AFTER A. 



BY PROF. GEO. H. CARPENTER, B.SC, M.R.I.A. 



Our investigation of the Springtails and Bristletails of the Sligo district 

 was rewarded by the discovery of ten species of the former group, and 

 one of the latter. So little is yet known of the distribution of these tin)' 

 insects in Ireland that records of even the commonest species ar 

 valuable. But it is gratifying to find that one of the Springtails taken 

 on the shores of Lough Gill has not hitherto been noticed in the British 

 Islands. This species, Xenylla brevicaiida, Tullberg, has a distinctly northern 

 continental range, and falls naturally, therefore, into a faunistic group 

 most characteristic of the neighbourhood of Sligo. 



The following are the species obtained : — 



IVIachilis polypoda, Linn.— Strandhill, Carrowmore, Lough Gill. 



Sminthurus vlridls, Linn. — Ballysadare. 



S, luteus, Lubb.— Strandhill. 



Orchesella cincta, Linn. — Lough Gill shore. 



Tomocerus tridentlferus, Tullb. — Lough Gill shore. 



Lepidocyrtus lanuglnosusj Gmel.— Lough Gill shore.
