Genus Megisba, Moore. 

 Megisba sikkima, n. sp. 



Male. Differs from M. thwaitesii, on the upperside, in being of 

 a darker violet-brown, and in the absence of the short oblique pos- 

 terior white band on the forewing. Underside similarly marked to 

 M. thwaitesii, except that on the forewing the black spot in middle of 

 the cell is very minute, and there is a spot below the end of tho cell be- 

 tween the middle and lower median veins in addition to the two dots, 

 which are here placed beneath the lower median vein, whereas in M. 

 thwaitesii the two latter dots, when present, are situated between the 

 middle and lower medians. On the hindwing the three transverse sub- 

 basal black spots are comparatively larger, the upper one with two con- 

 tiguous black dots in front ; the cell-spot is prolonged upward to the 

 costal vein and also has some black dots below it, the apical black spot 

 is of an elongated form, and the discal macular band is composed of 

 broader quadrate spots. 



Expanse |- inch. 



Hab. Sikkim. In coll. Indian Museum, Calcutta. 



Pathalia, n. g. 



Closely allied to Megisha : forewing comparatively longer, and less 

 regularly triangular in form : hindwing somewhat narrower, and with a 

 slender tail at end of lower median vein. Venation similar. Second 

 joint of palpi shorter, the third joint longer and more slender. 



Type, P. albidisca. 



Pathalia albidisca, n. sp. 

 Male and female. Upperside dark violet-brown : forewing with a 

 broad medial conical white patch, which extends obliquely from middle 

 of the disc to posterior margin : hindwing with a broad white band cross- 

 ing from the costal edge to near middle of the abdominal margin ; an 

 indistinct marginal row of pale-bordered brown spots. Underside grey- 

 ish-white : forewing with some black spots along the costal edge, a 

 brown streak at end of the cell, a discal transverse row of short oblique 

 slender interrupted lunules, a submarginal sinuous line enclosing a mar- 

 ginal row of indistinct spots : hindwing with a similar brown cell-streak, 

 a discal zigzag series of broader lunules, a sinuous submarginal line 

 enclosing the marginal row of spots, of which the penultimate is 

 large and black ; three equidistant subbasal black spots, a black spot on 

 the abdominal margin above the lower subbasal, and a larger black spot 

 at the apex ; tail in both sexes black, tipped with white. Cilia edged with
