314 LINCOLNSHIRE NATURALISTS AT WOODHALL SPA. 
C. pygmaeus were also found, together with the variety semzstriatum 
of Spheridium bipustulatum with distinctly punctured striz on the 
elytra. Geotrupes spiniger was found here at an average depth of 
about four inches, owing to the hard nature of the ground. Under 
the loose bark on the fallen trunk of an ash-tree lying across the 
dyke Mycetophagus piceus was very abundant indeed. In colour it 
exactly matched the decaying wood, and the beetles seemed to be 
fully aware of the fact, and remained perfectly still until just as you 
were going to pick them up, and /fen livelier specimens could hardly 
be imagined, and if two commenced to run at the same time one of 
them was almost sure to escape. Proceeding along the wood side 
and crossing a small dyke in which Ve/ia currens was about the only 
visible sign of animal life, we came to a couple of ponds in a semi- 
dried up state. Loricera pilicornis was abundant round the edges, 
great speed and the boggy state of the pond edge. Here the soil 
became much looser, and several Geotrupes stercorarius were dug up 
from a depth of about twelve inches. A nest of ants with the winged 
males and females clustering round the outside was here seen, and 
then the time for tea arrived and a hurried return had to be made 
for the Eagle Hotel. Needless to say, the Swallow-tail Butterfly, 
once common in the swamps and by the river-side, was at obtains: 
Owing to the very dry state of everything, ‘stone-turnin 
of very little use, the only captures being Xantholinus ‘julviduss 
Harpalus eneus, Pterostichus madidus and P. niger, Calathus melano- 
cephalus, and under some stones in a dried up pond Agabus guttatus 
and A. dipustulatus.
