90 The Irish Naturalist. August, 



tidal Broad Lough, T. striatum greeted me at almost every 

 suitable spot, while a little north of the footbridge across 

 the river it is abundant. I assume this spot is Dr. Scully's 

 station for T. glomeratuni, but neither on this nor on a 

 previous visit with Mr. G. E. C. Maconchy in 1921 could 

 I find this species. T. scahrum I only saw on a raised 

 bank a short distance south of Newcastle, between the sca 

 and railway, where it was quite dominant for a few yards. 



Discovered, respectively, by A. G. More in 1867 and by 

 Dr. David Moore in 1869, T. suhierraneum and T. glomeratuni 

 appear to have been generally regarded as aliens.^ 



At present I could see no reason for such a suggestion 

 as none of the ordinary weeds of cultivation occur with 

 them and the ground is covered with Scilla verna ; moreover 

 they are corjspicuously absent from the disturbed ground 

 along the railway where the aliens congregate. Car ex 

 Pseudo-cyperus still lingers in Dr. Moore's station near 

 Newcastle but seems nearly extinct, only a few plants 

 being seen by the road, half a mile west of the station. 



Amongst the Bees the beautiful little Osmia aurulenta 

 occurred in hundreds between Killoughter and Newcastle 

 along the railway banks. This species I added to the 

 Irish list last year from The Island, Malahide. Amongst 

 other captures was a male Humble Bee (Bomhus lucorum), 

 the presence of which at such an early date in a late season 

 is surprising and, had it not been in good condition, might 

 have given rise to the quesdon : — " Can a male survive 

 the winter by hibernation " ? 



Of the Fossores or Digging Wasps I was glad to find 

 a large Ammophila, almost a giant among our species, 

 being more than an inch in length and across the wings. 

 Freke captured two specimens on the sands at Arklow 

 many years ago, which he recorded in this Journal (vol. v., 

 p. 40) as A. hirsuta, but one of his specimens in the National 

 Museum is A. lutaria, a closely allied but apparently rarer 

 species in England. 



1 I find I am mistaken. See A. G. More in "Recent Additions," 

 p. 5, 1872, where both plants are stated to be " undoubtedly native." 

 It would appear lo have been the editor of Cyhele II. who first and last 

 regarded them as aliens.
