URANIA LEILCS. 
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 
larva: of kindred species (particularly that of T. 
Rhipheus ), 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- 
phalidw, 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.
