PROCRIS GBRYON. 93 



larva is about 12 mm. long, soft, and fat looking, 

 nearly cylindrical, and somewhat fusiform, being 

 stoutest at segments 9 and 10 ; the head very small, 

 and retractile into the second segment, which is smaller 

 than any other segment ; the segmental divisions well 

 denned. On segments 3 — 12 are eight rows of large 

 raised tubercles, those on the back being transversely 

 elongated ; all are set with fine short bristles ; the 

 skin between is set with tiny hard dots, which when 

 somewhat magnified are seen to be like stars with five 

 or six points. These dots do not extend below the 

 spiracles. In colour the head is glossy black; the 

 second segment has a blackish plate with yellowish 

 edge in front ; the back and the tubercles on it are 

 either dingy white or pale yellow, with a double dorsal 

 line of purplish-brown enclosing a whitish thread. 

 The back is bordered with a waved line of claret, 

 below which comes a wide reddish-brown stripe bear- 

 ing the row of large lateral tubercles of the same 

 colour, but narrowly outlined with pale flesh colour. 

 This reddish-brown stripe extends to just below the 

 spiracles, which are of the same colour and round in 

 outline, and finely ringed with black; next comes a 

 stripe of pale flesh colour bearing a row of tubercles of 

 the same colour, but outlined with brown, then a 

 stripe of brown, then the lowest row of tubercles of 

 paler brown ; the belly dingy flesh colour, the thoracic 

 feet with blackish rings, the ventral feet yellowish; 

 the bristles are dirty whitish with blackish tips. 



The larva spins low down among the stems of its 

 food plant a little tough webby cocoon, but not stout 

 or papery in texture, of somewhat fusiform shape, 

 about 12 mm. long, and 5 mm. at its widest, in colour 

 dirty greyish with a slight yellowish tinge ; the pupa 

 is about 9 mm. long, fusiform, the head small, the 

 abdomen plump ; the eyes and antenna-cases well 

 developed, the wing-cases long and free at the edge, 

 the tongue-case reaching nearly to the tail and free 

 beyond the edge of the wing-cases, with one pair of
