450 MR. L. DE NICEVILLE ON NEW OR [May 3, 



distinguished from the same sex of L. europa by its more tawny 

 coloration on the upperside, the discal band bright ochreous instead 

 of white, with its outer edge more irregular, and by the underside 

 of the hind wing having four well-formed perfect ocelli ; \nL. europa 

 the black middle portion of all the ocelli except the upper one is 

 entirely disintegrated and broken up into black dots. 



Mr. E. H. Man obtained a single specimen of this interesting 

 species on Little Nicobar. 



Lethe gulnihal, n. sp. (Plate XXXIX. fig. 7, 6 •) 



Hah. Bhutan. 



Expanse. S 2-45 inches. 



Male. Upperside: both wings dark brown, with a distinct rich 

 vinous gloss. Fore wing unmarked, except that the narrow discal 

 band of the underside shows through paler on the upperside, the 

 wing being somewhat paler beyond. Hind wing with the four middle 

 ocelli of the underside showing through indistinctly. Underside : 

 both wings dull brown without any vinous gloss. Fore wing with a 

 short narrow ferruginous line across the middle of the cell, another 

 similar one towards its end, the lower discocellular nervule marked 

 with ferruginous ; a slightly outwardly-curved discal line from the 

 subcostal nervure to just below the first median nervule, beyond 

 which are four somewhat obscure small perfect ocelli placed between 

 the nervules from the upper discoidal to the first median nervule ; 

 a fine dark brown marginal line bordered on either side with paler 

 and an anteciliary similar dark line. Hind wing with a pair of 

 narrow ferruginous lines across the disk from the costal to the sub- 

 median nervure, the outer one very irregular ; the lower disco- 

 cellular nervule marked with ferruginous ; a series of six small 

 distinct perfect ocelh composed of a black centre with a white pupil, 

 a yellow, a black, and lastly a pale violet ring ; the upper ocellus out 

 of line, placed furthest from the margin and the largest, the three 

 lollowing subequal, the fifth a little larger, but not so large as the 

 first, the sixth the smallest of all and geminate ; two fine dark 

 marginal lines enclosing a fine ochreous line, the inner one. inwardly 

 defined with pale lunules. 



The secondary sexual characters (" male marks ") of L. gulnihal 

 are very peculiar and interesting. On the upperside of the hind 

 wing it possesses the tuft of long black hair which is found in L. 

 scanda, L. bhairava, L. latiaris, L. minerva, L. siha/a, and L. dyn- 

 sate ; in addition it has a large oval patch of deep black lustrous 

 scales, which is bounded above by the first subcostal nervule, partially 

 inwardly and beneath by that portion of the subcostal nervure 

 between the bases of the first subcostal and discoidal nervules, the 

 patch not nearly reaching the margin (this feature occurs in L. 

 bhairava in a somewhat modified form); lastly, the inner margin 

 of the fore wing is deeply outwardly bowed, which is a unique 

 feature, the bowed portion beneath the submedian nervure clothed 

 with difi'erently formed and modified scales to those on the rest 

 of the wing, this portion of the wing being clearly defined on
