Differs from eson in being smaller and without the black patch 

 at base of hind wing. 



Larva brown, with numerous dark strigae on dorsal area ; lateral 

 area whitish, ventral grey; a large ochreous ocellus on fourth 

 somite, outlined in black and centred with 

 pink above, black below ; a series of six 

 decreasing ocelli on an ochreous line from 

 5th to 10th somites, ochreous, outlined 

 in black and centred with brown ; horn 

 pale, short, and rapidly running to a point. 

 Feeds on Ruhiacece. 



The form rafflesi is rather darker and 

 brighter coloured than theylia. The 

 larva is dark chocolate-brown, some seven 

 white subdorsal spots on thoracic somites; 

 seven ocelli on 4th to 10th somites, the first 

 largest, ochreous white, outlined in black 

 and with an ochreous-speckled black 

 centre, the others centred with brown : 

 horn dark brown, the tip ochreous, blunt, and of even diameter 

 throughout, from its base crimson streaks extend forward and 

 backward. Feeds on the same Ruhiacece as theylia. 



The form vinacea, again, is rather darker and brighter coloured, 

 with the larva pale brown, a narrow dorsal black line from 1st to 

 4th somite : pale subdorpal streaks on the same somites : oval ocelli 

 on fourth and fifth somites, ochreous, outlined in black and 

 centred with brown, on which in the first ocellus is an ochreous 

 streak, which in the second is crimson ; horn long, straight, and 

 pointed, brown with a white tip, with dark streaks extending 

 forward and backward from its base. Feeds on Impatiens. 



The imagos of these three forms are almost indistinguishable, 

 and whether we have here three good species breeding true, or 

 the larvae are in some way affected in form of horn, as well as 

 colour and the number of ocelli, by some conditions of life, we 

 have no evidence to show ; all were bred, preserved, and drawn 

 in the same locality by that most careful observer, Mr. E. E. Green 

 of Ceylon, who informs me that the larva of vinacea refuses to eat 

 the food-plants of the others.
