the American Seniiotellus = Merisus destructor, I do not at all 

 see that the presence of this militates against the whole of the 

 attack being of European origin. 



In the works of Kollar and Kaltenbach on injurious insects 

 (to go no further) this parasite is mentioned under its synonym 

 of Ceraphron destructor, Say, as a German parasite, and therefore 

 it appears to me that the whole of our attack is extremely likely 

 to be of European derivation. 



For further information as to this special parasite (namely 

 the M. destructor) in our present difficulties, with list of 

 synonyms, the reader is referred to the paper on the " Parasites 

 of the Hessian Fly," by Prof. Kiley, published in the ' Proceedings 

 of the United States National Museum, 1885 ' ; and whilst I believe 

 I am permitted by both the distinguished entomologists to whom 

 I have alluded to mention the above results of investigation, at 

 which in the case of Prof. Riley I have had the advantage of 

 being present, I must also express my sincere thanks for such 

 great aid in this most difficult investigation.

NOTES ON SCOPARIA ANOUSTEA. 

 By W. G. Sheldon. 



This species has been until lately supposed to be a single- 

 brooded one, appearing in August and September, and hyber- 

 nating until the spring. Mr. C. G. Barrett, however (E.M. M. 

 xxii. 42), says : — "Last May, at Plymouth, when searching on 

 the old walls round the harbour, I found several larvffi of this 

 species full-fed, and also pupge. From these the moths emerged 

 after a few days. It therefore seems that this species produces 

 a spring brood on the south coast, when the winters are so mild 

 as to allow the larvae to feed through them, and this habit 

 probably obtains to some extent throughout the South of 

 England. I cannot, however, remember that I ever saw a 

 spring specimen at Pembroke, where the moth was abundant in 

 the late autumn." Mr. G. T. Porritt again lE.M. M. xxii. 209) 

 says that he took the species commonly at Huddersfield at the 

 end of July, and adds that he received young larvae from
