vation until their .numbers increase so much as to render their presence 
alarmingly patent. 
Remedy. — Cleanliness where such is practical is essential to keep free of 
these insects. In mills and warehouses where flour dust and grain is every- 
where, the Carbon Bisulfide fumigation must be resorted to, and must be 
very thoroughly done, so that the vapor of the substance will find its way 
into the cracks and crevices where these pests hide. In addition, pyrethrum 
powder should be blown into the cracks where they are known to hide, or 
pure kerosene oil may be blown in with an ordinary oiling can. Powdered 
borax sprinkled on shelves where they run will drive them away. Old rags 
moistened with molasses water in which Paris green has been suspended will 
poison them. The cloths should be freshly moistened each evening and 
removed in the morning. 
The Grain and Rice Weevil (Ca/andra)— Two Species. — In the South- 
ern States we have two species of grain weevil, Ca/andra granarius , which 
infests wheat and corn, and Ca/andra oryzee , which infests rice in warehouses, 
fhe first is the more common and injurious. Both species are much alike. 
Fig 3 shows a back and side view of a weevil of this family, but this is 
much larger than the true grain or rice weevil. The grain weevil is dark- 
brown, or nearly black, is very slender and about one-eiglit of an inch long. 
Immense quantities of wheat corn and rice are an- 
nually destroyed by these pests in warehouses, stores 
and homes. The only practicable remedy for these 
pests is Carbon Bisulfide The infected grain 
should be put in an air tight box or biu and a dish of 
the liquid laid on top of the heap. The whole must 
then be tightly covered and left for twenty-four to 
forty-eight hours. Then expose to the air until all 
odor is gone. The grain or flour will not be injured 
by the carbon. Use at the rate of one and a half to two pounds for each ton 
of grain, and cover tightly so as to keep in the fumes until the insects are 
killed. They are exceedingly tenacious of life. 
The Flat Flour BsKThE-Si/vanus Stir inaininsis. -This is a narrow brown 
beetle one-twelfth inch long, and scarcely thicker than a sheet of paper. It is 
a native of Asia, as its name betokens. It is becoming yearly a greater pest 
in the Southern States, and will probably exceed in mischief even the Calandra 
weevils. The remedy- for this is. the same as for the odiers — Carbon Bisul- 
fide. This insect is fond of greasy substances, and if some paper is soaked 
in melted lard and Paris green sprinkled upon it while moist, and the poisoned 
sheets distributed on floors and shelves wh re grain and flour is kept, many 
of the beetles will be killed; but this plan will not give satisfaction where they 
are already abundant, being too slow in its operation. The carbon will kill 
most of them in a very short time when it is properly used. 
As a matter of safety all mills, warehouses and stores where grain, flour 
and food stuffs are kept, should receive a thorough annual cleaning, and fum- 
igation with Carbon Bisulfide. This, if attended to and thoroughly done, 
will save many thousands of dollars’ damage. It will be most efficacious vf 
done about April i. It may be repeated with benefit in July or August.
