INSECTS IN THEIR RELATION TO FLOWERS. 149 
23.—March 15, 1882. Westley Wood, Saffron Walden. A 
male specimen of Anthophora acervorum paid five visits to Primula 
vulgaris and was then lost. Endymion nutans and Ranunculus 
ficaria grew around. 
24.—March 19, 1882. Fox’s Wood, Great Bardfield, Essex. 
Ranunculus ficaria grew in great abundance in an open part of the 
wood, mixed with a few other species. A small tortoiseshell 
butterfly, Vanessa urtice, visited it 19 times, then settled on the 
ground and afterwards flew away. 
25.—April 10, 1882. Meadow at Great Bardfield. An 
individual of Anthophora acervorum visited consecutively 108 
flowers of Primula elatior (which was abundant), rejecting many, 
but without even hesitating at the flowers of any other species, 
although quantities of Ranunculus ficaria grew on the same spot, 
and Cardamine pratensis, Bellis perennis, Ranunculis acris, Nepeta 
glechoma, Leontodon taraxacum, &c., were out close by. 
26.—April 11, 1882. Avesey Wood, near Thaxted. Primula 
- _ elatior and violets (Viola? canina) in very great profusion inter- 
mixed, but no other species of any importance. Plenty of hive- 
bees were visiting both species, but I did not observe any change 
from one to the other. 
27.—Same date and place. An individual of Bombus scrim- 
shiranus which I watched seemed to be visiting flowers of P. 
elatior and Viola canina one after another, apparently with 
perfect indifference. 
28.—Same date and place. An individual of Anthophora 
acervorum which I watched did exactly the same as the last bee 
mentioned. 
29. — April 11, 1882. An open part of Grassy Wood, 
Wimbish. I watched many hive-bees visiting flowers of Primula 
elatior, Viola canina, Ranunculus ficaria, and Mercurialis perennis 
(all of which grew in abundance), but did not see one single 
instance in which a bee changed from one species to another. 
30.—Same date and place. A _ hive-bee visited Primula 
elatior 23 times, having avoided all else when I caught him. 
31.—Same date and place. A sulphur butterfly, Gonepteryx 
rhamni, visited Primula elatior 3 times and departed, having 
passed over ail else. 
32.—May 11, 1882. A cut-down wood immediately behind 
Chelsfield Station, Kent. At one spot Galeobdolon luteum,
