204 URANIA LEILUS. 



been noticed by any competent observer since the 

 time of Madam Merian, at least no notice of it has 

 been published since. It was long suspected that 

 her figure of it was unworthy of credit, but from 

 what has been recently observed in relation to the 

 larvae of kindred species (particularly that of T. 

 Rhiphens), it now appears probable that her infor- 

 mation was correct. Anomalies similar to those 

 which characterise the perfect insects, likewise at- 

 tend them in their previous state. They are covered 

 with spines, as is the case among many of the Nym- 

 phalidce^ and they are provided with a retractile 

 tentaculum as in Papilio. In the present instance 

 the spines are remarkable for their length and rigi- 

 dity, particularly those on the anterior and posterior 

 segments.
