1922. On the same day some of the larvae were put on moist soil in 
individual vials and others were placed on moist soil in salve boxes. 
< 
On June 10 the larvae in the salve boxes were removed to moist soil in 
petri dishes. Later these larvae were also transferred to moist soil in indi¬ 
vidual vials. The vials were kept in salve boxes in an out-door cage and 
were all later numbered. An attempt was made to keep the soil in a uni¬ 
form moist condition and observations were made on the specimens 
throughout the summer. Pupation was found to begin in very late 
August or early September and continued throughout September and 
early October. One specimen was observed to be in the process of pupa¬ 
tion as late as November 27, 1922.
