unexpanded buds, at the same time covering them with a 
kind of sticky globules, popularly, but wrongly, described a 
“honeydew.” This secretion, together with the excre- 
ment, quite prevents the buds from developing, especially 
if the season be a dry one. Between the deposition 
vf the egg and the emergence of the perfect insect 
about a month elapses. During that time the larva 
changes its skin five times. At the end of the third 
moult the wings are plainly discernible, as shown in the

illustration (Fig. 67). In the mature insect the wings 
are disposed roof-like, as shown in the illustration (Fig. 67). 
Those perfect insects which are to carry on the cycle 
of existence pass the winter under the bark of the 
tree. 
Trees which are attacked soon show unmistakable 
symptoms. The foliage assumes a most unhealthy yellow- 
ish-green colour, and not infrequently prematurely falls. 
The blossom-buds also fail to set, and are shed in 
quantities. 
By way of remedies the grower must depend entirely 
upon spraying, for which there is nothing equal to weak 
kerosene emulsion. This should be applied in April, 
directly the leaves show signs of opening. Several 
applications may be necessary throughout the season, for 
so far as at present is known the eggs are impervious to 
what may be termed safe insecticides. As an additional 
precaution the trees should aiso be similarly treated in 
winter, and all prunings should be burnt. 
APPLE-TREE CANKER. See Canker. 
APPRESSED, ADPRESSED. Lying close, e.g., 
leaves Appressed to a stem. 
APRICOT. To the varieties described in Vol. IL, 
pp. 99-100, the following may now be added : 
Alberge de Montgamet. A smull, early, hardy, and prolific 
variety. Fruit deep yellow, fair flavour, and one of the best for 
preserving. Ripe at the end of July. 
Beaugé. A late and good form of Moorpark. Ripe middle of 
September. 
Apricot—continued. 
D’Alsace. A glorified form of Moorpark. The fruit is larger, 
and equally as highly-flavoured. The tree is a vigorous grower, 
and not so liable to die away as Moorpark. 
Early Moorpark. An early variety that ripens its fruit three 
weeks earlier than the original Moorpark, to which it is similar 
in growth and fruit. Ripe early in August. 
Frogmore Early. Fruit small, deep orange in colour, with a 
good-flavoured flesh. Ripe early in July. 
Golden Drop. One of the most delicious in flavour, with a rich 
melting flesh, Fruit small, deep orange in colour. As the trees 
acquire age they become very prolific. Ripe at the end of July. 
Hemskerk. Somewhat similar to Moorpark, but the tree is 
hardier and more enduring. Ripe early in August. 
La Délicieuse. A new variety from the East, stated to be of 
exquisite flavour. 
Large Early. Fruit large, deep reddish-orange colour; flesh 
tender, melting, and richly flavoured. Ripe at the end of July. 
New Large Early. A very early form of the Large Early. 
Oullin’s Early. An improved early form of Peach, but of larger 
size and exquisite flavour. An excellent free-bearing variety. 
Pine Apple. Fruit large, deep yellow on the shaded side, and 
rich red cheek on the exposed side; flesh very tender, melting, 
and juicy, with a pleasing Pine-apple flavour. Ripe the 
middle of August. 
Powell’s Late. Fruit deep orange, flushed with red, large and 
abundantly produced ; flesh sweet, juicy, and delicious. One of 
the hardiest and best varieties. Ripe early in September. 
Roman. Fruit large, deep yellow, of brisk flavour; useful for 
preserving. A good bearer. Ripe the middle of August. 
APRICOT WEEVIL, or RED - LEGGED 
GARDEN WEEVIL (Otiorrhynchus tenebricosus). 
If not as frequently met with in gardens as some of its 
near relatives, yet it is so destructive thet every gar- 
dener should be familiar with it. Moreover, in certain 
parts of England (the south) 
it is a fairly common hedge- 
row insect. -In the perfect 
state, this Beetle attacks 
all parts above’ ground 
of such trees as Apricots, 
Peaches, Nectarines, <&c.; 
while the grubs sometimes 
damage the roots of Rasp- 
berries, Strawberries, and bush 
fruits like Currants. The 
Beetle (Fig. 68) is 3in. long, 
black, and covered with yel- 
lowish down. The legs are 
red. 
Being nocturnal it is not 
often seen, for in the day-time 
it secretes itself in wall cre- 
vices, under rubbish, &c. 
Where its presence is sus- 
pected, the trees should be 
visited at night and shaken over a tar-covered paper. 
Like most other Weevils, this one drops readily on being 
disturbed, when it may be picked up ‘and thrown into a 
vessel of boiling water. The necessity for filling up 
eracks and wall crevices will be obvious. See also Otior- 
rhynchus. 
APTERA. This is one of the Natural Orders 
into which naturalists divide the important Class Insecta. 
The insects belonging thereto are very minute, soft-bodied 
creatures, destitute of wings, and with the mouth either 
mandibulate or imperfectly suctorial. The Order is again 
sub-divided into Thysanura and Collembola. None of the 
members of either sub-order call for extended notice, for 
though commonly found associated with garden produce 
they are perfectly harmless. Indeed, they may almost 
be considered useful scavengers, feeding as they do on 
the lower animal and vegetable life. The most familiar 
insects of the Order are those members of the Collembola 
which are capable of leaping, and on that account are 
popularly known as Springtails. 
APTOSIMUM. The correct name of Ohlendorfiia 
(which see).
