Although this caterpillar (Fig. 292, h, r-, and il.) is provided 

 with a full complement of sixteen legs, yet in walking it is 

 obliged to arch U}) its body, somewhat as the span-worms do. 

 This is due to the fact that the front pair of legs l>eneath the 

 middle of the body are so much shortened as to be of no use 

 to the caterpillar, \\lien about to pupate it rolls a leaf around 

 its body (Fig. 292('), fastening the edges together with silken 

 threads; it then lines the interior with a layer of silk, and 

 soon afterward assumes the })Upa form. (Fig. 292/.)
