INSECTS IN THEIR RELATION TO FLOWERS. 181 
67.—Same date and place. Near the scene of the foregoing 
observation a moth, about twice the size of Plusia gamma, visited 
Silene nutans twice, Centawrea scabiosa once, and was lost. 
68.—Aug. 14,1882. Rocky slope, near St. Moritz. A smallish 
striped humble-bee paid forty-three consecutive visits to Hpilo- 
bium angustifolium, and one to Phytewma orbiculare, after which I 
lost him. Other flowers were not numerous around, but there 
were a few, such as Sempervivum montanum, Solidago virgaurea, 
Campanula, and a large umbelliferous plant. 
69.—Same date and place. A bee of the same species paid 
twenty visits to Hpilobium angustifolum, avoiding all else. 
70.—Aug. 16, 1882. Steep rocky river-bank, near Falls of 
St. Moritz. A humble-bee was seen to visit Hpilobium angusti- 
folium thirty-four times, Rubus ideus once, and was lost. 
71.—Aug. 19, 1882. Same place as obs. No. 68. A specimen 
of the Apollo butterfly paid four successive visits to Carduwus 
pratensis, avoiding Campanula, Solidago virgaurea, Scabiosa 
succisa, Dianthus deltoides, Achillea millefolium, &e. 
72.—Same date and place. A copper-coloured butterfly visited 
Solidago virgaurea three times, and was lost, after having hesitated 
at, but rejected, a plant of the same, a Hieraciwm and a Potentilla 
(twice), all these being yellow. Other flowers on the same spot 
were Campanula and Silene ? 
73.—Aug. 22, 1882. Meadow at St. Moritz. An individual 
of Argynnis lathonia visited consecutively twenty-seven flowers of 
Viola lutea, taking, however, several considerable flights between 
some of the visits. Other flowers on the same patch were Lychnis 
diurna, a small Veronica, and a hop trefoil. 
74.—Aug. 23, 1882. Mountain side over Roseg glacier. A 
medium-sized black humble-bee, yellowish behind, visited T'rifo- 
lium repens twelve times, avoiding all else, though plenty of 
Parnassia palustris grew around, with some Achillea millefolium, 
Hieracium, Aconitum napellus, &e. 
75.—Oct. 1, 1882. Garden at Chignal. A specimen of Pieris 
brassice visited one flower of scarlet Geranium, three of pink 
Geranium, took a flight, settled, returned, visited pink Geranium 
once, hesitated over Petunia, and lastly visited six more flowers 
of pink Geranium, having passed over plenty of scarlet Geranium, 
red Papaver, red and white Antirrhinum, asters, &c.
