Mr. Bates said that this explanation quite accorded with his own views 
on the subject. 
Mr. Smith enquired the exact meaning attached to the terms “ migratory” 
and ‘‘non-migratory,” as applied to insects, in connection with Mr. Miller’s 
paper. 
Mr. Stainton suggested that in the one case the insects might be 
considered free agents, whereas, in the other, compulsion was necessary to 
force them from their customary habitats. But it was remarked that the 
terms were ill chosen, inasmuch as migration, in the sense in which the 
term is applied to birds, does not exist with insects, much of the so-called 
migration of these being dependent upon the supply of food being insufficient 
to satisfy the wants of vast hordes of a particular species; this, in some 
cases, as in the locusts, being the normal condition, rendering them habitual 
wanderers, whereas, in others, it was of only occasional occurrence. 
Mr. H. Jenner-Fust communicated a supplement to his paper “ On the 
Distribution of Lepidoptera in Great Britain and Ireland.”
