HETEROCERA OF SIKHIM AND BHUIAN. 89 
the forewing has all the brown markings which are present in the 
other form replaced by pale buff ones and the apex pure white, the 
hindwing with the sub-basal bands parallel to the medial and postmedial 
ones, not curved. The other form, which is the one figured, is a smaller 
insect (my largest measures 38 mm.) with the forewing distinctly marked 
with reddish-brown and the apex darker brown. The hindwing has tho 
sub-basal band extending down the anal margin towards the medial 
band nearly meeting it, and the postmedial band distinctly curved. The 
antenne of the male are pectinated on one side only, and vein 10 
of the forewing is present. | have nine of the large form and six of 
the small one, all taken at lightin May, June, July, August, and 
September. 
Genus Dysopra, Clemens. 
8il. WD. ignita, W1k. 
Sikhim and Bhutan, 1,600—4,000 feet. Occurs commonly trom 
April to August. The male has a long erectile white fan-tuft arising 
from the origin of the hind tibia and extending the whole length of the 
same ; the lower extremity of the tibia hasa short dark brown tuft, 
Out of 12 specimens in my collection, this is the only male, apparently, 
as none of the others have similar white erectile tufts on the hind tibix. 
812. LD. viridatrix, Wik. | 
Sikhin. I have only seen this in Dr. Pilcher’s collection. It is 
probably rare, (I have two from Sikhim which appear to be quite 
distinct trom Bangalore specimens and agree fairly with the description 
of Mutelia siccifolta, Moore, the type of which is in Dr, Standinger’s 
collection.— A. J. E.) 
$13. D. albifurca, Hmpen, 
Sikkim, Ido not know this. (A small distinct species of which I 
have two only, the types, from Moller’s collection.—/. J. Hi.) 
Genus Gianycus, W1k. 
$14. G. insolstus, Wlk. 
Sikhim and Bhutan. Rare at low elevations. I have twice taker, 
it myself during the day, once at Badamtam and once at Fagoo in 
May. 
815. G. tricolor, Moore, 
Sikhim. I have only one in my collection without date. Nir George 
Hampson and Mr, Elwes regard this as the male of G. insolitus, WI1k.,
