In his Rpport for 1890 (37) Mr. Fletcher reviews his previous 

 account of Ephestia kuehnielUi, and quotes several importaut let- 

 ters from the mannger of the first infested mill. The indifference 

 on the part of those most interested is very noticeable, for one 

 would naturally suppose that millers and produce dealers would 

 have taken a little trouble to understand this matter, and to assist 

 in carrying out measures which would be for their special benefit. 

 A great many millers suffered severely for thinking there was 

 nothing to fear when the moths first appeared on their premises. 

 Mr. 'Fletcher says, "the steps taken by the Provincial Board of 

 Health, and the milling company on whose premises the moth 

 worked such havoc in 1889, have proved very satisfactory and 

 were entirely successful. A few straggling moths were seen in 

 the mill during the summer of 1890, but constant watching and 

 scrupulous cleanliness finally rid the mill of the infestation." Mr. 

 Fletcher gave an earlier account of this outbreak in Canada in a 

 Eeport of the Entomological Society of Ontario (30). 



The appearance of this moth in North America in 1889 in such 

 destructive numbers called forth a timely article by- Dr. C. V. 

 Eiley and Mr. L. O. Howard (27), in which the known facts 

 regarding this pest are brought together in a condensed form.* 

 Mr. Howard visited the Canadian mills the latter part of August, 

 1889, and accompanied Mr. Fletcher on a tour of inspection to 

 the worst- infested establishment. The entire building was still 

 completely overrun by this insect, notwithstanding the thorough- 

 going measures which had been taken for its destruction. The 

 principal studies on kuehmella mentioned in this article were, 

 however, made upon material brought to Dr. Riley by Professor 

 Panton, of the Guelph Agricultural College, during the summer 

 of 1889; on material in the National Museum, containing speci- 

 mens from Eufaula, Ala.; on five specimens from Europe gent by 

 Mr. Ptagonot; and on others from Germany, forwarded by Pro- 

 fessor Zeller in 1883. The various stages of Ephestia inierpnnc- 

 iella are figured in comparison with those of kuehniella, in order 

 that both may be readily recognized, the early stages being quite 

 similar. 



In his excellent monograph of the North American Phycitidse 

 (36) Mr. G. D. Hulst cites some of the literature of Ephestia 

 kuehniella and a short description of the species, indicates its 

 distribution, and says that his specimens from New Mexico were 

 taken in August and September. He refers to Zeller's original 

 description and to Dr. Bryce's pamphlet, and quotes several par- 

 agraphs from the latter. 



In August, 1892, Prof. T. D. A. Cockerell, then of the In- 

 stitute of Jamaica, reported the appearance of this insect in Kings- 

 ton, Jamaica. He found some oatmeal badly infested with larvae 

 which he sdipposed to be those of the Mediterranean flour moth, 

 and accordingly issued a circular letter giving a short history of 

 this pest, which was afterwards published in several daily papers 

 in Kingston (40). April 1, 1893, Prof. Cockerell wrote me as
