 On sending further specimens Prof. Westwood wrote,

 specimens I received from M. Lefebvre many years ago, 

 sent to him by Dr. Hammerschmidt, of Vienna." 



I further forwarded specimens and full details to 

 Prof. W. Saunders, President of the Entomological 

 Society of Canada, whose entomological position is too 

 well known to require any observation from myself, and 

 who was eminently qualified from personal scientific 

 and practical knowledge of the attack to offer an 

 opinion, and from him I received the statement : — 

 " The wheat-stem pests, enclosed in your letter, which 

 are embedded in the stalks of the wheat, are without 

 doubt the true Hessian Fly in its pupal condition, 

 known as the flax-seed state." I may add that in his 

 presidential letter to the Entomological Society of 

 Ontario, recently delivered by Prof. Saunders, he officially 

 announced the appearance of the Hessian Fly in Great 

 Britain from my specimens and details, my letter of 

 detail being read by Mr. James Fletcher, the Consulting 

 Entomologist of the Department of Agriculture of the 

 Dominion. 



In regard to development of the imago and determi- 

 nation of the same : — On the 8th of September an 

 excellent specimen developed. By forming a long wand 

 of twisted paper and moistening the tip with a little 

 chloroform I secured the imago without injury, and
