Insects in Great Britain.

patches on the standard and a purple tip to the keel, not pure 
white as stated in Trans. Bot. Soc. Edin., xviii. 391 ; but it is 
whiter and larger than the usual form of the Eastern Alps. 
The colour varies from this creamy white to a pale lemon- 
yellow or a pale violet. The flower has a sweet scent and 
abundant honey. The calyx-tube is 7 mm. long, and its teeth 
an additional 2 mm., and is rather thin, so that it offers but 
little resistance to the insects which rob the honey by biting 
through it. The narrow part of the flower is 10 mm. long. 
The passages to the honey between the bases of the stamens 
are very long. The stigma stands 1 mm. above the stamens, 
and is touched by its own pollen. Rubbing appears to be 
necessary to make it receptive. The rough areas on the 
petals, which afford a foothold to insects, have been fully 
described by Loew for O. pilosa (Flora, 1891, p. 84). In 
plants from Clova they are distributed as follows : standard 
very smooth below, less so above on the inner face ; wings 
very rough on the surface directed upwards, especially towards 
the interlocking processes ; keel slightly rough on both sides 
towards the tip, perfectly smooth below, and rather smooth 
along the middle line. The plant fruits very freely.

attainable to all the Bombi, but not readily to Apis ; rare at 
Clova. The calyx is sometimes bitten through. The tubular 
part of the flower is 5-6 mm. long.
