THE FALSE-SCORPIONS OF CUMBERLAND. 
G, A. and R. B. WHYTE. 
Edinburgh. 
THE only species of Chernetidea recorded, to our knowledge, 
from Cumberland previous to our visit were Chernes nodosus 
Schrank, and Odzstum muscorum, Leach. These were sent 
by the late Rev. F. O. Pickard-Cambridge to his uncle, Rev. 
O. Pickard-Cambridge, before the year 1892. The former 
(C. nodosus) was sent from Carlisle, and the latter (O. muscorum) 
was merely recorded as from Cumberland. 
We here record five species of false-scorpions, four of which 
are new to the county list—the fifth being O. muscorum. 
Cheiridium museorum Leach. 
This very small species was obtained in five different barns 
near the head of Derwent Water. One hay-loft is worthy of 
special note, for in it we discovered a colony, the numbers 
of which exceeded our counting powers. We took over sixty 
specimens from one stone, on which there were innumerable 
nests. A few young, never more than three at a time, were 
found in them. The actual habitat of C. museorum was under 
loose stones, which lay on the top of the walls close under 
the roof. Some moults and one or two living specimens were 
obtained by sifting dust and hay-seed from the dark, un- 
disturbed corners of the loft. We watched with interest an 
adult Chezridium museorum feeding on a mite. The mite 
was held firmly in the chelicerae, and the life-juices were 
sucked out. 
Chernes rufeolus Simon. 
We found a single specimen of Chernes rufeolus on April 
11th, and a week later obtained many more. This rare false- 
scorpion was found under the stones set fast in the earth 
floors of three old barns. The nests were also obtained, and 
proved to be of this species by the moults inside them. 
C. rufeolus has only been obtained in a few of the southern 
counties in England, and never in Scotland, so that this is the 
most northerly record for Britain. 
Chernes dubius Cambridge. 
This species, which is smaller than its congener, Chernes 
rufeolus, was discovered in some numbers under stones firmly 
embedded in the soil, both in the woods and in the open 
country, south of Derwent Water. It is a chernetid which
