withered. It will be noticed that all the flowers visited were red, 
and that although the Antirrhinum and Nasturtium were visited 
alternately, the number of consecutive visits paid to the former 
were (with one trifling exception), always greater than to the latter. 
4,—Sept. 18, 1881. On a flowery roadside bank near Audley 
End, Essex, I watched a bee of the same species as the 
foregoing. It paid 46 visits to Thymus serpyllum, 6 to Lamiwum 
purpureum, 4 to thyme, and was then missed, but half a 
minute later the same bee visited Lamiwm purpureum 10 times, 
Thymus serpyllum once, a yellow Hieracium 5 times, Lamium 
purpureum 4 times, Lamiwm albwn twice (buzzed round Urtica 
dioica as if looking for flowers), LZ. purpureum 19 times, L. album 
once, L. purpurewm 16, and then flew away altogether. This bee 
therefore paid 114 visits to four species of flower, of which two 
were reddish, one white, and one yellow. The number of visits paid 
altogether to each species is as follows:—T’. serpyllum 51, 
Lamium purpureum 55, L. album 3, and Hieraciwm 5. This 
certainly does not show much method. 
5.—Same date and place. A smaller, darker bee, but other- 
wise much the same as the last, visited Lamium album only, 49 
times before being lost sight of. 
6.—Same date and place. A bee of the same species visited 
Lamium album 31 times and was lost, having avoided all else. 
7.—Same date. JRailway-bank, near Saffron Walden. A 
large humble-bee visited 5 flowers of Senecio jacobea, 1 of 
Centaurea nigra, and 1 of S. jacobea, and was lost. 
8.—Same date and place. A smaller bee passed, with only a 
momentary hesitation, some flowers of S. jacobea and Hieracium, 
but afterwards visited 5 of Centaurea nigra, 1 of S. jacobea and 
was then lost. 
9.—Same date and place. Another bee of the same species 
visited C. nigra six times in succession, and was lost. 
10.—Same date and place. This observation was made on a 
most industrious but unmethodic bee of the same species as the 
last. It visited the following flowers the following number 
of times:—Senecio jacobea 22 (many being however the same 
flower twice visited), Hieraciwm 1 (passing a Ranunculus (? bul- 
bosus) with only a momentary glance), S. jacobea 43 (many 
of them on plants already visited more than once), took a short 
flight and inspected several flowers of Ltanunculus bulbosus,
