40 THE ZOOLOGIST. 
Mr. W. Nicholson exhibited several melanic varieties of Argynnis niobe 
and A. pales, collected by himself last summer in the Engadine. 
Mr. J. H. Leech exhibited a small collection of Lepidoptera formed last 
year by Mr. Pratt at Kiukiang, Central China. It included several new 
species, also specimens of a variety of Papilio sarpedon and other interesting 
forms. 
Mons. A. Wailly exhibited a collection of Lepidoptera lately received from 
Assam, containing upwards of thirty-five species of Papilio, Ornithoptera, 
Charaxes, Diadema, Cyrestis, and other genera. 
Mr. Meyer-Darcis exhibited specimens of Sternocera tricolor, Kerr, and 
S. variabilis, Kerr, from Lake Tanganyika; also two new species of Julodis 
from Syria. 
Mr. F. Merrifield exhibited, and mada remarks on, a long series of 
Selenia illustraria, S. illunaria, and E. alniaria, in illustration of his paper 
on “ Pedigree Moth-breeding.” 
Lord Walsingham exhibited, and made remarks on, a series of species 
representing the genera Snellenia, Wlsm., Gidematopoda, Z., and Hretmo- 
cera, Z. 
The Rev. T. A. Marshall communicated a paper entitled ‘*‘ A Monograph 
of British Braconide. Part IIL,” 
The Rev. Dr. Walker communicated a paper entitled “ Description of 
a variety of the female of Ornithoptera Brookiana.” 
Lord Walsingham read a paper entitled “A Monograph of the genera 
connecting Tinegeria, Wlk., with Hretmocera, Z.” <A discussion ensued, 
in which Mr. Stainton, Dr. Sharp, and others took part. 
Mr. Merrifield read a paper entitled “Incidental Observations in 
Pedigree Moth-breeding.” This paper contained a detailed account of 
experiments with Selenia illustraria, S. illunaria, and EF. alniaria, which, 
so far as they had yet proceeded, indicated that retardation of development 
in the growing stages of the larva, as well as in the pupal stage, was 
the cause of the darkening of colour in the perfect insects; that a low 
temperature had the effect of causing such retardation; and that growing 
the larvee at a forcing temperature tended to produce a warmer and yellower 
tint in the colouring of the moths. Lord Walsingham, Mr. Poulton, 
Prof. Meldola, Mr. White, and Mr. Merrifield took part in the discussion 
which ensued. 
Mr. J. H. Leech read a paper “Ona small collection of Lepidoptera 
from Kiukiang.” Mr. Elwes said he had examined this collection wich, very 
great interest, and was struck with the similarity of many of the species to 
those from Sikkim.—H. Goss & W. W. Fowter, Hon. Secretaries.
