apple-leaves; the larva, when hatched, 
mines in the upper cuticle, and usually 
in the direction of the stem, forming a 
slender track, which turns pink, and be- 
trays the presence of a larva in the leaf 
before it is visible to the naked eye ; this 
track is frequently close to a rib; as the 
mine becomes wider it is orange-coloured, 
with irregular tracks of brownish excre- 
ment: it is never very conspicuous from 
above, but quite invisible on the under 
side ; after a lime the larva commonly 
doubles on its track, and forms a blotch, 
from which it emerges on the upper side 
to wander away and form its cocoon. The 
larva is very shining, orange-coloured, 
with dorsal vessel only' slightly darker; 
head pale chestnut. The cocoon varies 
from dark chestnut to bright orange: it 
is slightly mussel-shaped, and always has 
a rim of much brighter hue round the 
upper end, which gives it a striking ap- 
pearance; the pupa is protruded on the 
escape of the perfect insect. The imago 
expands about three lines, and is of the 
unicolorous group ; the anterior wings 
cinereous, glossy, and with a purple hue, 
brightest towards the apex ; the posterior 
wings of an uniform paler colour; head 
rufous with whitish eye-caps. In the 
perfect state it is closely allied to P///;- 
iTueella. It is double-brooded, appearing 
in May and August, the larva occurring 
in July, October and November; the 
.Tilly larva seems very scarce, — I observed 
them this July for the first time; the 
autumnal larvae are by no means rare in 
the neighbourhood of Bristol. — P. H.
