in which the region between the band and outer margin was heavily 
suffused with dark grey scales. 
Melanio lepidoptera.— Mr. L. W. Newman, Odonoptera bidentata , 
ab. nir/ra, Phujalia pedana ab. mouacharia, Heinerophila abrnptaria ab. 
brunncata, Em atari/a atomaria ab. unicolorata, Dianthnecia conspersa 
ab. hetidandica and the chocolate coloured ab. of Ennomng antiinmaria. 
Mendelian inheritance of wing-markings.— Mr. L. W. Newman 
contributed the results of breeding the following species: —Abraxas 
grossulariata and var. rarleyata, 1907, 100 ova from var. varleijata 2 
and type A resulted in 1908 all type specimens; type specimens were 
paired and a partial second brood yielded 31 imagines—seven var. 
varleijata (4 , 3 2 )• Year 1909. Twenty per cent, of those bred w r ere 
var. varleijata. (however, 90 per cent, of the larvae died in March). That 
year he paired var. varleijata $ with a wild Bexley 2 , and a partial 
second brood yielded all types. In 1910 all typical specimens which 
he paired, but lost the strain as larvae in 1911. Ennoinos autamnaria .— 
In 1905 he received twelve ova from a type 2 captured at Dover. In 
190G eight specimens were bred, of which two w^ere the dark chocolate- 
coloured form, these two males were paired with typical females. In 
1907 he bred 30 per cent, of the dark form, paired up darkj and type 2 » 
and typej with dark 2 , but in 1908 only bred five specimens, including 
one dark 2 , all the larvae excepting five having died. The dark 2 he 
paired with type S (called Race No. 1 in following notes) also type $ 
and 2 (Race No. 2). In 1909 Race No. 1 produced five dark and four 
types. Race No. 2 all types, and there was great mortality in larval 
stages of this race. He then paired dark 2 with type $ , both from 
Race No. 1, and dark 2 Race No. 1, with type $ Race No. 2 = Race 
No. 3. In 1910 Race No. 1 produced 90 per cent, dark form No. 3, 
all died as larvae. Dark 2 s and $ s Race No. 1 vvere paired, dark 2 
and type $ No. 2, dark $ and type 2 No. 3. In 1911 No. 1 all dark, 
Nos. 2 and 3 each produced about 25 per cent, dark form with a great 
loss in larval stage. Pairings were then made as in 1910. In 1912 
No. 1 all dark. Nos. 2 and 3, 33 percent, dark. Callimorpha dominula. 
In 190G he paired the var. rossica $ with 2 • 1907 bred all types, 
pairings were secured, and in 1908, 25 per cent, of var. rossica bred ; 
of those he paired $ and 2 of the var. but could not get ova, so paired 
var. with type. 1909,12 percent, var. rossica bred, but no ova could be 
obtained, so he made pairings as in 1908. 1910 yielded 200 specimens, 
five per cent, of which were var. rossica. Wild blood was then intro¬ 
duced, type specimens being paired with the var. 1911 gave all types 
which were paired. 1912, 30 per cent. var. rossica, these were paired 
and fertile ova secured.

February 4th, 1913. —Lyc.ena argiolus.— Rev. C. R. N. Burrows, 
a long series bred from larvae found at Mucking feeding on flowers of 
Portugal laurel, to which pabulum he attributed their brilliant colour 
and large size. 
"Vanessa c-album ab.— Mr. G. H. Heath, a specimen bred autumn, 
1912, from a wild collected Herefordshire larva, the ground colour of 
wings being yellow.
