The larva, chrysalis, and cocoon of C. trifenestrata are figured in 

 the * Catal. of Lepidoptera ' in the Museum, India House, vol. ii. 

 pi. 27. figs. 7, 7 a, 7 b, copied from the original drawings made under 

 Dr. Horsfield's superintendence in Java. The larva (according to 

 Dr. Horsfield) " feeds on the Teng-gulung (Protium javanum), the 

 Kettos (Canarium commune), and the Ingas (Mangifera ingas ?). 

 Abundant during December and January ; scarce in March." 



The cocoon is of a beautiful yellow colour, and of a rich silky 

 lustre, and constructed like network, the enclosed chrysalis being 

 visible. 



Discovered in Assam by Capt. Jenkins, " where it lives on the 

 Soon teee, but seems to be not much used" (J. A. S. Beng. 1837, 

 p. 46) ; and at Moulmein by Capt. J. C. Haughton, who states that 

 he " only observed it upon the Cashew-nut tree (Anacardium orien- 

 tal e), which, though exotic, has thoroughly taken root both at Tavoy 

 and at Moulmein, and is now to be found in every native garden 

 (Journ. of the Agri-Horticultural Soc. of India, 1858, p. 101)."

 p. 1250. 



Antennas deeply bipectinated. Abdomen short, rather thick. 

 Wings broad; fore-wings without ocelli; fore- wing with costal margin 

 convex towards the tip, where the angle is falcated ; posterior angle 

 round, inner margin somewhat straight ; hind-wings with ocelli ; the 

 apex round, the anal angle less so. 



Remark. — This genus, of which only one species is as yet known, 

 may be distinguished from Anthercea by the absence of the ocellus 

 in the fore-wing, — all the known species of Anthercea possessing a 

 distinct but varying ocellus in both the fore and hind wings, whereas 

 in Salassa it is replaced by a small diamond-shaped vitreous spot.

Wings rich brownish-red ; fore-wing with an obscure transverse 

 line near the base, a small diamond-shaped vitreous discal spot, fol- 

 lowed by a transverse dark dentated line, beyond which is a greyish- 

 brown fascia bordered on each side by a dark dentated line, and ter- 

 minated at the apex in a grey patch ; hind-wing paler at the base, 

 with a black-centred ocellus, which is encircled by a white and then
