the Sikkini terai that the species begins to vary, acquiring a more or 

 less well-marked blue gloss on the upperside of the wings, and some 

 discal spots on the fore wing, which leads us to the typical form of the 

 species. 



Typical form E. hlugii, Moore. 



Habitat : Maldah, lower slopes of the Sikkim Hills, Bhutan, Assam, 

 Arakan, Pegu. 



Expanse : <7, 3-5 to 4-0; 9 , 3-0 to 4-2 inches. 



Description : Male. Upperside. [Of all the species of Euplcea 

 known to me this is the most variable. Following the order of the 

 Pademma group here adopted, the varieties which most nearly resemble 

 E. hollari are first described, while the true E. hlugii, which is the most 

 divergent form in one direction, is next described, and lastly those 

 variations are described which lead up to the geographical race E. erich- 

 sonii, Felder, which ends the series.] A specimen from Sikkim in my 

 collection agrees absolutely with typical E. sinhala, Moore, from Ceylon, 

 except that the base of the fore wing on the upperside in some lights is 

 slightly blue-glossed ; other Sikkim specimens I possess have the sub- 

 marginal and marginal spots to both wings rather smaller than in typi- 

 cal E. hollari, while others again are normal in this respect, both the 

 latter forms being slightly blue-glossed. In the next gradation the dark 

 basal area of the forewing on the upperside is less well marked, and ex- 

 tends more towards the outer margin, while the first discal spots divided 

 by the lower discoidal nervule have appeared ; these varieties occurring 

 in Sikkim, Assam, and Arakan, but always sparingly. In the next group, 

 which includes the typical E. hlugii, it is quite impossible to describe 

 within reasonable limits all the variations which occur. The dark basal 

 area now gradually disappears altogether, the blue-glossing becomes 

 more and more intense till it reaches its maximum, the spots of the 

 wings are infinitely variable — in some there are the two marginal series 

 only, in some one or both these series are obsolete on the hindwing, in 

 some the marginal series is confined in the forewing to a few at the anal 

 angle, or are absent altogether, while the submarginal series are some- 

 times reduced from the full number of nine to four mere dots towards 

 the apex ; the discal spots vary from a complete series of four to none at 

 all ; while in some specimens there is a large spot at the end of the 

 discoidal cell, in others a small spot, and in others again no spot at all ; 

 the colour of the spots also varies, some are pure white, others strongly 

 glossed with blue ; there is sometimes a costal spot at the base of the 

 first and second subcostal nervules, this being frequently absent. On 

 the hindwing some specimens are richly blue-glossed on the disc, while
