Sexes are equal 13 ^s, 14 2 s. The females, with the exception 
of one, which is lighter, are all as dark or slightly darker than the 
$ parent, only two having any tendency to the blurred and suffused 
central band of the 2 parent. Of the 14 2 s all but one are more or less 
dark and suffused, some to a greater extent than the 2 parent. Bhood E. 
(Parents: a dark and suffused 2 with a normal $ ):— 8 $ s and 11 2 s :— 
Four of the $ s are much darker, three are about the same shade, 
and one is slightly paler than the $ parent. Of the 2 s two are 
slightly darker than the 5 parent, the remainder having the suffused 
tendency to only a slight extent. Brood B. (Both parents pale). 
Shows a large proportion of 2 s, 26 against 14 $ s, variation of 
colour slight, all follow the parents closely. Brood A. (Parents 
rather strongly but distinctly marked). 11 $ s, 12 $ s, folloAV the 
parents closely, general tendency for the markings to be strong and 
clear. The suffusion of colour in Broods I and A seems to arise chiefly 
from the darkening of the generally faint and interrupted line parallel to, 
but on the inner side of, the elbowed line. There is on the whole a tendency 
to breed true, and for the $ s to follow the $ parent and the 2 s to 
follow the 2 parent. I paired a number of these 
moths bred last year, and on going through my boxes containing the 
ova I made the following notes: In-Breeding.— Of two pairings of I 
with I one produced no ova and the other a fair number of apparently 
fertile ova, the 2 in the latter case was a cripple ; of four pairings of 
B with B, all produced medium to large batches of ova all of which 
look fertile. Crossing.— Of three pairs of I with E (1) produced a few 
ova, not all fertile, (2) very few ova and very few of these fertile, (3 i 
a few ova all or nearly all fertile. One pair (A with B) produced 
a fair batch of ova, most look fertile. One pair (A with I) produced 
a lot of ova, all of which look fertile, the 2 was a cripple. I 
also paired a 2 of A with a $ bred from a larva beaten in the 
New Forest last year; very few ova were laid and none of 
them look fertile. It will be seen that brood B seems more prolific 
of fertile eggs then the other three, probably this is owing to the 
parents of this brood having been of different stocks. It is also 
remarkable that both the crippled 2 s of brood I (one of which was 
paired with a $ of the same strain, and the other with a $ of brood 
A), produced fair-sized batches of apparently fertile ova, while well 
developed 2 ’s of the same stock laid few if any fertile ova. I found 
much greater difficulty in pairing dark moths with dark moths than in 
crossing light with light or light with dark, and this quite irrespective 
of their being of the same or different broods.” Mr. Bayne exhibited 
the following aberrations : Polyornmatus icants: males of the following 
forms—(1) Lilac blue. ( 2 ) Bright blue. (3) Bright dark blue. (4) With 
slight trace of black spots on hind margins of wings. Coenonyuipha 
jkuii jihHits: ( 1 ) Pale form from Aylesbury. (2) Dark form from New 
Forest. Plebehts aeyon (undersides) from the New Forest: (1) With 
slightly coalescing spots. ( 2 ) With spots on hind-wings forming a 
short band. ( 8 ) With the last pair of spots on fore-wings wanting. 
Also specimens of Polyornmatus astrarchc and /’. icants, showing parallel 
aberration to the P. aetjon marked 8 above, llybemia defoliaria: 
( 1 ) With strong melanic tendency. (2) Dark unicolorous form. (3) 
With band continued across the hind-wings. (4) Two forms of the 
female — typical and melanic. Mr. May recorded a specimen of 
Phitjalia jmlaria, seen on a lamp at Tooting, on January 26th last.
