related to Wagner’s and Meinert^s larvse.

A. R. Wallace has communicated to the Entomological 
Society of London (Proc. Ent. Soc. 1864, p. 15) some observa- 
tions on polymorphism as exhibited in certain species of But- 
terflies. After distinguisbing between polymorphism and simple 
variation, he indicated the occurrence of dimorphism ” in 
Papilio memnon (which has two forms of females, both different 
from the male) , and probably of trimorphism ” in Papilio 
pammon, one female of which resembles the male, a second has 
been described as P. polytes, and P. roainlus ajjpears to be a 
third. P. armeniis has three distinct forms of females, all dif- 
fering from the males ; and in some cases the number of female 
forms appears to be four. 
A. R. Wallace also communicated to the same Society (Proc., 
Ent. Soc. 1864, p. 21) some remarks on the effect of locality in 
producing change of form in insects, illustrated by species of 
Papilio, Eronia, and Picris from Celebes and the neighbouring 
islands. lie noticed that the Butterflies inhabiting the eastern 
half of the Indian archipelago, and especially those of Celebes 
and Amboyna, were generally larger than those in the western 
half ; many of the species from Celebes had the costa of the 
anterior wings more arched than their nearest allies from the 
neighbouring islands ; and some species, which in India have 
large tails to the hind wings, gradually lose these appendages as 
they are traced eastwards. Papilio agamemnon is an example 
of this. Wallace regards these facts, especially the falcation of 
the wings in the Papiliones and some other Butterflies of 
Celebes, as indicating that in former times these insects were 
subject to some great persecution, which the curvature of the 
wings would give them a better opportunity of eseaping by faci- 
litating a rapidly tortuous flight : thus, by natural selection,” 
the individuals with falcate wings would gradually predominate. 
The facts brought forward by W allace, and his deductions from 
them, were discussed by the members of the Society (sec Proc. 
Ent. Soc. 1. c. pp. 22 & 23) . 
Bellier de la Cliavignerie gives some account of the results of his entomo-

Lepidoptera and Coleoptera) which he has tahen in that island. Bull. Soc.
