the foliage of the white everlasting pea, the plants being quite 
ruined, and a new set of leaves and shoots were sent up and but 
poor blossom resulted in consequence. I have seen the same attack 
in culinary peas, especially in the William Hurst variety, and it 
certainly lessened the yield, although the damage was confined to 
the young leaves. Ai 
June and July seem to be the months when this Springtail is most 
abundant. In one case the damage was very noticeable in May. 
Mr. BLAKEY, writing me on the second of June this year, says the 
same species « is now on the turnips ». Probably this is the same 
as the attack recorded by Miss ORMEROD from Scotland. 
Mr. SAUNDERS reported to me a bad attack on dwarf beans 
in 1910, in Cheshire, some of the attacked plants being quite 
killed. 
Mr. BLAKEY sends the following notes from near Redditch : 
« I found the Sminthurus this year in the same garden, but they 
did not do so much damage to the beans. In the garden under my 
charge I have found them on sweet peas, turnips, radishes and 
lettuce. We grow sweet peas here rather extensively and I do a 
good deal of cross breeding. One batch was planted out early in 
April after being grown in pots. After they had been planted about 
a fortnight, I noticed some of the leaves damaged as the one sent. 
It was the leaves nearest the ground that were damaged the most. 
I thought at first it was small slugs. I had to be away for a time, 
when I came back I made a careful examination of the leaves and 
ground beneath and there found the Sminthurus by the hundreds. 
One of my garden hands was brushing the paths in the kitchen 
garden when he called my attention to a number of small insects, 
as he called them, that came out of the box edging when moved by 
his brush. I found thousands of these Sminthurus there. This was 
near the sweet peas. There were some young turnip plants on the 
opposite side, and I noticed the leaves were somewhat perforated, 
but thought it was the flea beetle which we generally get on our 
turnips, but I found in addition to the flea numbers of these Smin- 
thurus, and as the turnip plant was a fairly good material to make 
observations upon I arranged myself to watch them feed. I noticed 
they attacked the upper as well as the lower surface of the 
leaf; one would start at a certain spot, pierce the epidermis, work 
round and round; if they were browsing on the upper surface, they 
left the lower epidermis, if on the lower, vice versa. When one had 
got a sufficient area destroyed, another would come to its aid, until
