 • back which characterise the latter, and they differ also in having 

 on each side of the front of the head a very minute but quite 

 distinct black spot, where in the older larvae, the •small convex, 

 simple eye, scarcely different in colour from the surrounding 

 integument, makes its appearance. 



As they gradually grow and increase in size, the burrows they

The larvae are almost entirely white in colour, the head
