I920. Johnson. — Some Irish Sawflies. iii 



has a boring apparatus. None of them have anything in 

 the shape of a sting, and they are quite unable to hurt a 

 human being. Sirex gigas' is often mistaken for a hornet, 

 but it is quite different in colour and shape ; besides, we 

 have no hornets in Ireland. The larvae of Sawflies being 

 vegetable feeders, sometimes do harm, as in the case of the 

 larva of the Gooseberry Sawfly. The Pine Sawfly often 

 does harm on the Continent, but here it is happily somewhat 

 rare, though cases have occurred of its doing damage, as 

 reported by Mr. Praeger^ and Professor Carpenter.^ 



I have received much kind help from the Rev. F. D. 

 Morice, M.A., F.E.S., who assisted me with my difficulties, 

 and whose " Help Notes have been invaluable to me, 

 forming, as they do, a most admirable guide to the study of 

 the British Tenthredinidae. I have followed the nomen- 

 clature and arrangement of the " Help Notes," except as 

 regards the genus Tenthredopsis, which is still in considerable 

 confusion. However, Mr. Morice has kindly given me the 

 latest arrangement, which even so is still more or less pro- 

 visional. 



In the following list I only give those species which I 

 have collected myself, or which have been sent me by friends, 

 omitting those which I collected for the Clare Island Survey, 

 which have been already published by Mr. Morley. 



I have placed after each species the month in which it 

 occurred, and it will be seen that May and June are the 

 months in which I have met with most species. 



Of the localities mentioned below, Poyntzpass, Jerretts- 

 pass, Drumbanagher, Glenanne, Keady, and Churchill are 

 in Co. Armagh ; Caledon, in Co. Tyrone ; Tempo, in Co. 

 Fermanagh ; Coolmore, Coxtown, St. Ernan's, and Portnoo, 

 in Co. Donegal ; Cave Hill, in Co. Antrim ; Groomsport, 

 Dundrum, Newcastle, Newry, Banbridge, and Lough Shark, 

 in Co. Down ; CarHngford, in Co. Louth ; and Rosses Point, 

 in Co. Sligo.
