lie ntiill ivalor to successfully contend against 
tdielil. ’I lie young leaves and Kose buds are 
■lioice and delicate morsels to these plant 
■iiomies, and they are remorseless, in their 
Instruction. Some gardens are relatively 
ee from the depredations of the larger 
lumber of them, bill few gardens indeed are 
Iwithout, several of the insect pests, so that 
those who would enjoy their Itosesi in list be 
watchful at all limes, especially al the com 
iiieiiceinent of the outbreak when the leaves 
are jmst unfolding until the flowers are on the 
point of expansion. In proportion to the 
watchfulness of the cultivator, so will the 
I lost is be perfectin' otherwise when they reach 
their flowering stages in dune and duly. 
The Golden or the Green Rose Chafer 
(Cetonia aurata). 
In this beetle we have a noble and hand¬ 
some enemy of the Itose, which, if it were 
at all scarce, enfomiolegists or those with a 
love, for insects, would be loath to destroy. 
I he (.olden Chafer is by no moans a common 
beetle about London, except on occasion, 
when it may bo present in thouisands in the 
western suburbs and proven real pest. If not, 
to be eradicated, d shniuihl at least be severely 
thinned in numbers. 
'I lie beetles appear during May and dune, 
settling upon the Roso and Apple blossom’ 
devouring the stamens, and thereby prevent¬ 
ing tho fertilisation of the flowers.' They are 
even more destructive to Strawberry blossom 
wnen lliov occur in vast numbers iii a Straw 
berry held or plantation. The female chafer 
busies herself in laying eggs in the ground in 
So, " e N I*,at ion where I lie larvae when hatched

si/e when full fed, and lie in the curved posi 
lion shown in I,lie accompanying illustration, 
t hey are about I Ain. long, thick, fat, and 
while, with a pale.yellow head, furnislied with 
strong jaws, by which they destroy the roots 
of a great variety of garden and oilier plants. 
The maggot is similar to that, of I,lie (lock 
chafer, hut, is furnished with transverse lines 
of short hairs on the body, by which it may 
be o isl i ngu islicd. 
The grubs live in the soil for two or three 
years until full fed, when they make 
cocoons of earth covered on the outside with 
pellets of soil, as shown in I lie. figure. In 
ibis cocoon file grub, passes into llie pupa, 
stage, as shown in the figure, and rests in the 
soil until some timi'i in May, when, it changes

Remedies. When tlu; beetles appear dur 
ing May and .June they may be calUigJit, with a 
sweeping or butterfly net, in bright, weather. 
When Idle weather is dull they are very slug¬ 
gish, and may be gathered by band, putting 
them in glass jarsi or wide mouthed bottles 
until they can bo destroyed The cultivator 
may also examine trc-cH. or bushes in the 
neighbourhood in the early morning nr in dull 
weather, and shake the beetles down on cloths 
spread beneal li 
llie, grubs can also bo trapped by laying 
pieceii of turf over Idle infested ground, heaps 
of weeds, dung, or anything containing voge 
I able mutter of wliieli the giJUibs are very fond, 
and lay up Micro where they may be caught, 
when the traps are examined. In some cases 
if may be convenient to keep poultry which 
are fond of the grubs. They are given to 
scratching, however, and it would lw safer to 
keep tame rooks and gulls, which devour smell 
gruYi in large numbers.

and a line of black spots, each bearing a 
brist le, along tin- middle of each side d lie 
head is also brownish black. I wo broods 
of these cat"i'piliars in a year torment the 
Rose grower, the lirsf in May and .linmand 
the second in August and September. 
llie female insect makes a cut, in a young 
twig and deposits an egg therein In a few 
days I lie larva batches out and comnieiu'es 
eating llie leaves, gnawing or cutting thorn 
regularly in strips of a certain breadth, until 
nothing but flic mid ribs of llie leaflets are

fioiis on flic odgo of llio leaflet, and they 
either curl their fail downwards or upwards, 
these attitudes serving to (listingiiirsb the 
particular genus at least, to which llie name 
belongs. llio accompanying illustration 
shows some of the attitudes of the cater pi I lur 
when feeding,
