HETEROCERA OF SIKEIM AND BHUTAN, 645 



two in August (Dudgeon). Exp. 52 millim. Type in British 

 Museum. 



There are several other species of this family found in Sikhim judg- 

 ing by the larva cases constantly being found, but they are extremely 

 difficult to rear. 



Family COSSIDiE. 

 Genus Cossus, Fabr. 

 651. C. acronyctoides., Moore. 

 Sikhim. I have only received two specimens, one of which was 

 taken in May. 



655. C. palhdalce^ Hmpsn. 

 Sikhim and Bhutan, 1,800 to 3,U00 feet. A family common species 

 in April and May, especially at Punkabaree at light. Perfect speci- 

 mens are, however, difficult to obtain. 



Genus DuoMiTus, Butl. 

 658. D. ceramicys^ Wlk. 

 Sikhim. I took two males of this species at light at Punkabaree in 

 July and August. It must be rare, as I have never seen others. 

 659. D. strix, Cram. 

 Sikhim and Bhutan, 1,500 to 2,500 feet. I took two specimens in 

 May, both females. It seems rather rarer than the last. 



660. D. leuconotus, Wlk. 

 Sikhim. I have not seen this from the locality. 



661. D. mineus^ Cram. 



Sikhim. I have seen six specimens of this species only ; one a female 

 in Dr. Pilcher's collection, another female taken, I believe, by Dr. 

 Seale near Darjeeling, two males which I took at light at Punkabaree 

 in September, and two females taken by me in August and September 

 in the same locality. 



662. D. fuscipars^ Hmpsn. 



Sikhim. (The type which was taken by one of Moller's native col- 

 lectors is the only specimen I have ever seen. — H. J. E.) 

 662a. D. pardalis, n. sp. (Plate I, Fig. 17, (^). 



Sikhim, 1,800 feet. Neuration as in Duomitus stigmaticus, Moore, 

 veins 4 and 5 of the hindwing being given off separately. 



$. Antennae brown ; head white ; thorax brownish- white, with a 

 narrow dark dorsal stripe with a row of three rather large black spots
