places, especially in California, and quotations from a large num¬ 
ber of correspondents on this subject. In the May number (68) I 
announced the discovery of the pest in New York State, which is the 
first record of its occurrence in destructive numbers in mills in 
the United States east of the Eocky Mountains. In the October 
number (72) I gave a brief account of the methods now used in Cali¬ 
fornia and New York for keeping the flour m >th in check, together 
with other notes and observations. In the November issue (73) I 
announced the discovery of a new parasite (Bracon hebetor Say) 
of this insect, and added a new locality. The facts which led to 
the discovery of the parasite are discussed somewhat in detail, 
suggestions are made for its colonization, and extensive notes re¬ 
garding the new Canadian outbreak are given. 
Mr. F. H. Chittenden, Assistant Entomologist to the United 
States Department of Agriculture, in an article entitled “The 
more Important Iasects Injurious to Stored Grain,” gives a short, 
somewhat popular account (71) of the Mediterranean flour moth. 
The article is illustrated, and contains the most perfect represen¬ 
tation of the adult moth ever published. It is reproduced by per¬ 
mission on p. 9 of this paper. Mr. Chittenden also contributed 
some valuable notes previously unpublished. 
In December, 1895 (74) I called attention to the fact that I had 
discovered Bracon liebetor Say feeding upon the larvse of the 
Mediterranean flour moth, and further stated that I had bred a 
single specimen, a male, from the same lot of larvse, which differed 
in many respects from typical specimens of hebetor , but was 
thought by Mr. Ashmead to be a small variety of the same 
species. B. gelechice , although not found on the flour moth, is 
mentioned, as it is closely related to B. hebetor ; and reference is 
also make to the European parasites of this insect, B. brevicornis 
and Chrymelus rubiginosus. 
I note next a communication from a Pennsylvania miller, Mr. 
E. Burns, who states (75) that he has been troubled with the 
flour moth in his mill for the last three years. He has been 
fighting it, principally, by keeping an extra sweeper, which adHs 
about $500 per year to the running expenses of the mill. He 
says he tried sweeping his mill with steam some years ago, and 
found it worked well in the summer, when all the doors and win¬ 
dows were open, but as soon as cold weather set in he could not 
use this method, as the “steam on the cloths of the purifiers 
makes all good middlings run over the tail end of the machine.” 
This information adds a new locality for the flour moth, as it has 
not heretofore been recorded from Pennsylvania. 
Comments upon this outbreak and a few notes concerning the 
flour moth, with illustrations, were published (76) by me in 
January, 1896; and in February I replied (78) to a query from 
a milling firm in Melbourne, Australia, who had forwarded me 
for examination a sample of flour matted together in a way to sug¬ 
gest the work of the flour moth. No insects were found in it. 
An illustration accompanying my reply shows a sample of wheat 
flour felted together by the flour moth.
