Great sioarms of Ephemeridce on Lough Neagh.—On one of my many visits to 

 Maghery, on the shores of Lough Neagh, I happened to he standing talking to Mr. 

 Eoss in front of his house. A steamer towing a barge had a little time before passed 

 out of the canal on to the lake. Looking towards Derrywarra Island, I remarked 

 to Mr. Koss that the smoke was taking a long time to clear off. He began to laugh, 

 and told me that what I thought was smoke was flies. I was incredulous, but, on 

 watching the appearance, saw that the apparent smoke, instead of blowing away, 

 moved up and down, spread and contracted, but still kept over Derrywarra ; in 

 fact, it was a vast collection of Ephemerce indulging in an evening dance. 



The same day, when on Coney Island, I was struck by the remarkable appear- 

 ance of the trees and shrubs with which the Island is covered. These were clothed 

 in spiders* webs, so that they were quite white looking, and the man who lives on 

 the Island told me that the spiders were always in great force at that time looking 

 out for the flies. 



The numbers of EphemercB were very great — the meadows along the Lough 

 shores were full of them, and the edge of the Lough almost blackened with the 

 bodies of those which had died. — W. F. Johnson, 2, The Seven Houses, Armagh : 

 November, 1885. 



Trichoptera from Belfast. — During a recent official visit to Belfast, my friend 

 and colleague Mr. Barrett kindly collected such Trichoptera as came in his way. A 

 list is here appended, with the idea that it may prove useful when Irish entomolo- 

 gists can work out a Trichopterous Fauna in the same manner as has recently been 

 done for Scotland by Messrs, King and Morton in the pages of the " Scottish 

 Naturalist." 



Limnophilus marmoratus, Curt., lunatus, Curt., and sparstis, Curt., and Stem- 

 fhylax concentricus, Zett., all at gas lamps in Belfast ; Silo pallipes, F., Colin Glen ;

FOIJETEENTH EePOET OF THE StATE ENTOMOLOaiST ON THE NOXIOUS AND 



Beneficial Insects of the State of Illinois. Third Annual Eeport of S. A. 

 FoBBES, year 1884. Springfield, Illinois, 1885. 



Mr. Forbes is the indirect successor (Drs. Le Baron and Cyrus Thomas inter- 

 vening) to the late gifted B. D. Walsh, as State Entomologist for Illinois, and as a 

 notable feature in this Eeport he has been at the trouble to compile a general Index 

 for the whole series, which will be very useful to those who are so fortunate as to 

 possess the whole. The present volume is based on the same plan as is usual in 

 Amferican State Eeports, and shews an amount of care and minute observation equal
