645' 



Out of the 42 larvae which hatched on 16th August 1911, eleven were 

 living on 19th December 1911, Their measurements in m.m. were as. 

 follows : — 



The measurements of the other parts of the first of the above which 

 looked the largest of all were : — 



24 m.m. from eye to eye (outside margins). 

 2 m.m. across the posterior part of the head. 

 4 m.m., length of the filiform part of the antenna. 

 I m.m., length of the antenna. 

 The colour was that of dry dust with a greenish and in places a yellowish 

 tinge and scattered black specks in the sabmedian regions on the back. 

 On the 10th July, the same larva measured : — - 



16 m.m. from the head to the tip of the abdomen. 

 8 m.m. across the middle of abdomen. 

 4i m.m. from eye to eye (outside margins). 

 4 m.m. across the posterior part of the head. 

 The jaws were 4 m.m. long, measured in the curved state. The anten- 

 nee were of the same length as on 19th December 1911. 



There was no change in shape or colour. There were four other larvee^ 

 living on this date, and they were all grown to about the same size. They 

 were full-grown and began to pupate on the 16th July. 



Moulting. — The larva seems to undergo only three moults, the third 

 revealing the pupa. 



One lot of larvse which hatched on SOth October 1908 passed through 

 the first moult from 20th to SOth March 1909 ; began the second moult on 

 20th May 1909, but all died by 22nd June 1909. 



A second lot of larvse hatched on 7th November 1 908, passed through 

 the first moult from 25th March to 15th April 1909, began the second 

 moult, 31st May 1909, and all died by 8th July 1909. 



A third lot hatched on 8th July 1912, went through the first moult on 1st 

 September 1912. Only one survived and moulted for the second time on 

 6th April 1913. On the 29th April, this larva was about 13 m.m. long and 

 was full-grown. 



In moulting, the skin first bursts along the mid- dorsal line, the fissure 

 extending from the junction of the prothorax with the head to the third 

 or fourth abdominal segment. The crack then divides, extending horizont- 

 ally along the posterior margin of the head on both sides and then turning
