MEDITERRANEAN FLOUR OR MILL MOTH. 95 
All measures, whether of treatment of the ground or of liberal 
and rich manuring, of a nature suited to drive on hearty growth are 
of use in supporting infestel plants if of material suited to its special 
nature, but nitrate of soda (so far as reports to myself go) has proved 
nearly or wholly valueless as an antidote to Helworm-sickness.

The infestations above named have all been entered on before in 
due course, but as some additional points of serviceable information 
have accumulated I give the observations under the collective heading 
of ‘* Stored Grain and Flour,” with a repetition of just sufficient of 
the life-histories of the insects to make the notes intelligible without 
referring back. 
In regard to the destructive flour pest known with us as the 
‘‘ Mediterranean Mill Moth,” the researches of various enquirers, both 
European and American, during the last few years have shown that the 
existence of this infestation has been known of in different countries 
for a much longer period than at the first observation of it as an 
important pest—in the year 1877—was supposed to be the case. Also 
the distribution of its presence in various countries has proved to be 
more general; and also, and more recently, it has been recorded from 
European and American observations that, under pressure of circum- 
stances, the larve or caterpillars of this Mphestia kithniella moth by no 
means restrict themselves to consumption of Wheat flour, which is 
their special food, but will extend it to unbroken grain, and to flour in 
manufactured and baked condition.
