they have a habit of leaving that to attack living wood, and 
estates in which rotten wood is allowed to lie about unnecessari- 
ly are very liable to attacks from this group of insects. 
The Longicorn beetles with oblong or cylindrical bodies and 
long slender recurved antennae, are all wood-borers. They are 
often of very large size, and are sometimes very troublesome. 
The grubs are long, cylindrical flattened insects without legs and 
live in burrows in timber, which are usually filled with the powder 
of remains of the wood they have eaten. I have not as yet met 
with any injurious to living trees here, but they are often very 
destructive to house timber. 
The Leaf-beetles ( Chvysomchdce. ) rounded thick and curved, or 
oval and flat, often gaily coloured, and usually quite small, are 
generally found on leaves which they eat. I have seen but few 
on plants Cultivated for use* but several are troublesome on our 
ornamental plants, orchids, aroids, etc. 
The useful beetles belong to the carnivorous groups. Carabidce , 
of which the tiger beetles which abound on sandy paths, flying 
briskly about for short distances at a time, are the commonest, 
They feed on Other insects. 
The other carnivorous group of importance is hat of the 
Lady-bird, Coccinelidce, of which we have several species, which 
eat the plant lice and green flies (aphides) commonly known as 
blight. The beetles are red or yellow with black spots, the larvae 
are oval or long soft-bodied insects which creep about on the 
leaves and devour the blight. One species is often to be seen 
on Coffee, when there is blight about. Of course these 
insects must be carefully protected. 
The true bugs, Hemiptera, are known by the long -pointed beak 
generally carried when at rest in a groove or merely along the 
under surface of the thofa*. Besides the true bugs large often 
gaily coloured animals with a very foul odour, the group includes 
the plant lice Coccida?. Aphides and Scale insects. The greater 
number are very injurious, sucking the juice of plants with their 
long beak, such are the rice-sapper, Leptocorisa and Dysdercus , 
but a few are carnivorous attacking caterpillars and other in- 
sects ; one of these is described below as destroying the beehawk 
caterpillars on the Coffee. The Cicadas, well known to all here 
from their noisy songs and commonly called here by the ridi- 
culous name of tree-beetles, confining themselves to the forests, 
seldom injure the planter. A curious woody swelling very com- 
mon on the boughs of Serayah trees (Shore ci Uprosula ) is caused 
by the presence of the eggs of some species of Cicada, whicli 
appear to be deposited in the bark. Ibis is very injurious to 
young trees. The larvae however live in the ground after hatch- 
ing and feed on tree roots. 
The Orthoptera include a number of injurious insects in the 
form of grasshoppers, locusts, crickets, and mole-crickets. The 
first three groups devour leaves, and often cut down seedlings 
in the nursery beds, and as many work at night, only hiding in 
holes in the ground or under logs and rubbish during the day,
