occurrence as a weed in tea gardens ; stature middling ; 

 common in jhum lands, less so in primitive forests. 



4. Nagdana (Artimisia sp.). 



5. Monphul (Cachar name), known in Dacca as the 

 Myna kata. 



6. Balos, a weed fed on also by the Attacus Canningi. 



7. KoorJcooree, one of the commonest of jhum weeds, one 

 of the most eligible for training the Atlas worm. 



8. Lutki (Osbechia), a very small plant, but the silk off it 

 is very white. 



9. Bon Chelita, a large, hardy, rapidly growing tree, 

 sufficiently common for the purposes of silk cultivation. 



10. Kadam (Nauclea). 



11. Chelita {Dellenia speciosa), eminently adapted for 

 training the Atlas worm. 



12. Boidraj (Padrelace ?) The silk off this plant is very 

 dark.

anther2ea yama-mai. 



This species is a native of Japan, although it is found 

 also in China, and has been introduced into India, thougn 

 very sparingly. 



In Japan its silk is said to be most highly prized, and 

 reserved for the use of Royalty ; but as to being so of late 

 years I am inclined to doubt, as the silk is not very fine, and 

 I saw many woven specimens of it in the Japanese silk 

 exhibits in the Paris Exhibition of 1878. The cocoon 

 is of a beautiful pale-green colour (Plate XVIII., Fig. 2). 

 It has been naturalised in Europe, and is a very hardy 

 species. 



A cross between the A . yama-mai and Bombyx Attacus 

 pernyi is a great success in France. It is so hardy that 

 hatching is said to take place at freezing-point. I have 

 recommended the Government of India to encourage the 

 acclimatisation of this species in India, as I feel certain it 

 yields a most useful species of silk ; and although a coarser 

 fibre than that of Bombyx mori, it is finer than that of 

 Anthercm paphia, and it has a very glossy appearance
