purely accidental, I suppose the lady-bird to have been poaching 
for Aphides. 
The family Histeride have their habitat in dung, and four 
of them are found in ants’ nests. 
Among the Lamellicornia there are none, and although many 
of these insects act as scavengers, their comparatively large size 
will quite account for their absence. The larger ones could not 
get into the nests without breaking a passage, and the entry of 
even the smaller ones would prove inconvenient. 
Among the Malacodermata only one, Ptinus sexpunctatus, in 
the nests of humble bees. 
Of the Longicorn beetles, the Chrysomelide and the weevils. 
there are altogether more than eight hundred British species ; 
they are all vegetable feeders and none are found associated 
with Hymenoptera. 
I think therefore that until some better reason is forthcoming, 
we may assume that, where these intruding insects are apparently 
_ neither enemies to be attacked, nor friends to be protected, they 
are simple scavengers, whose presence is tolerated. 
Well Boring at Bitton. By H. H. W1inwoop, M.A., F.G.S.

Your President, at the beginning of the past year, called my 
attention to a well boring in his parish at Bitton. As it is 
important that every detail of the rocks beneath our feet should 
be recorded, and as there are some facts of interest, besides those 
relating to the water question, connected with this boring, I have 
ventured to bring these notes before the Members of our Club. 
The site of the bore is in the midst of Messrs. Somerville’s Paper 
Mills, on the 50’ contour line, in the Golden valley at Bitton ; 
the object was to obtain an increased supply of water for 
manufacturing purposes. During the year I paid several visits
