Notes on the early stages and habits of Pieris manni, Mayer 



[ivitlt plate). 



By H. POWELL, F.E.S. 



(Concluded from p. 40). 



Larva. — Fufit instar : Just after hatching the larva of /'. manni 

 measures about l-8mm. in length. At the end of the instar barely 4mni. 

 The head is black and shiny, rounded, slightly flattened in front ; lobe 

 division well marked. The head setje colourless, bent forward and 

 downwards. The body is thin in proportion to the length. Skin 

 shiny, thin and delicate-looking, semitransparent, pale-yellowish, and 

 studded with minute black spots on dorsal and lateral areas. After 

 feeding has conniienced a greenish-grey tint appears, the green con- 

 tents of the alimentary canal being visible. The ventral surface 

 remains yellowish. Segments and subsegments well marked. Each 

 tubercle bears a colourless hair, apparently terminating in a small 

 knob. The exact form of this swelling is rather difficult to distinguish 

 with the aid of a hand lens alone. Towards the end of the stage a 

 faint yellowish dorsal line is visible, merely an indication of the yellow 

 line which develops later. 



Second instar. — Length at the end of this instar 5'75mm. Body 

 rather less slender in proportion to length. Head rounded, lobe 

 division well marked, shiny, black on top and on the sides, yellowish - 

 green around the mouth-parts, greenish with a black suffusion around 

 the ocelli and on the facial triangle. The head hairs seem to be more 

 numerous than in the preceding stage. Colour of body more decidedly 

 green than before, but the feet, the ventral surface, and the last few 

 segments remain yellowish. Dorsal line more strongly marked, but 

 still faint. The numerous brownish-black points on the dorsal and 

 lateral surfaces give a slightly grey appearance to the larva when seen 

 with the naked e3'e. The anterior edge of the prothorax is furnished 

 with a fringe of stiff brownish hairs, bent forwards. The hairs arising 

 from the tubercles on the bodj' are rather stiff-looking, short, but of 

 unequal length, and more numerous than in the first stage. 



T/iird instar. — Length at the end of this stage 9"6mm. Head, 

 immediately after the moult, of an uniform pale green. On drying the 

 black suffusion reappears, but is less extensive than before. The head 

 continues shiny. The tops of the lobes are black still, but less intense 

 black ; in some specimens it is more of a dark grey. Around the 

 ocelli the colour is greenish, the facial triangle is greenish with a
