stems with the puparia of the Hessian Fly, commonly known in this 

 country as flax-seeds, still adhering to the stem beneath the sheathing- 

 leaves. 



Mr. Schoyen's commanication, sent from the Zool. Mus., Univ., 

 Christiania, on the 19th of Oct., was as follows : — " I hope that it will 

 be of some interest for you to know that the ' Hessian Fly' (Cecidomyia 

 destructor) is now, for the first time, observed here in Norway doing 

 damage upon Barley. I send you herewith some small bits of Barley 

 stems with tbe ' flax-seeds,' or puparia, of this insect that you may 

 ascertain the fact. As I am told, the damage on the concerned locality, 

 Kingerike, was last year much greater than this summer, at least one- 

 quarter of all the Barley stems having then been ' elbowed ' down by 

 the insect ; but then I knew nothing of the matter. Having been 

 informed this summer of the presence of some noxious insect in the 

 Barley stems on the named locality, I visited the place in the middle 

 of August, and found some of the maggots and puparia of the Hessian 

 Fly between the sheaths and stems of the damaged Barley plants. It 

 is thus made evident that this noxious insect is now introduced even 

 to our country, probably with foreign seed corn ; though I hope this 

 insect will not prove so fatal to us as in more southern countries. 

 Preliminarily I have recommended the burning of the infested screen- 

 ings and fall-ploughing of the land instantly after harvesting." — (W. 

 M. S.) 



Under the careful attention which is being given, there is good 

 hope of the recurrence of the infestation to a severe extent being well 

 held in check.
