it occurred in the marshes, now nearly all destroyed, on 

 the Braid Hills. 



My localities and dates for it are — 



Braid Marshes, 1873; near Penicuik; Loganlea, Pentlands, 9, 27th May 

 1895 ; Bavelaw Moss, June 1895, and 29th and 30th May 1900, fairly common ; 

 15th May, S, 27th May and 3rd July 1901, common; June 1904, a good 

 many; meadow near Kirknewton, 7tli and 10th July 1900, several; New- 

 park, June 1895; Drumshoreland, June 1895 and July 1904, a few; near 

 Torphichen, 15th June 1895; pond near Cullalo, Fife, June 1900; Duchray, 

 near Aberfoyle, 27th May 1896; Trossachs Road, Aberfoyle, June, several, 

 and <J, 27th July 1900. 



Ischnura elegans (Lind.). 

 This, the smallest species we find here, is very widely 

 distributed, and common locally. Unlike the last, it avoids 

 the moorlands, preferring sedgy and weedy ponds, dams, and 

 deep ditches to peat-pools. I have taken it in the following 

 localities : — 



LufFness Marshes, Aberlady, June 1890, July to 9th Aug. 1898, and 16th 

 June 1900, a good many ; Duddingston Loch, at the curling-pond, 26th July 

 1900, and 4th July 1902, abundant; marl-pit, Davidson's Mains, July 1900, 

 a few; Malleny Dam, Balerno, July 1901; canal, near Ratho, Aug. 1903; 

 Drumshoreland curling-pond, June 1895, July 1900, and July 1901, common; 

 Kilconquhar Links, June 1897 ; Otterston Loch, July 1901 ; Culross, July 

 1900; mill-pond, Bridge of Allan, 28th June 1901, common; Loch Ard, 

 July 1900, common. 



Agrion puella (Linn.). 



A. puella, Evans, Ann. Scot. Nat. Hist., 1900, p. 125, and Ent. Mo. 

 Mag., 1900, p. 88. 



While common in the greater part of England, the true 

 Agrion puella appears to be a rare insect in Scotland. The 

 only occasion on which I have taken it was on 22nd June 

 1896, when I found a few flitting about an old clay-pit 

 at Bush, near Eoslin, county of Edinburgh, as recorded in 

 1900 {loc. cit.). The name puella appears in Stewart's Edin- 

 burgh List (1), but the record is of doubtful application, 

 for several forms — including the next — were then covered 

 by that name. De Selys (5) seems, however, in 1845 to 

 have identified both ijuella and cyathigeruni from " Scotland " 

 in Greville's collection. 



The distribution of these small blue-bodied species in 

 Scotland is much in need of investigation.
