entitled *‘ Diseases of the Mediterranean Orange,” in which the Rust 
Mite (Typhlodromus oleivorus), two species of Dactylopius, the Flat 
Scale (Lecanium hesperidum) and the Fruit Fly (Ceratitis citriperda) are 
specifically mentioned. Nothing new in the way of remedies, however, 
is suggested. 
SPRAYING FOR THE CODLING MOTH. 
The effectiveness of spraying against the Codling Moth is shown by 
the interesting results of a comparative test made by Mr. Waldo F. 
Brown and quoted from the New York Tribune in the American Cultivator 
for January 2, 1892. Mr. Brown carefully examined two trays of unas- 
sorted apples, each containing 100, the fruit in one tray being taken from 
a tree which had been sprayed, and in the other from an unsprayed tree 
adjoining. The apples were divided into three grades, first, second, 
and third, No.1 being perfect apples, No. 2 having one or two blem 
ishes, and No. 3 being almost worthless. In the tray containing fruit 
from the unsprayed tree there were 4 perfect apples, 58 second-class, 
and 38 culls, while the tray filled from the sprayed tree contained 84 
first-class, 9 second-class, and 7 culls. 
A NEW LOCALITY FOR ICERYA PURCHASI. 
Mr. J. W. Douglas announces in the Entomologists Monthly Magazine 
for December, 1891, that Mr. D. Morris, assistant director of the Royal 
Gardens at Kew, has sent specimens of Icerya purchasi received from 
St. Helena. They were found upon rose bushes which had been im- 
ported from the Cape of Good Hope. Mr. Douglas positively recog- 
nizes the species and recommends that the most strenuous exertions be 
made to exterminate it at once. 
THE USE OF VASELINE WITH CARBON BISULPHIDE. 
Practice has shown that the bisulphide of carbon does not give so 
satisfactory results in very siliceous earth as in others. 
Dr. Albin Meunier has been endeavoring to render this action uni- 
form by assisting the diffusion of this substance in heavy soils and pre- 
venting too rapid evaporation in those that are too light. 
The bisulphide was mixed with vaseline boiling at 350°, which is 
quite harmless to plants, even in large quantity. This diminished the 
evaporation. Though the bisulphide can be separated from vaseline by 
fractional distillation, on account of the great difference between the 
boiling points, yet its evaporation at ordinary temperatures 1s consider- 
ably diminished by the addition of vaseline, which retains consider- 
able quantities for days in spite of a considerable surface of evapora- 
tion. 
Five thousand seven hundred kilos of carbon bisulphide mixed with 
vaseline were employed in the Department of the Rhone in 1888 with
