NYMPIIALID.E. SATYRIN.-E. YPTIIIMA. 219 



Description : " Upperside dark Ijiown, wilh an indistinct hipupiiled ocellus on the 

 fornviug, and two subanal ocelli on the hinthviiig. Underside grey, numerously covered 

 with dark brown narrow striae, and crossed with three brown fascice, the subbasal one being 

 indistinct. Fornoing with a bright oval ocellus bipupilled with silver. llind'ving wilh 

 seven small pro.Tiinent silver-pupilled ocelli, the upper third minute, the two anal geminated." 

 [^Moovf, 1. c.) 



Y. avanta closely resembles Y. siiigala on the upperside, but has a sexual patch on the 

 forewing of the male, which Y. siugaUi lacks. On the underside the ocellation ,00 is some- 

 what similar, but Y. singula almost always lacks the transverse dark fascire, which in Y. avanta 

 are conspicuous. From Y. iiidecora it differs on the upperside in having the ocelli of the 

 hindwing blind, and that of the forewing small, very indistinct, sometimes quite obsolete ; and 

 on the underside in having the ocelli distinct (though varying in size in different specimens), 

 and always prominently pupilled with silver. From Y. philomela it is distinguished by the 

 four lower ocelli on the underside of the hindwing being arranged in linear order, not in pairs 

 in echelon. 



The specimen described originally by Mr. Moore with, on the underside of the hindwing, 

 "seven ocelli, the upper third minute," was evidently an aberrant form, for among all the 

 numerous specimens we have seen, the seven ocelli appear in only a single one ; all the lest 

 have the minute upper third ocellus entirely wanting. Similar aberrations occur in Y, 

 philomela, in which specimens with seven ocelli are even less uncommon. The FEM.4LE 

 differs from the male only in having the wings rather broader ; on the upperside no sexual 

 patch on the forewing, and the ocellus of the forewing more prominent and distinctly circled 

 with yellow, and on the underside in the single typical specimen we have seen the ocelli 

 are larger with wider yellow irides, the striation is somewhat coarser, and the subbasal fascia 

 is less distinct. The size of the ocelli in the male also differs widely ; in some they are 

 minute with very narrow irides, in others large, with wide yellow irides. 



K avanta is found in the Western Himalayas from April to August, being common in 

 Kulu and extending to Kashmir on the west, and to Sikkim on the east. 



A variety of this species has been taken in Tenasserim by Captain C. T, Bingham, which 

 is considerably larger, 17 inches in expanse; the male is on the upperside slightly more 

 fuliginous in colour, and the ocellus of the forewing is represented by a single indistinct dark 

 spot ; on the underside it is slightly paler, and the ocelli of the hindzving ^x& very minute. 

 The FEMA'.E is paler on the upperside, with the ocellus of the forewing prominent, bipupilled, 

 and with distinct yellow iris ; and the two on the hindwing each with a single pupil ; there is 

 also on both wings a distinct indication of the broad nebulous submarginal band defined at both 

 edges with darker lines which is so prominent in females of Y. philomela. The underside 

 is as in the male, but still paler. The male was taken in the lower Thoungyeen forests in 

 May, and the female in the Donat Range in January. 



The figure (named erroneously Y, ordinata on the plate) shows the upper and undersides 

 of a male specimen from Kulu, in the Indian Museum, Calcutta. In it the ocellus of the 

 upperside of the forewing is rather more distinct than is usual, and the pupils of the ocelli 

 of the underside of the hindwing, which are silvery and prominent, have unfortunately not 

 come out in the plate ; these ocelli are also larger in this specimen than in typical ones, though 

 we have other examples with the ocelli twice as large.
