INSECTS IN THEIR RELATION TO FLOWERS. 147 
Meracium, Verbascum nigrum, and Hypericum perforatum, then 
visited S. jacobea 16 times, Hieracium once, S. jacobea 10 times 
(on a plant already visited), revisited for a moment plants of 
Hypericum perforatum, then actually returned to plants of S. 
jacobea previously visited, again sucking the flowers thoroughly, 
afterwards going to Hieracium 1, S. jacobea 9 (on a fresh plant), 
touched Trifolium pratensis and a flower of Hieraciwm, thoroughly 
visited the flowers on a fresh plant of S. jacobea, then went back 
to several of the old plants of S. jacobea already (to all appear- 
ances) well visited several times, and revisited them thoroughly, 
afterwards visiting five flowers of Malva sylvestris, and finally flying 
off. As all this took place within an area of 10 or 20 yards 
square, this bee evidently did not believe in being very methodic, 
or in taking very long excursions. Most of the flowers on the 
bank were yellow, suchas Senecio jacobea, Hieracium, Hypericum, 
and Verbascum. ‘The bee paid about 200 visits to 5 species, 3 of 
which were yellow and 2 red. I counted 91 visits to Senecio, but 
the real number must have been at the very least twice that, while 
the visits to Hieractum were 3, to Hypericum 1, to Trifolium 1, 
and to Malva 5. ‘The visits to the three last-named species were 
very short, so that perhaps the error was perceived before the 
nectar was sucked. 
11.—Sept. 25,1881. <A garden with a great variety of flowers 
at Great Saling, Kssex. A large humble-bee visited one flower 
of the Agapanthus lily, several flowers on five plants of red 
Antirrhinum majus, one a pink Hydrangea, touched white Antir- 
rhinum but passed the red unnoticed. Several minutes later the 
same bee (I think) visited many flowers on another plant 
of Agapanthus, thrice taking flights and returning, then, after a 
long rest on the greenhouse, visited two flowers of Delphinium 
and was lost. ‘This observation shows very little method, if any. 
12.—Same date and place. A smaller bee visited several 
flowers of scarlet geranium (perhaps only settled on them), two 
of Nasturtium, several on Linaria cymbalaria and was then lost. 
13.—Same date and place. A smail humble-bee, first seen on 
Delphinium, visited several flowers both of Fuchsia and of scarlet 
Lithospernumm, returned to Fuchsia after having touched Geranium 
and was lost. 
14.—Sept. 26, 1881. Bridge-End Gardens, Saffron Walden.
