316 Mr. F. Moore on the 



Ceylon specimens have been named by some siViihov^ Att. Arethusa ; 

 but this 'name has been applied to a Brazilian species of Atlacus. 



Attacus Edwardsii, White, Proc. Zool. Soc. 1859, pi. 57. 



Inhabits Sikkim, and differs from Att. Atlas in being much 

 darker, the disc of both wings being black, the transverse bands 

 much broader and white, and in having the ocelli inwardly bor- 

 dered with yellowish ferruginous. It also has an additional black 

 spot below the apex of the fore-wing.

Att. Canningi, Hutton (18G0). 



Inhabits China (where it feeds, according to M. Guerin-Mene- 

 ville, on Ailanthus glandiilosa), also the Sub-Himalayas. Specimens 

 from Hong Kong, Java,* Nepal, Darjeeling and Kemaon are alike, 

 but differ in size; those from Hong Kong exceeding 6 inches, the 

 Nepalese 5, the Mussooree not over 4|, while those from Java 

 vary from 3| to 6 inches. It is very common in a wild state at 

 Mussooree, where, states Capt. Hutton in epistola, "it feeds on 

 Curioria Nipalensis and on the Tex Bui {Xanthophyllum hostile). 

 It will likewise eat the leaves of Ricinus communis, but does not 

 take kindly to them. It can also be reared on the Cape wood- 

 bine. It is only an annual." This has been cultivated for cen- 

 turies in China, where its silk clothes masses of the people. It is 

 also extensively reared in Assam. The Eria has been introduced 

 into Malta, Piedmont, Tripoli, France and Grenada, and I believe 

 also into Algeria. It is, together with a hybrid-j- between it and 

 the Bengal Eria, successfully cultivated in the open air in many 

 parts of France (where it was introduced by M. Guerin-Meneville 

 in 1859), and is there reared on the Ailanthus, its silk being 

 turned to profitable account. 



This hybrid, eggs of which M. Guerin-Meneville kindly 

 forwarded me, was, by myself, reared in London on the Ricinus 

 communis.

* The " Eria"' of Java has been named Attacus insularis by Vollen Hoven. 

 t This hybrid has been named in Fiance Sat. Vesta, but by whom I am un- 

 aware. Specimens received from the late M. Becker were so named.
