and is thus very liable to be overlooked. Ilyocryptus sordidus 
has been obtained in three localities within the district around 
Edinburgh, viz., Lochend Loch, where it was common ; Loch 
Leven; and ina ditch by the side of Harelaw Dam,—the first 
and last localities are in the vicinity of Edinburgh. I have 
also records of its occurrence in Loch Morar, Inverness-shire; 
Loch Tay, Perthshire; and in a small loch near Rutherglen, 
Lanarkshire. Greenock (M. F. Dunlop).

Eurycercus 18 comparatively a commen species. I have 
obtained it in Duddingston Loch, Raith Lake, Lochgelly
