I have seen half a dozen or more on one spot. From what I can see 
this pest is increasing very much and ought to be looked after, and 
if they shelter in such places as box edging, it ought to be sprayed 
or dusted with some material that will destroy or make their habit- 
ation untenable. I have been in the habit of using vaporite for soil 
pests. In this case, instead of using it in the usual way, i. e. dry, I 
dissolved some in hot water, then diluted 1/4 Ib. to 4 gallons, 
watered the plants and surrounding ground with a fine rose can. 
This seems to be effectual. No doubt other things would answer 
the purpose. » 
An attack of Sminthurus sp.? on mangolds was noticed by 
Mr. SAUNDERS in 1909 in Cheshire. 
In 1908 the same Springtail attacked maize. The young plants 4 
to 18 inches high were attacked in July. They ate out longitudinal 
holes between the veins, much as in the damage done in peas. 
The attacked maize sent me showed markedly twisted and 
deformed leaves, and the whole growth was said to be stunted. 
Little harm was done after August, and the crop was only 
slightly below the normal. Another, but slighter attack, followed 
in 1909. Mr. SAUNDERS informed me that the species was identified 
for him by Mr. COLLINGE as Sminthurus hortensis.

The following note occurs in « Insect Life » (1): 
« Sminthurus hortensis. These active little insects were extre- 
mely abundant in Indiana the present season. 
» About La Fayette I observed them feeding upon young cucum- 
ber plants, the injured parts of plant not being affected by other 
insects or fungus. 
» They were also reported by Mr. C. G. BOEMER as injuring 
young tobacco in Switzerland County during the month of May. »
