The type of the genus is L. megmra^ Linnaeus, which belongs to a 

 different group to L. mrnra and its allies. Mr. Moore in Lep. Ind., 

 vol. ii, p. 5, in describing the genus Lasiommata, notes that it has a 

 '^ glandular fascia ■" in the male, but in describing L, mcerula, Felder, 

 he says the '' forewing does not possess a glandular fascia." As a 

 rule, Mr. Moore gives the presence or absence of secondary sexual 

 characters generic rank ; but in this instance he has, I think, done well 

 in not doing so, as the species with and without this character are 

 obviously generically very closely allied. 



The type specimens figured are from the Gonas Pass. 



4. YPTHIMA lARBA, n. sp., PI. R, Figs. 7, 3 ; 8, ^. 



Habitat : Manipur ; N.-E. Sumatra. 



Expanse : $,1'Q ; $, 1-8 inches. 



Desckiption : Male. Upperside, both wings hair-brown, the basal 

 half darker ; a darker marginal band about 2 mm. wide ; cilia 

 cinereous. Forewing with the usual oval black subapical ocellus out- 

 wardly defined by an orange ring, and bipupilled with silver. Hind- 

 wing with five ocelli, the anterior one in the upper subcostal interspace 

 and the two geminated posterior ones in the submedian interspace 

 minute, the pair in the median interspaces large, oval, black, with a 

 well-defined narrow outer orange ring and a single silvery pupil ; an 

 anteciliary pale thread. Undeeside, both wings whitish, fairly evenly 

 throughout covered with rather coarse ochreous-brown striolae. Fore" 

 wing with two rather obscure straight discal dark brown fasciae, neither 

 reaching the costa nor the inner margin, the inner one half as wide as 

 the outer i the ocellus as on the upperside, but the orange iris wider and 

 better defined. Hindiving with the outer of the two discal bands of 

 the forewing present but very faint ; five ocelli as above, but the 

 anterior and two posterior ones much larger, the ones in the median 

 interspaces the same size as above ; all the ocelli have an outer narrow 

 dark brown ring. Female. Uppeeside, both wings differ from the 

 male in being paler. Forewing with the discal area from the outer 

 discal band of the underside to the marginal band paler than the rest 

 of the wing and striated faintly with dark brown. Hindwing also has 

 a broad discal similar area. Otherwise as in the male,
