32 THE ENTOMOLOGIST’S RECORD. 
Notes on the Micro-lepidoptera of South-West London.

(Continued from vol. xavii., p. 151.) 
Hyponomeuta vigintipunctatus, Retz.—Two moths were bred in 
April, 1907, from pupe given me by the late Mr. George Nicholson. 
He had bred several specimens from larve found on Sedum telephium 
in Kew Gardens in the previous September (Bull. of Miscellaneous In- 
formation, Royal Botanic Gardens, Kew, No. 5, 1907, p. 188). 
The eggs of this species are laid on the leaves of the foodplant and 
the larvee, passing through the base of the egg-shell, mine through the 
thickness of the leaf before coming into the daylight. 
Hyponomeuta plumbellus, Schiff—One imago taken in Chiswick, 
October 7th, 1915. This is a very late date, but the species of this 
genus often remain on the wing for a long period. I have found the 
imago elsewhere on Euonymus japonica, and if the species has taken to 
this as a foodplant it may, like HY. cognatellus, be able to extend its 
range to suburban districts. At Cookham, Berkshire, I found the 
young pale yellow larve living in solitude in the interior of the shoots 
of H’. ewropeus in May. The bored shoots were quite yellow. When 
older the larve feed on the leaves under a web. 
Hyponomeuta padellus, L.—Chiswick, apple and hawthorn. Ham 
Common, blackthorn. Doubtless throughout the district. The larval 
nests are very common on whitethorn and also occur on apple and 
sloe. Some doubt has been expressed as to whether the apple-feeding 
larve produce this species. Owing to lack of details this question has 
not yet received a definite answer, but so far as my own knowledge 
goes, it leads me to the opinion that H. padellus is a most variable in- 
sect and that its larva feeds on apple as well as on other trees. On 
the continent there is an apple-feeding species, the H. mallinellus of 
Zeller (/sis, 1844, p. 198), and possessing specimens of Zeller’s species, 
I feel sure that the insects 1 have seen, bred from apple in Chiswick 
and elsewhere in England, are not Zeller’s madllinellus, but belong to 
his variabilis, which is usually considered to be cospecific with the 
padellus of Linneus. The whitest specimens bred from apple in 
Chiswick are not snow-white, like the smaller madlinellus or like H. 
cognatellus, but grey white. The darkest specimens are from hawthorn 
while those from blackthorn are intermediate. All together they form 
a graduated series from white, through white clouded with dark grey, 
to entirely dark grey. Sometimes the underside of the forewing shows 
a narrow whitish costal line and the fringes are partly whitish but not 
to the same extent as in H. mallinellus. Like the other species of this 
genus the black dots vary on the opposite forewings of the same speci- 
men. On the hawthorn the eggs are laid in batches on the twigs and 
the larve hatch out in late summer but remain under the egg-shells 
till spring. R. H. Lewis, in 1834, first called attention to this fact 
and also stated that the larve on leaving their shelter first mined the 
leaves before commencing to live under a web. This I believe is also 
true. Lewis was writing of the larve on apple (Trans. Hnt. Soc., ser. 
Tes VAG ths 725 2a)
