aftel* the hatching, a tact which deserves attention as the liead 

 and ^ the tuberoles are hhiek from tlie beginning. 



MesotJiorax and 3Jefathurajr. S. dorsalis^ s. siqjrastif/iitalis^ s. dor- 

 solateralis^ a small s. prostigmalis, no rudimentary stigma, though 

 the tracheae are seen through the skin ; s. hasalis, sometimes a 

 s. pedalis. 



On the border of the mesothorax and metathorax is a rudi- 

 mentary stigma. 



Abdomen 1, 2. S. dorsalis^ s. suhdorsalis^ s. suprastigmalis^ s. 

 pof^tstignmlis^ s. infrastigmalis^ three s. hasales. 



Even after repeated examination I could not fiiid in my ma^ 

 terial a s, prostigmalis. 

 Segrii. 3^ — 6 = 1, biit two s. hasaJfis on one tuberculum. 



^ 7 = 1, two s. hasales. 



,, 8 = 1, two s. hasales, large stigma. 



„ 9 = 1, no s. infrastigmalis, in the beginning a rudimen- 

 tary stigma (?). 



,, 10. S. dorsalis, s. subdorsalis and s. suprastigmalis with 

 that of the other side on one median anal shield which 

 gets black from half an hour to two hours after the hat- 

 ching, whilst the tubercles are immediately black, two 

 s. hasales, rather far from each other. 



„ 11. Behind the anal shield is a black spot with a single 

 seta. I think that a part of the s. hasales of 10 belongs 

 to 11, as s. infrastigmalis fails already on 9. 



Towards the time of moulting brown-red spots appear between 

 the primary setae, which are mostly ring-shaped. They also arise 

 as a broad border round the primary tubercles, and are due to 

 the transparency of the skin which allows the colours of instar ƒ / 

 to be visible. 



Instar il. Lengtli 4 mm.. Duration 4 days. ïhe skin bursts just 

 behind the head. The caterpillar creeps out at tlie front, as wlien 

 leaving a bag, the skin of the head remains for a short time as 

 a shield on the head. The caterpillar does not eat the old skin. 



In the middle of the back we see a ratlier sharply confined.
