REMINISCENCES OF A VOYAGE TO AND FROM CHINA. 143 
about 1790 ; but from its being plentiful on crab-trees, nearly in the 
centre of the kingdom a few years afterwards, it is likely to have been 
brought long before. The apple-trees at St. Helena, were, in 1794, 
quite eaten up by the Eriosoma. The same insect, or a species of it, 
attach themselves to the roots of stocks and worked apple-trees in 
public nurseries; and there do extensive damage if means be not em¬ 
ployed to extirpate them. An insect of similar appearance and habits 
is~often met with on the roots of dandelion, endive, and lettuce, and 
especially 011 those of old plants. 
Another family of the gardener’s pests, are the coccid^e. Generic 
character: Snout only in the female; icings in the male, but no wing 
cases ; female wingles . 
1. Genus dorthesia, Bose, are scale bugs; the body is covered by 
a number of cottony or waxy laminae, which partly cover each other, 
and are arranged usually in a triple series. In character and habit 
allied to coccus. 
2. Genus coccus. These are also scale bugs, having a snout bent 
under the breast; antennee thread-shaped ; abdomen of the male with 
two long bristles ; wings in the males two, erect; females without 
wings. 
These insects infest the pine-apple plant, occasionally peach-trees, 
and grape-vines; orange-trees, and almost all hothouse and greenhouse 
plants, having firm and durable foliage. Sometimes one species of 
them is seen on the smooth bark of pear-trees, and on that of the 
black willow, and young ash-trees in woods.

MISCELLANEOUS INTELLIGENCE. 
Reminiscences of a Voyage to and from China (continued 
from page 103.)—We left Pulo Penang, and proceeded eastwards 
toward Malacca. This passage, through a narrow sea, was most in¬ 
teresting. On the left hand, the kingdoms or principalities of Queda, 
Malayo, and, more in advance, Siam, were covered with luxuriant 
vegetation to the water’s edge. To the right, the extensive and thinly- 
inhabited island of Sumatra was distinctly seen, and, like the opposite 
shore, was thickly covered with continuous jungle and lofty woods. 
The navigation was tedious, and the weather very unsettled: violent 
squalls and thunder-storms were succeeded by dead calms ; and as the 
ship met, or was carried out of the safe channel by various currents.
