. Handbook of flower pollination : based upon Hermann Mu?ller's work 'The fertilisation of flowers by insects' . Fertilization of plants. LEGUMINOSAE 297 is visited, cross-pollination is consequently effected. As anthesis progresses, the brownish tint which replaces the original golden-yellow colour becomes more pro- nounced. At the same time, the vexillum with its 12-16 wavy ribs, becomes applied to the other parts of the flower, and closes the entrance to them. Visitors.—I observed the honey-bee, and Bombus pratorum L. 5 at Kiel; in Sylt only the former. 702. T. procumbens L. (main variety).

Alfken noticed the following bees at Bremen.— I. Andrena parvula JST. 5; 2. Nomada succincta Pz. MacLeod observed 3 Lepidoptera in the Pyrenees ('Pyreneenbl.,' p. 437).. Fig. 96.
