clods of earth. The damage done was very severe, and immediate 
steps were taken to clear the Aptera out (1). 
A Podurid sp. ? attacking mushrooms. 
One of the Poduridæ was reported to me in 1908 as being very 
harmful to mushrooms in the caves of the North Downs Mushroom 
Company, near Reigate. The mushrooms were covered with them, 
and they gnawed the skin, and so not only spoiled great numbers 
for market, but actually ruined laree numbers. Many of the attack- 
ed fungi were deformed in very marked manner. 
Watering the beds with nicotine before the mushrooms appeared 
above ground seemed to be successful. 
nem erowers use lysol as a means of destroying insects in 
mushroom beds. 
/sotoma tenella REUTER destroying tobacco is 
in Ireland. 
This small dark greyish Collembola has been recorded by 
CARPENTER (2) as occurring in multitudes on seedling tobacco 
leaves at Kilkenny in Krane 
The surface ofthe leaves showed distinct abrasions, and CAR- 
PENTER found that the digestive tracts of the Aptera contained 
chloroplasts. 
This species was first described from Finland, later 1t was found 
in Germany, and then by CARPENTER as a destructive insect in 
Ireland. 
They were easily killed with a nicotine fumigator in spite of 
their feeding on tobacco.
