land. Unfortunately, as the series of larvae is so incomplete, one can only guess at the 

 age as expressed in the number of the stage, and I am by no means satisfied that the 

 assumption that this larva is in stage VIII is correct. At all events it cannot be older. 

 We know too little about the duration of stages to estimate age in days, but a guess of 

 six weeks may be fairly near the truth. In any case there is evidence here of rapid and 

 extensive travel.
