THE LEPIDOPTERA OF LEYTON AND NEIGHBOURHOOD. 159
S. mendica. Taken occasionally on the wing (female); not
taken in Forest.
Euchelia jacobeae. Never seen at Leyton ; common in larval
form on ragwort about High Beach, much less common as imago.
Bombyx quercus. Never taken in garden; larva fairly
common on grassy banks about Chingford and Walthamstow.
B. neustria. Abundant in garden as larva and imago.
Odonestis potatoria. Same remarks apply as under Bombyx
quercus.
Saturnia carpini. I have never seen this species in the
Forest, but its larva is sometimes taken about the heathy parts.
Cilix spinula. Occasionally on wing in garden; more com-
monly in Forest.
Platypteryx falcataria. Beaten from birch in Forest about
Theydon Bois ; never taken at Leyton.
P. hamula. Once taken in garden ; occurs (somewhat rarely)
in Forest.
P. unguicula. Not uncommon among beech at Monk's Wood.

a roadside bank near the "Robin Hood."
NOCTUAE.
Thyatira derasa. At sugar in garden occasionally; com-
moner in Forest.
T. batis. Not uncommon at sugar in various parts of Forest;
not taken in garden at Leyton.
Cymatophora duplaris. Occasionally at sugar in Forest
("Rushey Plain").
Bryophila perla. Taken in profusion on wall by Lea Bridge
Station, and also on a wall at Loughton. I have not seen the moth
in the Lea Bridge locality of late years.
Acronycta tridens and psi. Both species occurred at Ley-
ton ; but were not recorded separately, as I was then unable to dis-
tinguish them.
A. aceris. Larva occasionally taken on fences throughout
district.
A. megacephala. Fairly common as larva and imago.
A. rumicis. A specimen bred from larva feeding on verbena
in garden ; occasionally at sugar in Forest.
