ICERYA ROSA IN JAMAICA. 
Mr. T. D. A. Cockerell has sent us specimens of Icerya rose, R. and 
H., which were found by Dr. Strachan, of Kingston, upon the leaf of 
Amherstia. Other specimens were found upon rose in the same garden. 
For the reason that this species is known in this country only at Key 
West, we have anticipated that it would prove to be a West Indian 
form, and this sending by our friend Mr. Cockerell is confirmatory. Mr. 
Cockerell, by the way, is making a careful study of the Coccide of 
Jamaica, and has already obtained many interesting forms. 
THE PHYLLOXERA AT THE CAPE OF GOOD HOPE. 
According to recent advices Phylloxera vastatrix is still spreading 
into new territory in Cape Colony. The Agricultural Journal of the 
Department of Agriculture at Cape Town, for January 28, 1892, states 
that the only safe plan as yet known is to find out which of the Phyl- 
loxera-proof American varieties suits the particular soil, then to make 
a nursery with such cuttings and graft the susceptible European vines 
on them. Experience shows that this process is much easier in the 
South African climate than in the older grape-growing countries. The 
frequently recommended plan of growing the European vines from 
seed is once more shown to be useless. Such vines are not resistant 
to the Phylloxera. 
A NEW TREE BAND. 
The Philadelphia Record of March 3 describes a device which is said 
to have been invented by Carl Hering the well-known electrician, for 
the destruction of caterpillars which may be attempting to climb trees. 
Mr. Hering’s scheme is simply to run alternate wires of copper and zine 
around the trees at a distance of one-half inch apart. The supposition 
is that the body of the caterpillar will form a circuit between the two 
wires and that the insect will be destroyed, or at least deterred from 
climbing higher. 
A TRUE BUG DAMAGING PEANUTS IN CHINA. 
M. A. Giard, in the Comptes Rendus of the Biological Society of 
France, has published a short paper in which he reviews the damage 
done by Halticus minutus to the peanut crop in Cochin China. He 
reviews the general subject of injuries by different Pentatomide, par- 
ticularly by congeneric forms, and states that the enormous peanut crop 
of French Cochin China is threatened with absolute destruction by this 
insect. Kerosene is recommended as a remedy and the artificial culti- 
vation of Micrococcus insectorum is suggested. 
SARCOPHAGA IN THE HUMAN EAR.
