petioles. Pseudo-bulbs one- or two-leaved. The species 
here described should be grown in baskets suspended from 
the roof of the cool-house. Peat and moss form the most 
suitable compost; and abundance of water during the 
growing season is essential. Propagation may be effected 
by division of the psendo-bulbs. 
GC. miniata (scarlet). This is supposed to be a natural hybrid 
between @. Noezliana and Cvulcanica. (L. 1897, t. 562.)

COCHLOSPERMUM. Azeredia, Mazimiliana, and 
Wittelsbachia are synonymous with this genus. 
COCKCHAFERS (Melolontha vulgaris). These well- 
known Beetles seem to be on the increase, or perhaps their 
depredations are oftener brought home. As stated in Vol. I. 
they are most undesirable insects in the garden and park ; 
but they are equally objectionable in the orchard and on 
the farm. As Beetles they feed upon the foliage of nearly 
all our deciduous shade-trees, as well as upon various frnit 
trees; while as grubs they are notoriously destructive to 
grass roots, corn roots, the commoner field crops grown for 
their roots, nursery beds containing seedlings, and even 
upon Strawberry-roots. On the Continent, more particu- 
larly in France and Germany, the Fir plantations suffer from 
their ravages, and, with all the insecticides available, man 
is largely dependent upon the birds and the bats for pre- 
te the requisite balance, especially in the case of grass 
and. 
_ In addition to the methods for their destruction recorded 
in Vol. I., gardeners and farmers should try beating the 
trees in infested districts over tarred boards. This is best 
done early in the day, when the pests may be found on the 
under-surfaces of the foliage. They are readily dislodged 
and should be collected and destroyed.

COCKROACHES are Orthopterous insects, doing much 
damage to fruits under glass, choice flowers (like Orchids), 
the fronds of Ferns, and many other plants. In vineries 
they are exceedingly troublesome at times, feeding upor
