meal or powder : the legs are short and six in num- 
ber. This insect continues to wander about the 
plant it infests, nourishing itself by sucking the 
juices. The male is very small, rose-coloured, 
somewhat mealy, with semitransparent milk-white 
wings, and four long filaments at the tail. When 
the female is full-grown, and pregnant with 
eggs, she ceases to feed, and remaining fixed to 
one spot, envelops herself in a fine white fibrous 
cotton-like substance, and lives but a very short 
time afterwards. The young, which hatch under 
the husk or body of the parent insect, proceeding 
from it in great numbers, and dispersing them- 
selves in quest of food. This species is a native of 
the warmer parts of Africa and America, from 
whence it has long since been introduced, among 
exotics, into Europe. 
Coccus Hesperidum is equally common in green- 
houses with the former: the female of this species 
is a small, brown, oval inject, about the sixth of 
an inch in length, of a slightly convex, smooth 
surface, and furnished with six short legs. AVhen 
full grown it does not envelop itself in any floccu- 
lent matter like the former, but remains firmly 
fixed on the bark, under the form of an oval convex 
shell or husk, of a polished brown colour. In this 
state it dies, giving birth to a numerous race of 
young, hatched from the included eggs, as in the 
former species. The male is a very small two- 
winged fly. This species of Coccus, like the 
former, has been introduced into the European 
regions from tlie warmer parts of the globe.
