CEL^NORBHINM. 41 



Underside. Forewing somewhat jjaler tliaii the upperside, markiDgs simihir. Hind- 

 wing usually much darker grey, sometimes l»lue-grey, a small hlack dot at the end of 

 the cell, in some examples a complete discal irregular series of black spots, but very 

 variable in its prominence, and in many examples no better indicated than it is in the 

 male ; head and body above concolorous with the wings ; palpi and body Ijelow con- 

 colorous with the hindwing. 



Expanse of wings, $ % 1/^ to 2yV inches. 



Habitat. — Central and Southern India, Burma, Andamans, Nicobars, Malay 

 Peninsula and Archiix-lago. 



Distribution.— Recorded from the Karen Hills, Chin Hills, Tavoy, Calcutta, 

 Cachar, Bombay, the Central Provinces, Khasia Hills and many other parts ; we have 

 received many examples from the Khasia Hills ; we took it in several places in the 

 Bombay District, and at Mhow, and have it from Pvangoon, Bassein, the Atarau Valley, 

 the Andamans, Orissa and Annam ; it is a common and very variable species every- 

 where, except in the northern parts of India ; and it does not appear to occur in 

 Ceylon. After a careful study of numerous examples from different localities, we have 

 come to the conclusion that it is impossible to separate atticus = ravi from khasiana 

 ravina, and very much doubt tlie distinctness of epichdrmus, Friihstorfer, but not 

 having seen any examples from Siam, we leave it in the list of " Allied species ; ' there 

 does not appear to be, on examination, a character in either ravi or khasiana, or in the 

 descrijitions given by JMoore to each, that cannot be found common to both from all 

 kinds of localities, and Elwes does not say that he has found any difference in the 

 genitalia. The semi-hyaline spots vary much in size, and the underside of the hindwing 

 is in all shades of colour from fuliginous-brown to grey, and the discal series of blackish 

 spots varies much in size and in number. Aurivillius, who examined the Fabrician 

 types in the Museum at Copenhagen, says * as to Hesperia atticus, Fabricius, " Der 

 Typus stellt die Yarietat von Tagiades ravi Moore dar, bei der dei Uuterseite der 

 Hinterfliigel nicht weiss, sondern duukel braungrau ist. Der Besehreibuug passt jedoch 

 nicht. Es l)leibt darum zweifelhaft, ob Fabricius ravi Moore oder eine andere Art vor 

 sich gehabt hat." 



Considering the very great variability of the species there can be no doubt that 

 upon the above evidence Moore's ravi must become a synonym of atticus, Fabricius. 

 We give figures of the two extreme forms of both sexes, Nos. 1 and ll), a male from 

 the Khasia Hdls, No. la and Ic, its corresponding female from Rangoon, No. Id and 

 If, a male from the Khasia Hills, and No. le and Ig, a corresponding female from the 

 Andamans.
