The greater part of these groups, which also contained a 
few moths belonging chiefly to the genus Pericopis, consisted 
of species of the Heliconioid Danaine or, as they had been 
recently called, Neotropinz; one or more species of Heli- 
coniude were constantly present, and the associated forms of 
Heliconius might conveniently be regarded as representatives 
of the respective colour-types. A few Nymphaline, Pierine, 
Papilioning, and in one case an Erycinid, had been drawn 
into the vortex. The colour-types which they represented 
were so far diagnostic of the geographical distribution that 
4, strange specimen belonging to one or other of these groups, 
which were a few only out of many such that could be put 
together, could be unhesitatingly assigned by its facies to its
