CATERPILLARS. 217 



and white butterfly, strongly marked with red 

 and yellow on the under side, is light green, with 

 black spines on the hulnp, two yellow ones 

 terminating the body. The retractile fork in 

 this is yellow-brown, and a drop of liquid, 

 smelling strongly of orange and cashew, is 

 ejected from each point when it is thrust forth. 

 These caterpillars form a light green chrysalis 

 with a very long pointed head, suspended in the 

 same way as the last. ' 



The light green and brown caterpillar of the 

 lovely Papilio Colonna, a black swallow-tailed 

 butterfly with emerald-green stripes and spots 

 and two crimson spots on the hind-wing, is even 

 more like a fish than this last, as the tail is more 

 strongly marked and the yellow-brown spines on 

 the hump are branched, and consequently thicker 

 and more like fins. The chrysalis is very curious, 

 and only suspended by the tail. The first I saw 

 was attached to the under side of a half-eaten 

 leaf, the colour and the strongly serrated edges 

 resembling the broken leaf so exactly that I was 

 on the point of throwing it away.
