them, especially the oak, but in this stage they do not attack 
strawberry, all the damage to that plant being done by the

>oon after pairing, the female creeps into the earth, especially 
erever the soil is loose and rough, and dies after depositing forty 
fifty eggs. These, hatch in the course of a month, and the grubs, 
wing slowly, do not commonly attain full size until the early 
ing of the third year, when they construct an ovoid chamber 
i'd with a gelatinous fluid, change into pupae, and soon after into 
ties. Occasionally, however, individuals complete their trans- 
tnation in the ground in autumn, and hibernate in the adult con- 
on, without leaving their pupal cells until the following spring. 
-he injuries done to the strawberry by this grub are similar to 
se inflicted upon other plants, as they devour both the princi- 
and fibrous roots. These injuries are most apparent, of course, 
strawberry fields which have been newly set upon ground pre- 
usly infested by the grub, especially upon old grass lands; but 
re is some evidence that the beetles lay their eggs freely in the 
iwberry fields themselves. 
1 his is one of the most unsatisfactory species with which the 
i iwberry grower has to deal, and no efficient remedy has as yet 
n discovered for its ravages. The fact that the beetles are strongly 
racted by light at night, during their most active season, may be 
d to lure them to destruction, by so arranging reflecting lamps 
lanterns that the beetles flying against them shall drop into tubs 
water upon which enough kerosene has been poured to form a
