opportunity of studying the habits of this species in the field 
near Glastonbury, Somersetshire. I first met with it on July 
2nd, and after a rainy interval saw it again on July 10th, 
11th, and 12th. The moth frequented a small patch of ground 
about 80 yards square, covered with heath and ling, inter- 
mingled with bog-myrtle, alder bushes, and birch trees. The 
insect was on the wing in bright sunlight from 10.30 a.m. to 
1.30 p.m. The rest attitude was first observed on July 10th ; 
when following a moth that was flying about four or five feet 
from the ground, I saw it settle upon the ling a little ahead of 
me when it became invisible. However, on closer inspection T 
found it had alighted on a thin stem of ling, with the under- 
side of its outspread wings uppermost. When disturbed it 
again took a short flight of a few yards, and settled in exactly 
the same manner. This happened during four successive 
flights of this one insect ; and for the rest of that morning 
and the following days I was interested to notice that all the 
others, which I saw settle, invariably did so in this attitude. 
The interpretation is not far to seek when a comparison is 
made between the colouring of the upper- and under-sides. In 
the former the bright purple and rich golden markings at once 
attract the eye and render this little Geometer a conspicuous 
object. The under-surface, on the other hand, possesses a 
perfect cryptic colouring of dark dull purple, combined with 
shades of tawny yellow. It should be noted that on no occasion 
was the flower itself selected as a resting-place, but always the 
leaf or stem, the dull colour of which, combined with the dark 
shadows in the interior of the plant, formed a background 
harmonising in a remarkable manner with the exposed surface 
of the insect. In conclusion, I should like to record my sincere 
gratitude to Professor Poulton for very kindly looking over 
this note.”
