 The primitively upper surface of the middle thoracic ring 



(Fig. 18). 

 Transformation, changes of food into tissue and of tissue into 



waste products. 

 The primitively upper surface of the third or posterior 



thoracic ring (Fig. 18). 

 The third thoracic ring or segment (Fig. 18). 

 Small bristles, as opposed to macrochaetae, in Diptera. 

 Beaded like a necklace (Fig. 183). 

 A term which was applied to the cornicles of the Aphids 



under the mistaken notion that these structures secreted 



the honey dew (Fig. 88).

(Fig. 88). 

 Wrapped in a hard covering (Fig. 39).

 Reproduction in the larval or the pupal stage. 

 Reproduction by direct growth of germs from egg-cells

 Plural of pleuron or pleurum; the lateral sclerites between 



the dorsal and sternal portion of the thorax; in general, 



the sides of the body between the dorsum and sternum. 

 Production of more than one embryo from one egg. 

 Soft, pad-like structures between tarsal claws; the cushions 



of short stiff hair or other clothing on the under side of 



tarsal joints; rarely fleshy lobes (p. 14). 

 The intermediate stage between larva and adult (Fig. 39). 

 The thickened larval skin within which the pupa is sometimes

(Fig. 127). 

 Like net-work.
