HETEROCERA OF SIKHIM AND BHUTAN. 37 



any other species of the Notodonttdce ; the length of the third joint of 

 the palpus, the tufts on the proximal segments of the abdomen, and 

 the abnormal neuration of the forewing make its position uncertain. 

 Genus Cyphanta, Wlk. 

 322. C. .vanthochlora, Wlk. 

 Sikhim, 9,000 feet. This, it would appear, is not uncommon at the 

 elevation named, where Dr. Pilcher seems to have obtained several 

 specimens. I have two males taken in July. Mr. Elwes remarks that 

 it is probably a local insect, as his collectors never procured it. 

 Family CYMATOPHORIDiE. 

 Genus Habrosyne, Hiibn. 

 324. //. derasa, Linn. 

 Sikhim, 5,500 feet ; var. fmterna, (Moore), Yatung, 12,000 feet 

 (^Tayloi'), It is found in October, and does not seem to Ijc common. 

 I receive<l one specimen of the \[iv\eiy fraterna, (Moore), from Yatung, 

 which agrees exactly with Mr. Butler's figure. 

 325. II. pJag/osa^ Moore. 

 Sikhim. I have never received this species. 



327. II. argeiiteipuncta, Hmpsn. 

 Sikhim and Bhutan. My only specimen was taken below Lingtu at 

 6,000 to 7,000 feet in August. 



328. H. sangu'inea, Moore. 

 Sikhim. I have not seen a specimen. 



Genus Thyatira, Hiibn. 

 329. T. hatJs, Linn. 

 Sikhim, 5,000 feet. I have taken this species at 5,000 feet in 

 October ; Mr. Elwes took it at Darjeeling in May and July, 

 329a. T. decorata^ Moore. 

 Sikhim. Sir George Hampson suggested that this was a distinct 

 species, although he included it with T. hatis, probably not having 

 sufficient material to determine. Mr. Elwes has four specimens which 

 do not show any variation, and he agrees that it is perfectly distinct 

 from T, balls. 



Genus Gaurena, Wlk. 

 330. G. Jlorens, Wlk. 

 Sikhim and Bhutan, 3,000 to 7,000 feet. My specimens were 

 pbtained in August, September and October, but it probably occurs
