 90 wide. 



Newly hatched larva. — Pale crimson (after boiling in 

 KHO), greatly elongated (about 285 ^ long and 90 wide), 

 without rows of spines, but with longitudinal rows of figure- 

 of-8 glands ; legs and antennae well developed ; caudal 

 tubercles not elongated ; anal tube present, but broad and 

 shallow, with the anal lobes projecting; tibia very short; 

 anterior legs with tibia about 8, tarsus 21 /a; a very long-
