THE BEE. 103 



compound J wings, legs, and all the other portions 

 of its external organization. 



In the metamorphosis from larva to pupa, a con- 

 striction takes place between the first and second, 

 and another between the fourth and fifth rings of 

 the body ; the first becoming transformed into the 

 head, with its antennae, oral apparatus, &c. ; and the 

 second, third, and fourth into the thorax, with its 

 accompanying members ; whilst the remaining rings 

 constitute the abdomen. The large compound eyes 

 at first resemble two small dark streaks, one on each 

 side of the head, and even at this early stage their 

 composite structure is discernible under the micro- 

 scope ; the various members of locomotion do not 

 grow out of the body, but appear upon the surface, 

 moulded, as it were, under the manipulations of the 

 invisible hand of Nature. 



At first they remain adherent to the body through- 

 out their whole length; but as the metamorphosis 

 proceeds they become detached, and at length the 

 yellowish pupa (for it retains the characteristic colour 

 of the larva for some time after the change has be- 

 gun) assumes a dark- brown hue, the external skin 

 becoming hardened, and it then presents the appear- 

 ance depicted in the illustration (PL VIII. fig. 8). 

 Simultaneously with these external changes in the 

 Bee's structure, a transformation is taking place in 

 its internal anatomy. This in the larva is of the 

 simplest kind, being adapted to the habits of the 

 insect, and ministering to its rapid growth.
