 Ford (Ann. Appl. Biol., S (1017), No 2-3, pp. 97-115, pis. 2, fig. i).— This is a 

 report of studies of the immature stages of the comm >n wireworm in Cheshire, 

 North Staffordshire, and South Lancashire.

 pupal period is about three weeks ; the imago remains resting motionless in the 

 pupal cell for roughly two months, after which it comes to the surface, and 

 hibernates under stones, clods, etc., until the next season."
