its middle, enclosing a paler space ; a discal irregular dark band, 

 with its inner edge diffused, its outer edge sharply defined, its 

 direction from the costa to tlie first median nervule straight, then 

 directed inwardly to the submedian nervule, the ground beyond this 

 band paler than the rest of the wing ; the submarginal subapical 

 dots as above but violet-wliite ; a very fine violet-white line, then a 

 broad ochreous line, then a fine dark line on the margin. Hind wing 

 with an oval ring-spot at the base of the costal interspace, a band in 

 continuation across the cell, another band beyond from the costal to 

 the median nervure towards the end of the cell, dark brown, out- 

 wardly pale ochreous, and very straight ; a short irregular band 

 from just before the base of the first median nervule towards the 

 abdominal margin ; a highly irregular discal band, its outer edge 

 sharply defined, its inner edge diffused ; beyond which is a series of 

 six ocelli, composed of a black centre with a violet-white pupil, an 

 ochreous, a dark brown, and a violet ring, the latter ring widest out- 

 wardly, the sixth ocellus at tlie anal angle geminated ; a fine marginal 

 violet line, expanding into lunules at the anal angle, two fine dark 

 lines beyond the violet line enclosing an ochreous broad line. 



Lethe tristiymata is nearest to L. nicetas, Hewitson ; but the male 

 is at once distinguished from that species in possessing a very 

 conspicuous " male mark " on the upperside of the fore wing just 

 beyond the cell, which is composed of more or less wedge-shaped 

 clum]js of large black scales, placed one below the third median 

 iiervide, one on each side of the second and first median nervules, and 

 one above the submedian nervure, these marks sometimes coalescing 

 and forming a continuous band divided only by the veins. 



Expanse 2'3 inches. 



ZOPHOESSA MOLLERI, D. Sp. 



This species is very nearly allied to Z. jalaurida, de Nicev., but 

 differs constantly in the following particulars. The tawny bands and 

 markings of the upperside are paler and less defined. Beneath, the 

 ocelli of the fore wing are absent, the ground-colour is paler, the 

 silvery bands are straighter and broader, and in the outer one, which 

 is broadest, the discocellular nervule which it encloses is distinctly 

 marked by a brown streak in the silver band, which is free and not 

 connected with the brown band next the silver as in Z. jalaurida. I 

 found this species mixed with jalaurida, but not so abundant or 

 reaching so high an elevation, on the Singalelah range, and did not 

 at first recognize its distinctions, which Moller afterwards noticed. 

 After comparing 12 fresh specimens with 10 perfectly fresh males 

 and 6 females of Z. jalaurida taken with it, and one from the Jalauri 

 Pass, I have no hesitation in saying that it is a perfectly distinct 

 species, and have much pleasure in naming it after Mr. iVIoller. The 

 two sexes ai"e nearly alike, but the females, of which I only took 

 two, are a trifle larger and paler than the males.
