‘1 never observed before ». The correspondent later wrote : « Not 
only the first two leaves were eaten, but the rough leaf was also 
attacked », and he described the pests as being a dirty yellow 
colour, and also black. « They jump on being approached. So 
numerous were they in one field that they rose before one like 
a little cloud. » 
Miss ORMEROD identified one as S. luteus and assumed the dark 
species to be S. niger. 
In Cheshire, one of my old students, Mr. SAUNDERS, biologist 
at Harper Adams Agricultural College, noticed damage done to 
young turnips in 1909 and 1910 by Springtails. They eat out round 
holes in the seed leaves similar to the attack of turnip flea beetle. 
He found the same insect common on Polygonum and other 
weeds. Although they did little actual damage, they were noticed 
to feed in a most persistent manner. 
He informed me they had been identified as Sminthurus 
hortensis. 
Sminthurus pruinosus TULLBERG attacking beans and sweet 
peas. 
The damage done by this dusky Sminthurus was first noticed by 
Mr. BLAKEY of Redditch, and some of his notes are included here. 
The damage to bean leaves (fig. 8) seems somewhat different to 
that done to sweet pea foliage (fig. 9). In the former, the leaf is 
characteristically eaten away in small areas which may later split 
into larger spaces, as seen in the photograph of a french bean leaf 
taken by Mr. BLAKEY. 
In sweet peas the leaves are eaten in larger patches of longer 
form, as seen in figure 9. 
I have not seen the attack on french beans (fig. 8), but the 
attack on sweet peas is very common, and usually starts on the 
lowest leaves, and gradually the attack works upwards. 
This dusky Springtail (fig. 10) also attacks turnips in a similar 
way. It is just as shy as S. luteus, but if one proceeds carefully, it 
can be watched feeding on the under side of the foliage. 
The young are not very active, and are paler in colour than the 
adults and may easily be seen on the lower surface of the leaves, 
whilst the adults skip rapidly away. 
In one case observed on peas, considerable damage was done to
