SOME UNDESCRlBED RHOPALOCERA FROM SIAM. 173 



the wings more rounded, the submarginal baud of forewing not 

 obscurel in areas la and 2. Underside. — Pale markings somewhat 

 more developed, the very large ocellus in area 4 of hindwing partial- 

 ly fused with that in area 2. Otherwise as in the male. 



Length of forewing. — 6 20 mm; $ 21 mm.

 of Utaradit, N. E. Siam, Jan. 1920. 



This species is separable at onee from R. crisilda Hewitson, 

 R. critolau? and R. cristata de Niceville, its nearest allies, by the 

 number of the ocelli on the underside of the hindwing. In crisilda 

 there are invariably seven, those in areas 3, 4 and 5 being fused ; in 

 the other two species there are six, that in area 3 being absent, and 

 those in areas 4 and 5 fused. In criti is there are only five. The 

 broad dark discal band of hindwing which bears the ocelli is much 

 broader in critias than in either of de Niceville's species, and is 

 bordered externally by a muc'i better defined white band than in 

 crisilda.

5. Stichophthalma cambodia editha, ssp. nov. 



(Plate IV.. fig. 5.) 



d $. Upperside both wings. — Similar to S- c. cambodia 

 Hewitson, but with the discal pale area rather more extensive, 

 brighter and clearer, less sprinkle! with brown scaling; the V- 

 shaped marks in the discal series narrower, the tips not recurved, 

 and each mark with a small conical median projection basad, 

 making the marks more dagger-like in shape ; the antemarginal 

 smoky -brown lunules reduced in size and almost surrounded by the 

 pale discal colouration, except towards apex of forewing. In the 

 female of editha the large proximal extension of the V-spot in area 

 6 (typical of cambodia, the Type of which is a female) is partially 

 suffused with bluish white scales, and has a white spot in the centre, 

 whilst in the male it is absent altogether. 



Underside, both wings. — Considerably paler than in typical 

 cambodia. In the male the forewing has the basal half reddish 

 grey-brown, bordered by a narrow band of white, the latter broader
