Cachar, feeding on the castor-oil plant (Ricinus communis), 

 yielding seven or more crops annually. Cocoons somewhat 

 loose and flossy, orange red, sometimes white. The so-called 

 "Ailanthus silkworm" of Europe — the result of a fertile 

 hybrid between the Chinese and the Bengal species, was 

 produced some years ago in France, by Monsieur Guerin- 

 Meneville, and subsequently reared, from whence it was 

 introduced into various parts of the world. 



Attacus Ganningi (Hutton). — N.W. Himalayas. Com- 

 mon in a wild state, feeding on the leaves of Goriaria 

 nipalensis and Xanthophyllum hostile. Cocoons hard and 

 compactly woven, rusty orange or grey. An annual. 



Attacus lunula (Walker). — Silhet. 



Attacus obscurus (Butler). — Cachar. Not very common. 

 Stated to feed on a plant called Lood. 



Attacus Gue'rini (Moore). —Eastern Bengal. 



Actias Group. 



Actias Selene (McLeay). — Mussooree, Sikkim, and Khasia 

 hills ; Madras. The worms feed upon Andromeda ovali- 

 folia, Goriaria nipalensis, wild cherry, and walnut, at 

 Mussooree, and on Odina ivodier in Madras.

Anthercea mylitta (Drury). — Anthercea paphia of 

 authors ; the Tasar, Tusser, Tussar, or Tussah silkworm. 



These well-known and valuable insects (of various unde- 

 termined species) are widely distributed over India, from east 

 to west and north to south, on the coast, and in the Cen-

 ber {Zizyphus jujuba), the asun (Terminalia alata), the 

 seemul (Bombax heptaphyllum), &c. 



Anthercea mezankooria (Moore) ; the Mezanhoorie silk-

 mezankoorie silk are stated to feed on the addakoory 

 (? Tetranthera sp.), which is abundant in Upper and Lower 

 Assam. The silk is nearly white, its value being 50 per 

 cent, above that of the moonga.
