In durga one out of six males bad no anastomosis, and similar cases 

 occurred in dirtea and cyanipardus, and apparently in satropaces. It is 

 obvious that this feature is not absolutely constant. I have a specimen 

 of Symphcedra dirtea, female, in which no less than three very conspi- 

 cuous anastomoses occur, the costal vein being united with the first sub- 

 costal branch, the latter with the second, and that with the third. The 

 variation in ProtJwr is mentioned below. Two years ago I made a list 

 of the Malayan species similar to the above, and it exhibited similar 

 irregularities. 



The specimens described below are in Mr. Neumoegen's collection, 

 unless the contrary is stated. 



Family Satteidj;. 



Mycalesis (Sadaeoa) chabaka, Moore, (oculafa). Margherita, only 

 the ocellate form taken. 



Lethe naga, n. sp. PI. X, Fig. 4, 2 . Female, above dark fuscous. 

 Forewing with a broad white oblique band from the costa (near which 

 it is broader and whiter) to the submedian, above which it is suddenly 

 bent downwards, passing close by the end of the cell but not touching 

 it, its inner border distinct, its outer diffused. Hindwing with two pale 

 submarginal lines, the ocelli showing through the wing, especially the 

 white pupil of the fifth. Below uniform light fuscous-brown with a slight 

 bronzy lustre. Forewing, base unmarked e.xcept^ by a very obscure darker 

 line across the cell, the white band as above, two straight pale submar- 

 ginal lines and five perfect subequal ocelli (ringed with pale violet), set 

 in nearly a straight line between the lower median and the lower 

 subcostal branch. Hindwing, with two irregular transverse darker lines 

 placed anusually close together, and enclosing a narrow space obscurely 

 glossed with violet. They originate below the costal vein, the inner 

 crossing into the cell at the origin of the upper discocollular, and 

 continuing parallel with it to the hind margin of the coll halfway 

 between the forkings of the median vein, continued obscurely through 

 the submedian space. The outer line runs in a parabola from the costal 

 vein to the upper median, skirting but not touching the end of the cell, 

 and, crossing the base of the upper median space, disappears above the 

 last ocellus. Ocelli six, all large, perfect, with white puiiila surrounded 

 by black and ochreous and set in a large violet- whitish ring. The first 

 is within the line of the others, and is extremely largo, the next three 

 subequal, the next larger, the sixth geminate, with two separate white 

 pupillcd black spots in a yellow field. Two wavy submarginal pale 

 lines.
