DIPTKRA. 



BY PKRCY H. GRIMSHAW, F.E.S. 



[The following short list of two-winged flies is the result of 

 very casual collecting while working other groups of insects. 

 A few of the species are uncommon, and are possibly here 

 recorded from Ireland for the first time. It may be of interest 

 to record the occurrence of the gnat Culcx pipie?is, L , in 

 abundance in the cave at Sunk Island. — J. N..H.]

HYMKNOPTKRA. 



BY J. N. HALBERT. 



With the exception of Bombus ttrrestris and the four species 

 of ants, the following Hymenoptera were recorded from 

 Lambay by Mr. H. Gore Cuthbert in the Irish Naturalist for 

 1896. 1 Ants are extremely abundant on the island, especially 

 the species of Lasius. Mr. E- Saunders has verified the 

 identification of the races of Myrmica.
