This beetle, the lars-a of which is the too well known white grub, 

 is much less harmful to the elm than to those plants which it at-

 beetles are as abundant as they are sometimes, they destroy no

 as they fly about them at night in May or June. This beetle 

 LacJDiostema fnsca^ Frohl. was described, and remedies sug- 

 gested in the Second Report of the Vermont Experiment Station, 

 but as no figures are given in that paper, they are given here from 

 a cut obtained for the Third Report. The figures are natural size 

 and give a very good idea of the insect. It is important that as 

 many of the beetles be destroyed as possible, for this will tend to
