They do notusually descend very deeply into the ground, but remain where juicy roots are mostabundant, and the only marked alteration to which they aresubject during the long period of their existence under groundis a gradual increase in size. As the time for their transformation approaches, they as-cend towards the surface, making cylindrical burrows aboutfive-eighths of an inch in diameter, often circuitous, seldom. 38 INSECTS INJURIOUS TO THE APPLE.

As the insect progresses,the chamber is filled below by the earthy matter removed inits progress, but the upper portion, to the extent of six or eiglit inches, is empty,and serves as a dwell-ing-place for the insectuntil the period for itsexit arrives. Here itremains for some days,ascending to the top ofthe hole in fine weatherfor warmth and air, andoccasionally looking outas if to reconnoitre, butdescending again on theoccurrence of cold orwet weather. In locali-ties that are low or im-perfectly drained, the insects sometimes continue their galleriesfrom four to six inches above ground, as shown in Fig. 26,leaving a place of egress at the surface, e, and in the upperend of these dry chambers the pupse patiently await the timefor their next change. This period, although an active one, is the pupal stage ofthe
