second group which possesses one tuft of hairs only on thehindwing, — 

 the peculiar character of the second subcostal nervule of the fore- 

 win^ being emitted beyond the apex of the discoidal coll. In Myr- 

 tilus it is omit led well before, which appears to be the best character 

 by which it can be distinguished from the subgenus Loom, but 

 possessing no specimen of my <>\vn of the latter lam unable to bleach 

 the win irs and examine the neuration critically so as to give a full

1. MYCALESLS [Myrtilus) MYSTES, n. sp. 



Habitat : Upper Burma. 

 Expaxse : 6 , 2'0 inches. 



Dry- Season Form, PL F, Fig. 1, £. 



Description : Male. Upperside, both wings brown, the extreme 



outer margins paler, bearing two very fine darker brown lines. Cilia 



cinereous. Forewing with three very small (the posterior rather the 



largest) blind black ocelli, one each in the two discoidal and upper 



median interspaces, each surrounded with a fine outer yellow line 



(the two posterior ocelli absent in one specimen) ; a similar large 



ocellus in the same straight line as the other ocelli, and touching 



the lowermost, in the first median interspace, which it slightly 



overlaps, centred with a minute silvery pupil. Hindwing unmarked. 



Underside, both wings ochreous-yellow, the basal darker than the 



outer half; a prominent perfectly straight discal band, not quite 



reaching the costa of the forewing nor the abdominal margin of 



the hindwing, this band is formed of an inner dark brown line, which 



becomes lost in the ground-colour, outwardly sharply defined by a 



whitish line, which also soon becomes lost in the ground-colour ; 



beyond this prominent discal band is a nebulous band of a darker 



shade than the ground, and bearing in the forewing four (in one 



specimen five), and in the hindwing seven, most minute pale blue 



dots, one in each interspace, these being the pupils of obsolete ocelli ; 



a waved submarginal band. 



Described from two male specimens captured by Lieutenant E. Y. 

 Watson at Tilin Yaw, Upper Burma, on the 1st and 19th March, 

 1890.
