Report of the Entomologist. 21 



has been traced during the entire year from its emerging from the 

 egg in early spring to the deposition of the eggs by the oviparous 

 females in the fall. Experiments were carried on against the 

 eggs during the winter also. 



A series of experiments to test the effect of kerosene emulsion 

 on white grubs on a lawn were carried on, but with only negative 

 results. 



Considerable work has been done on several species of cut- 

 worms, notably two species of climbing cut-worms which did 

 much damage to young peach trees, and one species which practi- 

 cally destroyed the second growth of clover over an area of eight 

 or ten acres. 



Tenebrioides mauritanica injuring stored wheat is under inves- 

 tigation, and its egg stage, which seems not to have been before 

 observed, has been studied. 



These details will serve to show the nature of the work in prog 

 ress, although the species enumerated are merely the more 

 important ones of those studied. 



Very respectfully yours.
