places, especially in California, and quotations from a largp num- 

 ber of correspondents on this suhjVct. In thn Mav number (68) I 

 announced the discovery of the pest in New York State, which it. the 

 first record of i s occurri-nce in d^struc ive uunbHrs in mills in 

 the United States east of the R cky Mountains. In the October 

 number (72) I gave a brief account of the methods now used iu ChH- 

 foruia and Nov York for keeping tlie fl n\v m th in cbeck, to»-*^her 

 with otber notes and observations. In the November issue (73) I 

 aunouucnd. the discovery of a new parasite ( Braam heheior Say) 

 of this insect, and added a new h^caUty. 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 CauMdian outbrt-ak are given. 



Mr, F. H. OhittendHin, As-istant Entomologist to the United 

 States Department of Atrriculture, in hu artitrle entitled "The 

 more Important I jsects Injurious to Stored Giain," gives a short, 

 somewhat popular account (71) of the Meiliterranean flour moth. 

 The article is illustrated, and contains the most perfect represen- 

 tation of the adult mo'h ever puhlished. 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 some valuable notes previously unpublished.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 Iwbefor Say feeding upon the lar\8e of the 

 Mediterranean flour moth, and furtht^r stated that I had bred a 

 single specimen, a male, from the same lot of larvae, which differed 

 in many respects from typical specimens of hcbeior, but was 

 thought by Mr. Aslimead to be a small vaiiety of the fame 

 species. B. gelecliae, although not found on the flour moth, is 

 mentioned, as it is closely related to B hchetor; and rt-ference is 

 also make to the European parasites of this inse(;t, B. brevicornis 

 and Chrymelus riihiginosiis. 



I note next a com au ici,tiou from a Pennsylvania miller, Mr. 

 E. Burns, who states (75) that he has been troub'ed wit'i the 

 fl >ur moth in his mill ft)r the last three years. He has been 

 fighting it, principally, by keeping an extra sweeper, which ad-is 

 about $500 per >ear 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 v^eather set in he could not 

 use this method, as the "steam on the cloths 'f the purifiers 

 makes all good middlings ru-n o>er the tail e"d of the machine." 

 This information adds a new locality for the flour moth, as it has 

 not heretofore been record d from Pennsylvania. 



Comments upon this outbreak and a few not'^s f^oncerning the 

 flour moth, with illustrations were pub'isl"^d (76) by me in 

 January, 1S96; and in Fe >ruary I rf>plied (78) to a query from 

 a milling firm in M-^lbourne, Australia, who iiad forwarded me 

 for examination a sample of flour matted together iu a way to sug- 

 gest the work of thn flour mot.h. No insects wt^re found in it. 

 An illustration accompanying my reply shows a sample of wheat 

 flour felted together by the flour moth.
