which have about twenty small black spots, the cilia a similar colour 
to the wings ; posterior wings grey, the fringe uniformly grey, thus 
differing from H. pculellci, in which the fringe of the posterior wings 
is pale grey or white with grey apex. 
The moths appear in July and August. The earliest record I have 
of them is July 4th and the latest August 10th. Whitehead says 
they appear towards the end of June. I have never observed them 
as early as this. Those sent by Mr. Bear were taken on August 2nd. 
Mr. Bear’s note, p. 31, being quite a new observation and by no 
means an unimportant one. As in all this genus the female deposits 
her eggs on small twigs, in circular patches about one and a half lines 
in diameter ; these egg masses are then covered over with a glutinous 
substance which is at first yellow, but which gradually becomes 
brown, until they resemble the colour of the bark upon which 
they are situated. They are laid in groups of fifty to eighty ; they 
are placed in rows which overlap one another like tiles. These eggs 
hatch in the autumn and the minute larvae remain under this case, 
now composed of a glutinous substance and the debris of egg shells. 
As many as two to six dozen larvae form each group and there they 
remain all through the winter. They are at first of a pale yellow 
colour with black head and dark succeeding segment and vary in 
length from one-half to two-thirds of a line. As soon as the buds 
begin to burst these little larvae escape from the nest and enter the 
expanding buds and can then be easily found. In May they seem to 
disappear, but have mined their way into the soft parenchymatous 
tissue of the leaves, leaving the epidermis untouched. During this 
period they cause the leaves to become red in patches and later to 
become brown owing to their tunnelling into them. As a rule about 
a dozen occur in each group on the leaves. As soon as the miners 
are sufficiently strong they leave the protection of the leaves and 
feed upon them. They may also be found in the developing calyces 
of the blossoms and feed upon them. At first they retain their 
yellow colour, but after becoming free they gradually become a dirty 
ashy grey colour spotted with black, and later the ground colour 
becomes dull yellowish leaden-grey with more prominent black spots. 
Soon after they vacate the blossoms and leaves and they become 
gregarious and live for the rest of their larval existence beneath 
a nest of grey silk spun at first between the folds of a leaf or 
leaves and later between the twigs. The small leaf nests are found 
in May. By June they make large nests and are nearly mature, and 
towards the end of the month they spin delicate cocoons often side 
by side in the nest in which the larvae pupate and from which the
