In Table XL the totals from the foregoing tables on length of time 
spent in the soil are given for more ready comparison. The hori- 
zontal bars divide the period into weeks, beginning with the third 
week. The percentages of total adults emerging each week are also 
shown. Except in the Ohio records, which are perhaps abnormal, 
and the Georgia record for 1906, comparatively few beetles were out 
within three weeks from the time of entering the soil by the larve. 
During the fourth and fifth weeks, however, the great majority of 
beetles appear and by the close of the sixth week emergence has 
practically ceased.
