flattened against the under surface of the elytra (e). Each wing projects 

 in part beyond the outer margin of the elytron, under which it lies. The 

 metathoracic segment also bears the third pair of legs (z) which lie between 

 the body and the elytra. 



The mesothoracic segment and the first five abdominal segments carry 

 each a pair of spiracles (*). The spiracles are oval in shape. The thoracic 

 spiracle, as in the larva, is far the largest one. 



Fig. 12. Pupa of S. carcharias, dorsal view (greatly magnified). a t = head ; b t = first thoracic 

 segment; c x = second thoracic segment; d x = third thoracic segment; e 1 = abdomen; 

 .sc = scutellum; sg = scutellar groove; other letters as in Fig. 11. 



In the dorsal view of the pupa (Fig. 12) it is seen that all the segments 

 of the thorax and abdomen bear bristles, the prothoracic (pr) bristles 

 being more marked than those of the other segments. 



In the centre of the mesothoracic segment (ms) lies the scutellum 

 (sc), while the metathoracic (mt) shows a fairly wide longitudinal groove, 

 the scutellar groove (sg).
