Whe San Jose Scale. —Entomologists 
A still continue to discuss the question 
of the introduction of this member of the 
Coccidae into Britain. Mr. Fred. V. Theo¬ 
bald, M.A., F.E.S., Zoologist to the S.E. 
Agricultural College, Wye, describes the 
insect in its different stages, mentions the 
trees it attacks, and explains the effectual 
method of destroying it, in a small pamphlet 
of some twelve pages. Concerning its im¬ 
portation to this country he has no doubt 
whatever, but with regard to its being able 
to withstand the rigours of this country he 
is like the Scotchman who is credited with 
saying “ I hae ma doots.” The scale has 
appeared in this country adhering to the 
fruit of Pears ; but unless the skins of these 
happen to get thrown about in the neigh¬ 
bourhood of fruit trees the danger of infec¬ 
tion would not be great. A greater source 
of danger lies in the introduction of fruit 
trees, stocks or ornamental trees and shrubs 
from the United States or Canada. In 
such cases the plants must be disinfected 
before they are planted out. Even if our 
climate is too severe for the insect to live 
out of doors, there is the chance that it 
might get established in hothouses like the 
scales of Orange trees, Camellias, &c. 
Gardeners being well acquainted with 
the sales infesting those subjects as well as 
of Peach trees and Ferns, have a pretty 
good idea of the appearance of the threaten¬ 
ing intruder, for all scales have a family 
likeness. The eggsare laid below the body 
of the mother in autumn as a rule, and these 
hatch out in spring liberating small, six¬ 
legged, active larvae, which ramble about 
over the trees in quest of a position on 
which to settle down. Their beak or pro¬ 
boscis is inserted in the bark of the tree, on 
the midribs of the leaves and on the 
developing fruits; then the females lose 
their legs, antennae, &c., and become
