238 Address to the L.incolnshive Naturalists’ Union. 
To really understand the Natural History of our County, 
we must, bearing in mind its position, study its Geology, its 
Physiography and Climatic conditions, and interpret their 
relations to its existing fauna and flora; and having done this, 
we shall, by our united efforts, have contributed something that 
will help to solve problems of the deepest scientific interest. 
A little point illustrative of this occurred on the occasion of 
our visit to Scunthorpe last year:—We found on the sandy 
warren specimens of Calathus mollis and a colony of Broscus 
cephalotes. Both of these beetles are curiously associated with 
sandy areas and almost always found on the sea coast. They are 
both found commonly at Cleethorpes, where the latter species 
establishes itself in colonies, and the heads of the beetles are to 
be seen just protruding from the burrows ready to drag in any 
passing insect. 
Now neither of these species flies, and we must look upon 
them as definitely established on these Scunthorpe sand-dunes. 
How have they come to be stranded so far from the coast ? 
Mr. Peacock gives what I consider the true explanation. He 
suggests that we may regard them as having travelled with the 
slowly moving sand-dunes from their old home in the semi- 
marine or estuarine conditions of the Trent Valley (for we 
know that these dunes have travelled S.W. to N.E. till they 
came to the foot of the Lincolnshire Limestone Escarpment) 
and that the flora has travelled along with the blown sand. 
The Coleopterist so associates in his mind these two species 
with the sea-shore that he is at a loss to explain their presence 
so far inland, and immediately invokes the knowledge of the 
Geologist and Botanist. 
Since our Union was established in 1893, much really good 
work has been done, and, year by year, we get to know more of 
the wonders of nature around us. Of late we have devoted more 
attention to Entomology, a great achievement being Mr. G. W. 
Mason’s published List of the Lepidoptera of Lincolnshive: 
this, with the Rev. E. A. Woodruffe-Peacock’s Check List of 
Lincolnshive Plants, will always be a great boon to students, in 
this county at any rate, so closely are the flora and insect fauna 
related.
