TROS. 305 



wings have a broad white patch crossing the end of the cell, 

 and a row of large red sub-marginal spots. The hind-wings 

 are long, with the hind-margin much waved, and sub-caudate. 

 The larva feeds on Aristolochia, and much resembles that of a 

 Thais. It is dark red, with several rows of short carmine 

 fleshy spines; about the middle is a transverse white band 

 slightly tinted with rose-colour. The pupa resembles that of 

 Tros hector. 



[LXXIV.] Tros, Barbut. The type of this genus is T. hector 

 (Linn.), a handsome and rather isolated Butterfly, which is 

 common in India and Ceylon. It measures about four inches 

 across the wings, which are rather long and narrow ; the tip of 

 the fore-wings is rather pointed, and the hind-margin oblique. 

 The hind-wings are long, dentated, and with a moderately long 

 and rather broad, but hardly spatulate, tail. The wings are 

 black, the fore-wings with two rows of long and mostly bifid 

 white spots, one near the tip, and the other running from 

 before the middle of the costa to the hinder angle ; the aind- 

 wings have two rows of large round red sub-marginal spots, 

 the innermost turning inwards at a right angle to the inner 

 margin at the end of the fold. The head, the body beneath, 

 and the greater part of the abdomen are red. 



The larva is smooth and green, with the hinder thoracic seg- 

 ments slightly thickened. The lower part of the body is brown 

 in front and white behind. On the upper surface there is a 

 narrow greyish band on the third segment, a transverse brown 

 band on the fourth, and an oblique white band, varied with 

 brown, on the seventh, which rises to the eighth ; the extremity 

 of the ninth segment is also whitish. The pupa is pale grey, 

 reticulated with brownish, with a bifid head, a projection on 

 the pectus, and the ventral surface of the abdomen serrated. 

 The larva feeds on the lime, and also on another species of 

 Citrus^ called " Jurok " in Java.
