142 THE ANCHISES BUTTERFLY. 



On these trees are found great numbers of the cater- 

 pillars of the Anchises Butterfly, collected together 

 in groups, and adhering to each other like snails. 

 Their colour is brown, the annulations being inter- 

 sected by numerous white longitudinal stripes ; and, 

 when touched, they protrude from their front a pair 

 of soft, yellowish horns, as if to defend themselves, or 

 to attack their enemies. Madame Merian kept some 

 of these caterpillars on lemon leaves till the 20th 

 March ; at that period they changed into a chrysalis, 

 out of which, on the 2d of April, proceeded the 

 Butterfly.
