Mr Cambridge records from Scotland without specifying the 
exact locality ;! and O. ephippiatus (Koch) has been recorded 
from Argyll by ourselves. O. Meadii, Cambr., is a species 
apparently confined to the south of England. 0. spinosus 
(Bosc.) has been found in the south and midlands of England ; 
and abroad it is also a species of southern distribution 
occurring in France, South Europe, and North Africa. The 
general southern range of these last two forms, as well as 
their tolerably conspicuous appearance, renders it probable 
that they are not to be found in our district; while 0. 
cinerascens and O. ephippiatus, though probably present, could 
hardly have escaped our notice were they at all common. 
In his “ Monograph on the British Species of Chernetidea, 
or False-Scorpions,” published in 1892, the Rev. O. P. 
Cambridge enumerates twenty species, most of which he 
characterises as rare even in the south of England, and 
no Scottish localities are given, unless “near Berwick- 
on-Tweed” — whence he has received Chelifer latreillii, 
Leach—refers to one. In Scotland we have only found 
two species, namely, Obisitwm muscorum, Leach, and 
Chthonius rayi, L. Koch, the former alone having been 
obtained in the Edinburgh district, where, however, it is 
tolerably common. Others, no doubt, occur, but we are 
inclined to think that the number of species which range 
north of the Tweed is very small. Chiridiwm museorum 
(Leach) should be looked for in old books and herbaria ; * 
and collectors of our Diptera will do well to bear in mind 
that another species, Chernes nodosus (Schr.), which has been 
taken as far north as Yorkshire and Carlisle, is usually found 
adhering to the legs of flies. 
The arrangement and nomenclature of the present list are 
in keeping with the two “ Monographs” by Mr Cambridge, 
mentioned above. 
1 Since the above was written, Mr Cambridge has kindly informed us 
that specimens of this species were sent to him from the neighbourhood of 
Glasgow by Mr H. C. Young, and from the valley of the Tweed by the 
late Sir W. Elliot. 
2 [ am nearly certain I once saw this creature, the tiny ‘‘ Book-Scorpion,” 
in my herbarium, but not being at the time specially interested in the group, 
I unfortunately did not think of preserving a specimen.—W. E.
