HETEROCERA OF SIKHIM AND BHUTAN. 9 



Darjeeling, perhaps some of them belong to the following, but only a 

 specialist can name such insects with any certainty.—//. J. E.) 

 N. melanoia, Hmpsn. 

 Sikhim and Bhutan. This species is so like the last that I do not 

 think it is really separable. N, argentalis has the markings more 

 clouded and is larger, but the same markings can be traced in N. mela- 

 nota better defined. The postinedial line being punotiform is scarcely, I 

 thmk, sufficiently characteristic. It is found from l^iO feet up to 7000 

 feet in Sikhim, and I have oue specimen from Bhutan from 2500 feet. 

 July to October are the months during which I have taken it. (Quite 

 distinct ; much smaller ; antennae with the branches shorter and paler 

 than N. argentalis, patagia wholly white. — G. F. H. ) 

 1533. N. distnhuta, Wlk. 

 Sikhim and Bhutan, 1800 — 3000 feet. This is a common species at 

 light at Fagoo and is to be taken at lis^ht from May to September. I 

 have a specimen from Kangra also, which diSers from Sikhim speci- 

 mens in having the forewing broader and shorter. 

 N. tristicta, Hmpsn. 

 Sikhim and Bhutan, 6400 feet. This species is apparently very 

 nearly allied to N. distributa and N. microphasma. I have one 

 specimen taken in September at Rissoom and another, which I am not 

 quite sure belongs here, taken in June. 



1534 h. A', microphasma, Butl. (Plate II, Fig. 26, ) 

 Bhutan, 2500 feet. I have taken this at light in July and August. 



1520 a. N. latlcinda, Hmpsn. ( Plate II, Fig. 28. ) 

 Bhutan. The type which is now in the British Museum is the only 

 specimen I have seen. 



1534 r/. N. nigrisparsa, Rm^^n. (Plate II, FiG. 21. ) 

 Sikhim and Bhutan. Five specimens have been taken by me at light 

 at from 1800 — 3000 feet, in May, August, October and November. 

 Genus Pcecilonola, Hmpsn. 

 1541 b. P. seminigra, Hmpsn. ( Plate II, Fig. 30. ) 

 Sikhim, 1800 feet ; Bhutan, 2500 feet. I have eight specimens, six 

 of which were taken by me at light at Fagoo and one at Punkabaree. 

 Three of my specimens are males and differ only from the female in 

 having the antennae bipectinate, with the branches shorter towards the 

 apex. It is on the wing in June, July and August,
