on the wing, Macaria notata, Eupecilia nana, commonly ; 
Argyresthia conjugella, plentifully; and a few specimens of 
(icophora subochreella and dAichmia dentella. I also reared from 
larve found in this neighbourhood during the previous autumn 
a fine series of the pretty Gelechia scriptella from maple leaves ; 
Ornix betulevorella, which was scarce, and Lithocolletis ulmifo- 
liella in plenty from birch leaves. JL. corylella was common, and 
L. nicelliella scarce from hazel leaves; L. acerifoliella in profusion 
from maple leaves; LZ. schreberella common from elm; Antispila 
Treitschkiella from dogwood: and eight of the rare Coleophora 
fuscocuprella from hazel.—Wuit1am Macuin; 22, Argyle Road,

TRIFURCULA ATRIFRONTELLA BRED.—In June last an insect 
emerged from one of my breeding jars which I did not know, 
and it unfortunately had so battered itself that recognition was 
difficult. Mr. Stainton, however, says that it is Trifurcula 
atrifrontella; and as nothing was in the jar except hawthorn 
leaves collected the previous autumn for larve of Nepticule, it 
appears certain that the larve of 7’. atrifrontella were feeding in 
the hawthorn at the same time. I remember noticing two or 
three blotch mines which then appeared distinct from Nepticula 
perpygmeella or N. ignobilella, but their number was so few that I 
thought it best to leave them with the others. The larvee were 
collected in October, and it is likely that had they been looked 
for in the previous month more of the larve of 7’. atrifrontella 
would have been found. The time of emergence does not agree 
with that given in Stainton’s ‘Manual.”—J. H. Ture rau;

NuMERIcAL RELATIONS OF THE SEXES AMONG LEPIDOPTERA. 
—There has been some amount of discussion on the relative 
preponderance in number of the two sexes among moths and 
butterflies. The trade catalogue of Kuropean Macro-Lepidoptera, 
issued by Herr A. Kricheldorff, of Berlin, seems to throw some 
light upon this question. In no fewer than 177 cases the female 
is charged at a higher price than the male, whilst in only eight 
cases is the male the dearer. ‘This surely proves that in a large 
majority of the cases where a notable sexual difference appears 
the female is, practically speaking, the rarer.—J. W. SuaTer; 
18, Wray Crescent, Tollington Park, N., January 21, 1880.
