra it is commoner than R. schistacea, Moore, and is found 

 from Selesseh to Bekantschan from March to June. 



503. Rapala oeseis, Hewitson. 



Hewitson. Grose Smith. Kirby. Distant. Originally described 

 from Sumatra, certainly the commonest species of the genus, and 

 found from Bindjei to Soengei Batoe throughout the year. 



504. *Rapala chozeba, Hewitson. 



Hewitson. Grose Smith as var. chozeba. Hagen as Deudoryx [sic] 

 chozeba. Kirby. Originally described from Sumatra. We have failed 

 to recognise it. It is very near to R. orseis, Hewitson. 



505. Rapala nissa, Kollar. 



Only two females taken in the Battak mountains in October, 1893.
