In this work, the subject is brought down to the present time, from the 
German edition of 1873. It is divided into four parts — Historical Intro- 
duction ; The Insects which visit Flowers ; The Mechanisms of Flowers ; 
General Retrospect. A full bibliography and indices cf Insects and 
plants are added. Many of the woodcuts illustrate the adaptive organs 
of Insects, as well as of plants.

regards the chorda of Arthropoda and Vertebrata as both morphologically 
and physiologically homologous.

In Zaraia fasciata , the colour of the cocoou depends on the food, larvae 
fed on strawberry forming dark brown resinous cocoons, aud those fed on 
honeysuckle forming pale greenish cocoons. Larvae and perfect insects of 
the same sex differ considerably in size. The position of the embryo in the 
egg is irregular both in Z. fasciata and Gastrophysa raphani. In Rumia 
cratccgata , the eye-spots invariably occupy the same position in the
