from the base of the wing being much broader, and all the veins 

 being black, instead of only partially black ; from C. nivea alone it 

 may be known by the black costal area of the forewing being 

 discontinuous and not joined to the black apical area, the orange areas 

 at the anal angle of both wings are more extensive and of a deeper 

 shade of colour ; from C. nivalis alone it may be at once distinguished 

 by the strong dilatation on the costa of the forewing of the third 

 common black line from the base of the wings, whereby the white 

 portion of the costal area is greatly reduced ; and by the orange area 

 of the hindwing being much more restricted, and ending on the 

 second median nervule instead of extending to the discoidal nervule. 

 Mr. J. Wray, Junior, Superintendent of the Perak Museum, has 

 kindly sent me three specimens of this pretty and distinct species 

 taken in the Perak Hills at an elevation of between three and four 

 thousand feet above the sea. 



Family LYCLENID^E. 



Genus SIMISKINA, Distant. 



Simislcina, Distant, Entomologist, vol. xix, p. 12 (188G) ; idem, id., Rhop. Malay., 

 p. 450 (1886) ; Massaga, Doherty, Journ. A. S. B., vol. lviii, pt. 2, p. 429 (1889) ; idem, 

 id., 1. c, vol. lx, pt. 2, p. 35 (1891). 



Both sexes with neuration apparently much the same as in Poritia, 

 Moore ; but in the male the hindwing has, in addition to the long tuft 

 of almost colourless hairs which spring from near the middle of the 

 discoidal cell, and which are directed forwards and are covered by the 

 inner margin of the forewing, the second tuft of long black hairs 

 placed in a different position ; in Poritia it springs from near the base 

 of the submedian nervure and lies along the abdominal margin, in 

 Simiskina it arises at the lower end of the cell and lies along the 

 base of the third median nervule. Type, Simiskina fa/gens, Distant, 

 equals Poritia potina, Hewitson. 



The above diagnosis will perhaps suffice for the present to distin- 

 guish the males of this genus from the allied genera. As stated in 

 "The Butterflies of India, Burmah and Ceylon," vol. iii, p. 38, 

 footnote, I am unable to use Mr. Doherty's genus Massaga, of which 

 the type species is potina, Hewitson, (Mr. Doherty in his second paper 

 says that pediada, Hewitson, is the type of his genus Massaga !), as it
