MIGRATIONS OF PAPILIONACEOUS INSECTS. 177 
actual and careful comparison, distinct species may 
have been confounded together. Many birds (par- 
ticularly of the order Grallatores) were once thus 
said to inhabit all parts of the globe; until it was 
shown, by careful and minute comparison, that 
different creatures had been confused together: I 
allude to the species of Scolopaa, Charadrius, Tha-

characters, to be distinct. There can, however, be 
no doubt but that the Painted Lady Butterfly has 
an amazingly wide range of geographical distribu- 
tion, and I think it may be fully accounted for by 
the strange wandering propensities of the insect. 
“ Of this I have just witnessed a very remark- 
able example. I had often observed this species 
to fly straight out to sea, and I have noticed it at a 
considerable distance from land; but, until within 
this last fortnight, I never knew them travel in 
immense flocks. On the 8th of this month, (Oc-

twenty were counted on one clump of dahlias ; 
and, at the same time, they were noticed in equal 
abundance in a garden about half a mile distant 
from that in which those dahlias grew. None
