 altogether sixt}- species of water-beetles, a conclusive proof 

 of the richness of the localit}'. There is one species whose 

 capture I have not yet mentioned, but which was about the 

 most interesting of all wx took. This is Hyd?opor2is dorsalis, 

 F., a species which I had never met with anywhere about 

 Armagh when I was there, and the first record of which for 

 Ireland is to be found in the Supplement to the List of Irish 

 Beetles b}^ Mr. Halbert and myself, where it is noted as having 

 been taken by the late Mr. B uckle in the Lagan Canal near Moira. 

 Mr. W. H. Patterson, M R.I. A., took it next on November 17th, 

 1903, in a quany at Gilnahirk, near Knock, Co. Down, as 

 recorded by me in the Irish Natu) allst ^ vol. xiii. (1904), p. 93. 

 He took it again in the following August in the same place. 

 I have seen a specimen captured b}" Mr. J. N. Halbert, 

 M.R.I. A., at Tonabrocky, Co. Galway, in September, 1905, so 

 that it has now been found in the extreme west and in the 

 north-east of Ireland. There is but one record for Scotland, 

 '' Raehills, Rev. W. Little," which is given with reserve by 

 Canon Fowler,^ and Mr. Balfour Browne tells me that he knows 

 of no recent capture yet in that countr}^ In England it is 

 widelv distributed and occurs in the Northumberland district. 

 Dr. Sharp- gives its range as " Northern Europe and Siberia 

 (Sweden ; Finland to 68^ 10' North; Sahlberg; Britain, France, 

 Germany)." The remarkable thing about this beetle is that 

 thirteen years ago it was most certainly not to be found about 

 Armagh, yet now it is present in profusion, for we took it in 

 the quarries, in the drains, and in the ponds plentifully. The 

 point to be elucidated now is. from whence is H. dorsalis 

 advancing ? 



I did nothing at Lepidoptera during the autumn, but a ver}' 

 fine specimen of the Death's Head Moth {Achero7itia atropos) 

 was brought to me in October, which had been found lying
