HETEROCERA OF SIKHIM AND BHUTAN. 417 



Subfamily Maceoglossin^e. 

 Genus Gurelca, Kiebt. 

 173. G. hyas, Wlk. 

 This is a very common species in Sikhim and Bhutan occurring up 

 to at least 5,000 feet. It is found chiefly at the lower elevations 

 from May to July, and again in November and December. The figure 

 of G. hyas in the "Fauna of British India, Moths," vol. i, more resem- 

 bles the next species. All my specimens of G. hyas have the marginal 

 band on the hindwing almost even in width throughout, and the 

 forewing is broader. 



174. G. masuriensis, Butl. 

 Sikhim. Occurs at 1,800 feet and upwards. My specimens were 

 obtained in May and July. It is not nearly so common as the last. 

 175. G, macroglossoides, Wlk. 

 Sikhim. I have never seen this species. Mr. Elwes doubts it being 

 a good species, and remarks that Sir George Hampson does not seem to 

 know it except from Walker's description. 



Genus Rhopalopsyche, Butl. 



177. R. nycteris, Koll. 



Sikhim and Bhutan. Occurs from 5,000 to 10,000 feet. I have 



taken it commonly at the first elevation on the Tukvar spur, where it 



may be found sucking up honey from flowers in May and July. The 



yellow band on the hindwing is very pale. 



Genus Macroglossa, Scop. 

 181. M. gyrans, Wlk. 

 Throughout India (Hampson). I have never seen it from Sikhim 

 or Bhutan. ( I do not think this occurs in the Hills. — H. J. E.) 

 184. M. belts, Cram. 

 Sikhim and Bhutan, up to 3,000 feet. Occurs in June, July and 

 November. The distinctive characters appear to be the reddish- 

 orange band of the hindwing, and the postmedial band being brown, 

 not blackish. 



186. M. proxima, Butl. 

 Sikhim and Bhutan, up to 2,000 feet. Occurs in July, tart is less 

 common than M. belts, from which it differs in the discal band of the 

 hindwing being yellow, and the postmedial band blackish.
