HELICONIA. 
depressed, -with a series of long fleshy lobes on each 
side ; that of II. Calliope short and cylindrical, 
clothed with slender spines and tufts of hair : these 
species form the genus Nerias, although they are 
too dissimilar to he associated with propriety. Others 
are smooth ( II. Ps'ulii ). and some are covered with 
very long white hairs (H. liicini ). In these cir- 
cumstances, it is not likely that a natural arrange- 
ment of this pretty group will be effected until we 
become better acquainted with the caterpillars, very 
few of which have hitherto been examined. Chry- 
salis invariably suspended by the tail only. 
These insects, as has been already mentioned, are 
confined to America and the West India Islands, 
the larva subsisting on the different kinds of Passi- 
florce, a beautiful tribe of plants well known to be 
likewise peculiar to the new world. They seem to 
be represented in India, as Dr. Horsficld remarks, 
by the genera Euplcea and Idea.
