HE TE ROC ERA OF SIKHTM AND BHUTAN. 243 



7. A. ricini, Boisd. 

 Sikhim, 5,500 feet, September. T have only obtained one specimen 

 of this species, and have never seen another from the locality. The 

 larva is reared for its silk by the Mechi and Garo tribes of the Terai 

 and Duars. 



Genus Antherea, Hiibn. 



8. A. roylei, Moore. 



Sikhim, 2,000 to 3,000 feet, September. (May to September. Ac- 

 cording to Knyvett feeds on oak at 3,000 to 4,000 feet,— H. J. E.) 



9. A. paphia, Linn. 



Sikhim [Otto Moller), April. The only specimens I have are a pair 

 given to me by Mr. Moller and labelled "Sikhim, April, 1888." 

 (According to Knyvett occurs in the Terai only, where it feeds on 

 "Ber."— H. J. E.) 



10, A knyvetti, Hampson. 



Sikhim, April. One specimen only. (Occurs at higher elevations 

 than the other species. Feeds on wild cherry, according to Knyvett, 

 Though Mr. Knyvett, who had bred this species, considered that it 

 could certainly be distinguished from A, roylei by the larva and cocoon, 

 and though some specimens given me by him as typical do shew the 

 differences indicated by Hampson, yet there are intermediate forms, 

 which I cannot certainly identify with either species. — H. J. E.) 

 11. A. helferi, Moore. 



Sikhim, March. The cocoons have been brought to me in some 

 quantities from l< Sal " forest at low elevations. 

 12. A. assama, Westw. 



Himalayas from Kangra to Assam (Hampson). I have never 

 received this species from this locality. (I have two specimens from 

 Sikhim which agree with A. assama as described by Hampson, but 

 have the marginal lines of the hindwing nearly straight, not as in 

 Westwood's figure. 1 distinguish this species by the ocellus of the 

 forewing being almost, in some cases quite, without a pupil. Khasia 

 specimens are of a dark purplish-crimson colour. — H. J. E.) 

 14. A. frithi, Moore. 



Sikhim and Bhutan, 2,000 feet, March. As far as my experience 

 goes, this is by far the commonest Antherea found in Sikhim. The 

 larva feeds on " Sal," and wherever the tree occurs in forests, the
