Paper No. 229, 1888, says: ‘‘ This acquisition renders the collection 
at the Museum of ancient cave remains the most complete that is 
known to archzeologists.”’ 
I visited the Kensington Museum and the Museum of Natural His- 
tory, now presided over by Prof. W. H. Flower. Prof. Flower was 
president of the British Association at Newcastle this year, and his 
address was devoted to the organization of museums so as to produce 
the greatest benefit for students and for the public.—Zhomas Wilson. 
ENTOMOLOGY. 
The Flour Moth.—A new insect pest has recently made its 
appearance on the continent of America. It is known as the flour 
moth (Zfhestia kuhniella), and its ravages, as its name indicates, are 
seen in the destruction of flour, in which it weaves its webs, and upon 
which the caterpillar feeds. As it is very destructive, and increases 
with marvelous fecundity, it is of the utmost importance that every 
precaution should be taken to prevent its spread. 
The flour moth is indigenous to the Mediterranean, and a few years 
ago it would have been likely to stay there. But increasing commerce 
has its attendant dangers. Experience has shown that as trade in the 
milling industry enlarges, weed and insect pests, confined at one time 
to a certain locality, have spread to places far distant. The flour 
moth has probably come to America with importations of seed wheat, 
or in bags in which flour has been exported, and which before their 
return may have been stored for a time in some place infested by the 
insect. 
The color of the fore-wings of this moth may be generally described 
as of rather pale gray, with darker transverse markings. The hind 
wings are peculiar for their whitish semi-transparency, with a darker 
line from the point along a part of the fore edge. The accompaning 
illustration will convey a general idea of the appearance of the moth. 
An examination of the flour infested by the insect shows a mass 
completely spun together with the web. Giving the result of his 
_ investigations, an expert tells us he found it so inatted together that, 
a fter pulling some lumps of it away, he found that the rest hung down
