but burning these screenings will destroy the innumerable host of 

 " flax-seeds," which are shaken out of the straw when threshing. 

 Farmers appeared most desirous of learning all they could about 

 tliis pest, and I would most respectfully suggest to Her Majesty's 

 Board of Agriculture, the advisability of having printed a large 

 number of illustrated sheets of the Hessian Fly, &c., sending 

 them to the various County Councils for free distribution to 

 the fhrmers. 



I am continuing my experiments with the parasites, and 

 have, with the kindly co-operation of Dr. C. V. Riley, introduced 

 our Semiotellus nigripes into the United States, and hope to do 

 the same for other countries now infected with the Hessian Fly, 

 as no doubt these parasites are the best friends the farmer could 

 have for keeping in check this pest.

DEILEPHILA EUPHORBIA^: IN ENGLAND. 

 By Rev. J. Seymour St. John, F.E.S. 



In the interests of entomology as well as of truth, it is, I 

 think, necessary to lay before your readers the testimony of Mr. 

 F. J. Hanbury and Mr. J. Fry (the captor), as to the finding of 

 larvae of D. euphorhice in 1889, which I recorded in the 'Entomo- 

 logist.' My reason for doing so is this: — Seeing in the July 

 (last) number of the ' Entomologist's Record ' that Mr. Tutt 

 stated that the species had not been taken in this coantry for 

 some "three-quarters of a century," "with the exception of an 

 occasional immigrant," I wrote to his magazine reminding him 

 of the above capture. Neither my letter nor even an acknow- 

 ledgment of it appeared in the August number. I wjote to Mr. 

 Tutt on the subject, and in the September number appeared my 

 letter with a long note appended by Mr. Tutt, in which he 

 impugns, with exceedingly bad taste, the veracity of Mr. Fry. 

 That your readers may judge for themselves, I give in full what 

 is written in the September number of the ' Entomologist's 

 Record ' together with letters written by Messrs. Hanbury and 

 Fry. 



From the 'Entomologist's Record,' vol. iv., pp. 248 — 249: — - 



" Deilephila euphorbia. — 1 read in the ' Current Notes ' of this 

 magazine for July, 1893, the following statement : — ' D. euphorhice, 

 with the exception of an occasional immigrant, has not been British 

 for some three-quarters of a century.' Is this quite correct ? I beHeve 

 the ' perfect insect ' has not been taken in this country, but larvae have 

 been found. A young friend of mine found, in the autumn of 1889, 

 thirteen nearly full-fed larvae on the West of Cornwall, feeding on
