King and Hai.bert — A List of the Neuroptera of Ireland. 31 



It has been found necessaiy to thoroughly revise the species of Perlidae 

 (Stone-flies) in the light of tlie recent researches of Morton, Kempny, ami 

 others. We hope the present short list, containing several additional species* 

 will serve as an accurate basis for future work in this country. 



In the group Planipennia (Alder- flies, &c.), eight species have been 

 added to the Irish list. Undoubtedly the most notable discovery is that of 

 Pscctra diptera in County Wexford, an insect of great rarity in the Britannic 

 area, where it is now known to have been found in three localities ; and it 

 seems almost equally rare both in Europe and America. The apparent 

 absence from Ireland of certain conspicuous British insects belonging to this 

 group is noteworthy ; we may refer to the genera Ehaphidia (Snake-flies) 

 and Nothochrysa as examples. Of interest, also, is the recent capture in 

 County Cork of one of the Scorpion-flies, Panorpa ycrmunica, the first 

 recorded occurrence of these insects in Ireland. 



Eleven species of Trichoptera (Caddis-flies), some of considerable rarity, 

 have been added. There is little doubt that fresh discoveries await the 

 assiduous collector of these interesting insects, especially amongst such small 

 forms as are contained in the family Hydroptilidae. 



For convenience of reference, we give here the names of the various 

 species which have been added to, or deleted from, the 1889 list. They are 

 as follows : —
