grubs of various kinds of Chafers are now proving in 
the Southern Island of New Zealand. 
The Daddy Longlegs grubs come out at niglit to feed, 
or travel on the surface, and are then open to rolling or 
other measures of destruction; some of our turnip and 
cabbage caterpillars are similarly open to attack at 
night, or in the dusk hours, andjthe great caterpillars 
of the Death’s Head Moth, which sometimes do great 
harm to the leafage of the potato, are variable in their 
time of feeding, so that it is desirable for some one 
interested in the matter to ascertain the habits of the 
special caterpillars before setting destructive operations 
on foot. 
The Click Beetle, the parent of the Wireworm, may 
be swept up in great numbers in the evening from 
grass ; and, on the other hand, the Turnip Flea-beetle 
rejoices in the sunshine, and then flies far and spreads 
rapidly. 
It is points such as these that we need to know more 
of ; it is the province of the entomologist to give the name 
of the insect, and to know the precise history of its 
method, and place of existence; but it is the province of 
the agriculturist to notice, in real practical and con¬ 
tinuous observation, the various influences which act 
upon it, and, may I not add, when observed to make 
them known. It is a matter of great importance—it is 
nothing less than the daily bread of the nation, which, 
for want of attention, is being in many cases absolutely 
thrown to the insect-vermin, whilst the landholder is 
distressed for want of the crops which need not have 
been lost. 
There is an enormous amount of solid practical in¬ 
formation in the hands, or rather in the minds, of many 
agriculturists on many points bearing on insect-preven¬ 
tion, and if they could but be persuaded to believe how 
solidly valuable it is, and to impart it for publication 
without regard to whether they know the scientific name 
of the insect (which is of no consequence, as they can 
always be furnished with it), it is beyond believing how
