Sliillong, but on both wings on the undersicle ; and in another female from Calcutta, on both 

 wings on both sides, there is a small ocellus in the fust median interspace. 



Specimens from the Western Himalayas are the smallest and darkest, usually only the 

 median pair of ocelli is present on the urt'KRSlDE, which in them closely resembles that 

 of y. indtxora ; occasionally one of the upper pair is present, making three in all, and some- 

 times one of the lower pair appears ; on the UNDHRSiDE the ocelli are usually prominent, 

 large, each pair coalescing; the striat'on is darker and the subbasal fascia is indistinct . 

 Specimens from Sikkim are usually rather larger and paler; the UPPERside shows greater 

 variation in the ocellation ; sometimes the upper pair is present and the lower entirely wanting ; 

 sometimes the lower pair is present and the upper wanting. In the plains of Lower and 

 Eastern Bengal, Sylhet and Assam the colouration is paler still ; all six ocelli are frequently 

 present on the uppekside of the hindwin;^, especially in the female-;, but the most common 

 form has five ocelli, the uppermost of the upper pair alone being obsolete ; on the underside 

 the ocelli are smaller, distinct, and all well separated ; frequently they are minute and in 

 some barely traceable. In our specimens from Shillong this feature is most developed ; in 

 scarcely a single specimen of the spring brood are the ocelli prominent, and in many they are 

 for the most part obsolete on the underside, while on the upperside they are darker and 

 usually with only the median pair of ocelli present on the hindwing ; these latter are almost 

 indistinguishable from Y. indecota ; the July brood closely resembles specimens from Sikkim. 

 These two distinct variations are also shewn in specimens taken by Dr. Anderson in the Mergui 

 archipelago during the cold weather. Specimens from the Western Ghats and hills of South 

 India are intermediate between the Sikkim and Shillong forms ; the ocelli are usually small or 

 minute but distinct ; specimens from Akyab correspond with those from Sikkim ; but in Tenas- 

 serim the greatest variation is found in depth of colouration, in ocellation, and above all in size. 

 A MALE from the Meplay valley measures two inches in expanse ; the upperside is silky mouse- 

 brown, the nebulous band distinct on the hindwing, barely discernible on the forewing, the apical 

 pair of ocelli are prominent on the hindwing, while the subanal pair is represented by a single 

 minute blind ocellus ; the underside is very pale buff, the striation is pale and fine, and the 

 fasciae are prominent and dark, especially on the forewing ; the ocelli of the hindwing are 

 distinct but minute and well separated ; and a female from the lower Thoungyeen forests is 

 dark brown, the nebulous fascise prominent on both wings, the median pair of ocelli on the 

 hindwing very large and prominent, with a single apical and a single subanal ocellus small 

 and less distinct ; on the underside the striation is bold and dark, the fasciae prominent, 

 the ocelli of the hindwing very large, each pair with the irides completely coalesced and 

 encircled by a single dark outer line, the subanal pair being geminated. 



Y. Philomela is found in the Western Himalayas in July ; in Sikkim from July to December ; 

 in Shillong in March, April and May, and again in July ; in Lower and Eastern Bengal it is 

 very common from May to July, and again in November, and probably throughout the year ; 

 in Cachar Mr. Wood-Mason took it in profusion from April to October ; from Arakan, Pegu, 

 Tenasserim, and the Mergui archipelago, we have specimens taken in all months from 

 October to March ; specimens from Khandalla and the Coessi Ghat in the South Konkan 

 were taken by Mr. G. Vidal at the end of March ; and from Travancore by Mr. Harold 

 Fergusson at 2,000 feet elevation in March and April.
