Hewitt has reviewed the habits of one of the species 
known as Chemes nodosus Schrank, which, he states, 
is more abundant in England in some years than in 
others. He quotes Godfrey (1909): “The ordinary 
habitat of Cherries nodosus, as Mr. Wallace Kew has 
pointed out to me, appears to be among refuse, that is, 
accumulations of decaying vegetation, manure heaps, 
frames and hotbeds in gardens. He refers to its occur¬ 
rence in a manure heap in the open air at Lille, and 
draws my attention to its abundance in a melon frame 
near Hastings in 1898, where it was found by Mr. 
W. R. Butterfield.” Doctor Hewitt very justly calls 
attention to the fact that it is not difficult to under¬ 
stand the frequent occurrence of this false scorpion 
on the legs of flies, in view of the facts just quoted 
from Mr. Godfrey, since flies frequent such rubbish 
heaps for the purpose of laying eggs, or he suggests 
that when they have recently emerged from puparia 
in such places and are crawling about while their wings 
are drying their legs are readily to be seized by the 
Chernes. In closing his account of this species he 
writes, “It is obvious that the association [between 
the Chernes and the fly] will result in the distribution 
of the pseudoscorpionid, but whether this is merely 
incidental and the real meaning lies in a parasitic or 
predaceous intention on the part of the Arachnid, as 
some of the observations appear to indicate, further 
experiments alone will show.”
