Of the larvae and pupae obtained, some were killed and preserved 

 immediately, while an attempt was made to rear the adult insects from 

 the others, on account of the difficulty of identifying larvae. In some 

 cases this was successfully accomplished, but in a number of cases it 

 did not succeed. 



In addition to the examination of the insects actually present in the 

 soil, large numbers of adult insects were obtained by sweeping the herbage 

 with a net, a large proportion of which were insects with soil inhabiting 

 larvae, but in addition to these, other species were taken whose presence 

 was due to accident or to their having migrated from their breeding 

 place.
