300 Mr. G. E. Bodkin's Notes on 



colour with a peculiar though not unpleasant odour. 

 These masses of foodstuff weigh about 2'5 grammes, and 

 an equal quantity is deposited in each cell. On this mass 

 the egg is finally deposited and gradually increases in size 

 as development jjroceeds ; later, the segmentation of the 

 future larva may dimly be perceived through the envelop- 

 ing shell. It is sausage-shaped, slightly curved, and almost 

 transparent in the earlier stages. Length 1 "7 cm., diameter 

 0"4 cm. During development one end becomes somewhat 

 larger than the other. Eventually the extremely thin 

 pellicule strips off and the wrinkled larva is exposed, 

 which starts feeding immediately. The larval excrement 

 is hard, and formed in short rods black in colour. The 

 full-grown larva measures 3' 9 cm. in length, and is creamy 

 white in colour. The larval stage lasts about three weeks. 

 Gradually the outlines of the pupa may be seen through 

 the larval skin, which eventually peels off. The ])eriod 

 between the full-fed larva and the final stripping of the 

 larval skin is -18 hours. The pupa is at first creamy white, 

 and in form roughly resembles the future adult insect. 

 Length of pupa "J "5 cm., breadth Vi cm. AVithin the first 

 week of pupation a general darkening of colour takes 

 place, the eyes going almost black; hardening of the 

 integument occurs simultaneously. These two processes 

 progress rapidly till the perfect insect is formed in about 

 3 weeks. It then makes its exit from the cell by gnawing 

 away the wad of hardened sawdust.
