278 MR. H. J. ELWES ON BUTTERFLIES FROM [Apr. 2], 



of male dimorphism in which the male and female are different in 

 some localities and resemble each other in others. 



Two names also exist, of which stva is the one most generally used, 

 though doubledayi has priority. It is a curious fact that the extremely 

 rare female sex should have first been sent to England, whilst I 

 have never been able to procure one, and de Niceville had never 

 seen one when the second volvime of his book was published. A 

 specimen in Mr. Crowley's collection, however, is exactly like the 

 plate of ^. doubledayi. 



LiMENITIS AUSTENIA. 



Lebadea austenia, Moore, P. Z. S. 1872, p. 560, t. xxxii. fig. 1. 



Limenitis austenia, Butt. Ind. ii. p. 157. 



Four males and a female of this rare species were taken at Marg- 

 harita in May 1889 by Doherty. According to his observations it is 

 a low-country species. 



EUTHALIA TAOOANA. 



Adolias taooana, Moore, P. Z. S. 1878, p. 831 ; Butt. Ind. ii. 

 p. 197. 



Seems abundant in the Karen Hills at 4000-5000 feet, but only 

 males were sent by Doherty. The female remains undescribed, but 

 probably does not differ materially from the niale. 



There is some variation in the small spots near middle of the hind 

 margin of fore wing above. Normally there are two, but in some 

 specimens one or both are wanting. On the hind wing above the 

 two uppermost spots are present, but of the lower ones one or both 

 are sometimes absent. The ground-colour of the underside is paler 

 than in any other of the group. 



This is nearly allied to E. covfumis of Westwood, from China, a 

 species which I have not been able to examine. 



EUTHALIA NARAYANA. 



E. nafayana, Grose Smith, Rhop. Ex. pt. xv. p. 6, t. ii. 4, 5 (1891). 



I have two males from the Naga Hills differing from each other 

 as well as from E. nara. One of them is the same as the form de- 

 scribed from the Euby Mines as E. narayana, the other is more like 

 E. iva, Moore. I am not able to say without seeing more specimens 

 from different localities whether this should be considered a good 

 species or not. 



EXJTHALIA NARA, var. 



? Adolias nara, Moore, Trans. Ent. Soc. n. s. v. p. 78, t. viii. 

 1 $ (1859). 



E. nara, Butt. Ind. ii. p. 197. 



Two males sent from the Naga Hills by Doherty differ from a pair 

 from Sikkim and others from Khasia in having the spots in the band 

 of fore wing of a greenish rather than a bluish shade. The series of 

 spots on hind wing below are rounder and arranged in a more curved 

 line than in nara.
