BUTTERFLIES. 115 



feet. Theophila Huttoni, whose caterpillars feed on the leaves of 

 Artocarpus chaplasha, spins a cocoon not unlike the domesticated silk- 

 worm, Bomhjjx mori, of l^urope and Asia. Bomhyx mori itself is not 

 recorded from Sikhim, and probably does not occur there in a wild 

 state. Attempts are now being made to introduce it on a commercial 

 scale, and if successful must prove of great benefit to the Lepchas, 

 who are sadly in need of some such cottage industry. Other insects 

 numerously represented in Sikhim are beetles, bugs, grasshoppers, 

 leaf-insects, praying-insects, walking-stick insects, dragon-flies, ants, 

 lantern-flies, Cicadce, etc. 



It might be noted that the Lepcha collectors of Sikhim are most 

 skilful, and would compare favoumbly with those of any country in 

 the world : they are the only race in Hindostan who have names for 

 the different species of butterflies. 



N.B.—Attacus cyntMa and Cricula trifenestrata are also hopeful species and are very 

 common. A. cynthia is more than a hopeful species, it = A. ricini or the " ende " silkworm 

 of commerce. Crictila trifenestrata has no silk worth the trouble of reeling. A hand-book 

 on the Indian Moths ia now in course of preparation by Mr. G. F, Hampson.
