1887.] LITTLE-KNOWN BUTTERFLIES FROM INDIA. 463 



band ; all these spots composed of a pale centre, then a narrow black 

 line, outwardly defined with a pale line ; beyond the discal macular 

 band is a fuscous diffused fascia, outwardly defined from the abdo- 

 minal margin to the second median nervule by a pale luuular line ; 

 in the next two interspaces the fuscous fascia almost reaches the 

 margin and encloses two of the pale lunules ; a series of black mar- 

 ginal lunules between the veins ; a fine anteciliary black line ; the 

 very small anal lobe with a deep black round spot, with a few obso- 

 lete silvery scales crowning it ; a few also in the two next interspaces. 

 Cilia of the colour of the ground throughout. 



Apparc'itly nearest to the Amblypodia ocrida of Hewitson', from 

 which it differs in the colour of tlie upperside, that species being 

 " silvery cerulean blue ; " there also appears to be some difference 

 in the details of the markings of the underside. 



I have named this species after Mr. R. Wimberley, who captured 

 two specimens of this beautiful species in the South Andamans, 

 together vvitli several other species which had not been previously 

 obtained on those islands, not the least interesting of which is a 

 female specimen of the Veudorix smilis of Hewitson, described 

 ambiguously from " East India." 



IsoTETNON FLAVALUM, n. sp. (Plate XL. fig. 10, (S .) 



Hub. Sikkim. 



Expanse. ^ \-2 inch. 



Male. Upperside: both wings dark brown. Fore wing with 

 three small subapical increasing spots, the upper one minute; a 

 small quadrate spot at the lower outer end of the cell, an elongated 

 one at the base of the second median interspace, a much larger 

 quadrate one below it and })laced nearer the base of the wing in the 

 first median interspace, all semitransparent diaphanous ochreous. 

 Bind wing with the middle of the disk clothed with long greenish- 

 ochreous hairs. Cilia cinereous throughout. Underside : fore 

 wing also dark brown, the spots as above, the costa narrowly and 

 the apex widely (but not reaching the anal angle or the outer mar- 

 gin) yellow, //njrfw/w^ yellow throughout except the outer margin, 

 which is increasingly dark brown, widening to the anal angle ; a 

 conspicuous thougli small black spot on the discoidal cell, three 

 smf 11 darii-brown ring-spots placed very close together below it, and 

 a fourth minute black spot well separated from the others towards 

 the apex. No secondary male sexual characters. Head and bodg 

 above dark brown, below with legs yellow. AntenncB black, the 

 club tipped beneath with white. 



This pretty and very distinct little species is nearest allied to Iso- 

 teinon safwa, inihi -, but is abundantly distinct ; the underside h.is 

 no purple washing, and on the hind wing the yellow coloration 

 occupies nearly the entire surface ; in /. satwa it is confined to the 

 anterior half of the wing.
