150 Carter: Hibernation, etc., of Scotosia dubitata L. 
species, like many others, hibernates during the winter months,. 
is well known, but of how many species can we say that we 
know the exact kind of situation—hibernaculum—selected ? 
So far as Scotosia dubitata is concerned, Mr. Hastings, during 
his cave explorations in various parts of the West Yorkshire 
dales, has met with this species on several occasions; and on 
January 22nd last, in company with Messrs. J. Beanland, R. 
Butterfield and J. H. Holmes, it was met with in a cave in 
Wharfedale in extraordinary numbers, indeed, not fewer than 
Cuthbert Hastings). J [ Photo. 
Scotosia dubitata on roof of cave. 
150 to 200 specimens were observed. About a dozen specimens 
were secured, and these I have had under examination, and find 
that about a third of them are males, and the remainder females, 
mostly in excellent condition, the females being especially so, so 
that it would almost be safe to assume, without actual proof, 
that pairing takes place in very early spring. At the same time 
it would add to our knowledge of the habits of the species if this 
could be proved during the coming season. The accompanying 
photographs were taken by flash-light, by Mr. Hastings. 
If Mr. Carter will keep these specimens alive in separate boxes, 
he will probably be able easily to ascertain whether the females 
deposit fertile eggs without pairing in the spring ; and as he has 
both sexes he can also endeavour to pair some of them.—G.T.P.
