the commonest wild silkworms of Assam. It occurs 

 in the Assam valley, undev both the northera and , 

 the southem hüls, and likewise in Cachar, where j 

 the wild tea-plant ofteu supplies it with food. It is j 

 also frequently found on .smu trees. Its favourite 

 tree, however, is tiie mango, whether the wild mango 

 of the forest, or the cultivated trees in the vicinity 

 of villages. The Aniluri spius a bright yellow co- 

 coon, in Clusters so closely interwoven that they 

 canuot be separated for reeling, which, indeed, their j 

 very texture prohibits. In the number of broods aad j 

 times of breeding this worin is said to correspond 

 with the Miuid. The worm is covered witli hairs, j 

 which produce Irritation of the skin, and for this reason \ 

 it is regarded as iinclean by the Hindus; but Ka- 1 

 charis, Räbhas, and Meches occasionally mix the 

 silk with the cri, wehre it reveals its presence by 

 the itching it causes; this irritatiug property of the j 

 worni is said to protect it against crows and bats. 

 The chrysalis, however, is eateu by Kacharis, Räbhas, 

 Mechas, and Mikirs. A smaller variety of the Aidu- 

 l(iri. called hi^lid. and feeding, like the Ainluri, on 

 the mango tree, is found in small numbers in the 

 Sub-Himalayan jungles of Kämrüp. The name ex- 

 presses the irritating quality of the worm. 



8. I)roii/ti(/ri iBootOi/.r )rl/(//osarl . — The Dm- 

 iiiiiijK silkworra is so called from its size. It is the 

 largest of all the worms, attaining a length of 

 6V2 iuches, and it is also the haudsomest. This worm 

 appears at times on siim trees with the Mutia, but it is of 

 rare occurreuce. The worm in its secondandthirdstage 

 is particularly handsome, with rows of turquoise spots 

 on its side. Wheu the worm enters upon its fourth 

 stage, the turquoise spots vanish, and spots of gold 

 appear in their place, and on each side of the body 

 stripes, having all the colours of the rainbow, tend 

 to make this worm by far the most beautiful of its 

 tribe. The Deoimifja worm is said to live thirty | 

 days, and to spend three days in spiuuing its cocoou; 

 the period of the chrysalis is fifteeu days in the hot, 

 and tbirty days in the cold season, and the life of 

 the moth lasts about four days. The cocoon is large 

 (3 in. by l'/2 io), and gives a large quantity of 

 strong but coarse and dark-coloured silk. The hard- 

 ness of the cocoon renders it difficult to reel, and j 

 the silk easily gets into knots. The thread of the 

 Deon/iif/a is said to be used for fishing lines in 

 Bengal. In Cachar, the Dco/i/nf/a feeds on the 

 banyan (Fii-iis indica) and pipal (F/ois nlif/ios/O. 

 The worm occurs, generally, in the .Vssam valley. 



9. Aclid.y si-liiH'. — This silkworm occurs in 

 Cachar but very rarely. The cocoon yields but little 

 silk, and no attempt is ever made to use it.
