but which can easily be told by having a deep reddish-brown spot on 
each side of the first thoracic segment ; the legs are also longer than 
in the Cockchafer grub, and the whole surface is clothed with 
transverse rows ol reddish-brown hairs. The larvae may also be 
found amongst rotten and rotting wood, but mainly in rich soil ; their 
food consists chiefly of the roots of various plants and probably of 
decaying vegetable matter as well. When full grown they attain the 
length of an inch and a half, taking from two to three years to reach 
maturity. The pupal stage takes place in an earthen cell over an 
inch in length formed deep in the ground ; the outer part of the cell is 
rough, the inner surface smooth. The pupa is of an ochre colour.

The grubs apparently pupate in the summer, and the beetles appear 
from these in the following May and June. Canon Fowler notes that 
the little larvie and perfect insects are often found in ants’ nests. 
Remedies. 
By far the most successful way to cope with these large sluggish 
beetles is by “ hand-picking.” This should be done during dull 
weather when they are very cpiiet, as on warm days they become 
more active and fly about. 
Heaps of leaf mould, cucumber beds, and heaps of decaying wood 
should be examined when turned over or moved and the grubs hand- 
picked. Old tree stumps frecpiently harbour them and should thus 
be grubbed up in the winter and burnt. In garden and field 
cultivation poultry do much good if turned on to the land when it is 
being broken up, for they greedily devour these larvre as well as those 
of the Cockchafer. 
“ Turf-traps,” i.e. heaps of rotting turf, may be left here and
