234 NYMPHALID^. SATYRIN.^. RAGADIA. 



227. YptMma taTsella, Marshall, n. sp. 



Habitat : Wynaad, South India. 



Expanse : <?, 1*15 inches. 



Description : Male : Upperside brown, uniform in shade. Foreiving with a not 

 very prominent hipupilled ocellus. Hhuhving with two submarginal ocelli between the median 

 nervules, the upper one minute. Underside paler brown, with greyish undulations most 

 numerous on the hindwing. /^)/-^w«o- with the ocellus as usual. Hindwing with six ocelli 

 placed in pairs in echelon, the apical pair geminate on the lower subcostal nervule, the upper 

 minute, the median pair complete but touching on the median interspaces, the anal pair ge- 

 minate, the lower being extremely minute, the outer margin somewhat darker, but no trace 

 otherwise of fascize on the underside. No sexual patch on forewing on upperside. 



At first sight Y. tabella appears to be only a dwarf specimen of Y. sakra, but the grayer 

 tone of the striation of the underside, the subanal ocellus being geminated not bipupilled, 

 the very small size, and also the locality from whence it comes, mark it as distinct. It is dis- 

 tinguished from Y. Philomela and its allies by the absence of the sexual mark in the male. No- 

 thing approaching Y. sakra is known to occur south of the Khasi hills in the vast interme- 

 diate country between them, and the Wynaad where Y. tabella appears. 



Genus 21.— EAGADIA, Westwood. (Plate XV.) 



Neonynipha, subgenus Ragadia, Westwood, Gen. D. L., vol. ii, p. 376 (1851). 

 "Distinguished from iVc'tf«j'W/'^<z [an American genus] by the very singular arrangement 

 of the veins of the wings, especially of the hindwing ; the lower disco-cellular nervule being 

 placed almost at the base of the wing, and furnished with an elongated pouch in the males. 

 The costal nervure of the forewing is alone swollen at the base." (Westwood, 1. c.) 



Body slender. Head wide, antennce slender, distinctly articulated, with a slender gra- 

 dually formed club. Eyes almost naked. Palpi moderately long, densely clothed in front 

 with rather long bristly hairs, not tufted at the back, terminal joint slender. Forewing 

 somewliat elongate ; casta slightly curved ; outer margin oblique, slightly convex ; costal nervure 

 alone swollen at the base, the remaining neivures simple ; disco-cellular nervules concave, the 

 upper very short, the middle long, the lower longer still, and joining the median nervure at an 

 acute angle some distance beyond the origin of its second branch ; subcostal nervure \;\\\\ its 

 branches free and short, \}[\.q. second originating beyond the cell, as in Yptkima ; discoidal nervules 

 from the junctions of the disco-cellulars, the upper one originating very close to the subcostal 

 nervure. Hindwing rounded ; pracostal nervure very short, curved outwardly ; costal nervure 

 curved at base, and joining the costal margin at about one-half its length. Subcostal n&x\\xxt 

 almost straight ; discoidal cell very short and acute ; discoidal nervule curved at its base and 

 appearing to originate from the subcostal nervule below ; the lower disco-cellular appearing to 

 originate from the subcostal at some distance nearer the base, then acutely angled outwardly and 

 joining the median nervure at a very acute angle some distance before the origin of its first 

 branch ; along its free part closing the cell it is simple in the female, but in the male it is 

 developed along its underside into a narrow glandular pouch, and on the upperside is furnished 

 with a small tuft of fine long hairs which lie along it. Forele&s of the female slender, 

 destitute of hairs, the joints of the tarsus very short, dilated, distinct, each furnished with a 

 single spine on the lower side, and appearing as a clubbed termination to the slender leg : of 

 the male wanting in our only specimen. 



Ragadia is a very remarkable and aberrant genus ; and its affinities are difficult to determine ; 

 according to the characters taken in the key to the genera it should have come in the first 

 group, as the apex of the cell in the hindwing is distinctly not beyond the origin of the second 

 median nervule, nor are the eyes entirely destitute of hairs ; of the first group it has most 

 affinity with Mycalesis, especially in the dilation of the disco-cellular nervule in the hindwing 

 and the tuft of hairs along it in the male, but its nearest ally is evidently Ypthima, with which 

 it corresponds in the arrangement of the subcostal nervules of the forewing ; in the brilliant
