DIAMOND-BACK MOTH. 99 



my astonishment at finding the species so abundantly last night. 

 Where do they come from ? I can scarcely think they would lie over 

 from 1892 in the egg or other state until this year." 



Somewhat later in June, I heard from Mr. S. B. Burroughes, of 

 Winton Hall Farm, Clay-next-the-Sea, Norfolk, mentioning that he 

 had seen the Diamond-back Moth on his marshes close to the sea early 

 in April, which, as he observed, appeared to him to favour the idea 

 that they came over the sea from some other country. Mr. Burroughes 

 was then having his Turnips dressed with soot and nitrate of soda to 

 push on growth, and particularly requested information as to any 

 better remedies, as the Diamond-back infestation had nearly ruined 

 his Turnip crop in 1892. 



On the 25th of June Mr. Burroughes, who was watching the 

 Turnip leafage most carefully for commencement of caterpillar attack, 

 further wrote me: — "I had one field of Turnips which were full of the 

 Diamond-back Moth, which I dressed with nitrate of soda and soot ; 

 and that and the unfavourable weather which prevailed a few days 

 back, has completely routed the enemy, and at present I cannot see 

 any." Mr. Burroughes added further in the same letter : — " I have 

 examined the under part of the Turnip-leaf very closely, but could 

 not, up to last Saturday, find any harm done ; the Turnips dressed 

 with nitrate of soda and soot are doing extremely well." — (S. B. B.) 



This report and the preceding one, it will be observed, relate to 

 appearance of the nintlis on the Norfolk coast. 



On the 11th of June Mr. S. L. Mosley, F.E.S., wrote me from 

 Huddersfield, Yorks : — " I see the Diamond-back is very abundant 

 here just now in the imago " {i. e., moth, Ed.) " state " ; and on the 

 27th of June the following note, sent to me by Mr. James Cooper, of 

 Killerby Hall, Scarborough, showed presence of the attack (like those 

 reported in Norfolk on the coast) to an amount calculated to cause 

 serious apprehension, which in this case was amply justified. 



Mr. Cooper wrote : — ** We are having another attack of the 

 Diamond-back Moth on the Turnips, and most farmers about here 

 have had to resow their crops. I am one of such, and write to you to 

 ask if you have any leaflets on the subject, as I wish to save my second 

 sowing if possible." On July 10th Mr. Cooper further wrote that the 

 infestation was on the increase, " and is clearing whole fields in these 

 parts of the young Turnips." 



On the following day (July 11th), Mr. Edmund Riley, writing from 

 The Weir, Hessle, Hull, remarked : — " The Diamond-back Moth has 

 also been very prevalent, especially along the coast near the sea." * 



* Great damage was also reported by Mr. Biley from the Turnip Flea Beetle ; 

 but this is independent of the Diamond-back mischief, Mr. Eiley being well 

 acquainted with both attacks.
