elevation of 10,000 feet iu Sikkim. It was orig-inally referred to the 

 genus Saiurnia, but the observations of Mr. A. V. Kny vett indicate 

 pretty clearly that it should rather be included in the genus Salassa. Ac- 

 cording to Mr. Knyvettj the caterpillars are very like those of Salassa 

 lola, only bigger; the chrysalis also is formed in the ground in a little, 

 loose silk, much as is the ease with Salassa lola. 



The male was figured from specimens determined by Mr. H. J. Elwes, 

 the female from a specimen deposited for a short time in the Indian 

 Museum by the late Mr. Otto Moller. 



Caligula. Simla, Westw. Flate 14, fg, 1. * 



In the Indian Museum are specimens of this species from Simla, 

 Mussoorie, Sikkim, and Khasi Hills, besides cocoons which are supposed 

 to belong to it and which were obtained in Dehra Dun, probably from 

 the Mussoorie Hills. Button writes (Journ. Agri. Hort. Soc. Ind., iii, 

 1871, p. 1^5) that the larva feeds on walnut, Salt/uc babylonica, and 

 wild pear, the cocoon being a coarse open network, through which the 

 pupa is visible, and yielding no silk. 



Caligula thibeta, Westw, Plate 14, fig. 2. 



In the Indian Museum is a male of this species obtained from Sik- 

 kim. According to Hutton (Journ. Agri. Hort. Soc, Ind., Ill, 1871, 

 p. 125) the original specimen from which the species was described came 

 from Kumaon, and he also found it in Mussoorie on Pieris ovalifolia. 

 It seems to be a well marked species, quite distinct from C. simla. A 

 third species of the genus Caligula, viz. C. cachara^ was described by 

 Moore (P. Z. S. 1872, p. 578) from Cachar ; there are no specimens of it 

 in the Indian Museum. Butler (III. Typ. Lep. Het. B. M. V, p. 61, pi. 

 94), fig. 2, 1881) describes a species from Sikkim, under the name of 

 Binaca extensa. From the figure this insect would seem to be indistin- 

 guishable from C. thibeta.

RiNACA ZULEIKA, Hope. Plate 14, fig. 3 (Trans. Linn. Soc, Lond., 

 XIX, p. 132, pi. 11, fig. 5, 1845). 



This species has been recorded from Sylhet, Sikkim, and Simla ; the 

 Indian Museum possesses moths from Sikkim, also a single chrysalis case, 

 but no cocoon. Rondot iV Art de la Soie, II, 1887, p. 205) writes that 

 the cocoon is reticulated and without economic value. According to 

 Moller, the caterpillars feed in Sikkim upon the plants ActinodapJine 

 siJckimensis and Acer caudatum vel camphellii. According to Mr. A, V. 

 Kny vett, the caterpillar is to be found at an elevation of about 7,000
