THE AQUATIC COLEOrTERA OF THE SOLWAY DISTRICT 149 



recorded for Scotland (Berwickshire, Andrew Murray, 1853). 

 There is, however, a single specimen of this species in the 

 Dublin Museum Collection labelled " Royal Botanic Garden, 

 Edinburgh, 1 864 " (M'Nab). I only found the species at 

 one spot on the river Dee, Kirkcudbrightshire, where, how- 

 ever, it was distinctly common. It occurs in Northumber- 

 land, Durham, Yorks, and Lanes S., but has not so far been 

 recorded from Cumberland, so that the northern counties of 

 England and the southern counties of Scotland would appear 

 to be its northern limit in Britain. 



The other record of interest is Rhantus pulverosus, Steph., 

 of which, however, I only took one specimen ! The only 

 other Scottish record is one of Little's, for Forfarshire, which, 

 however, Dr. Sharp regarded as doubtful. It has been taken 

 in Lanes S., and Durham, so that possibly my single speci- 

 men should be regarded as an individual which has exceeded 

 the normal bounds of distribution of the species. 



When Canon Fowler published his book on the " British 

 Coleoptera" (1887), Agabus affinis, Payk, was only known 

 to occur " near Dumfries." Whether the species has since 

 rapidly increased its range, or whether the absence of other 

 records at that time was due to confusion with A. unguicul- 

 aris, Thorns., it is impossible to say, but the species is now 

 very widely distributed in Great Britain, and occurs also in 

 Ireland. 



It had been previously recorded for " near Glasgow," 

 Andrew Murray, 1853 ; Renfrewshire, "local but very 

 abundant," Morris Young (" Ent. Weekly Intelligencer," 

 i. 1 66, 1856); and Fifeshire, Andrew Murray, 1853; but 

 these records had all been swept aside by Dr. Sharp, who 

 said " specimens of A. ungiiicularis have usually been mis- 

 taken for this species" ("Col. of Scotland," 1871-78). 



At the time of the publication of my paper on these two 

 species ("Ent. Rec.," xviii. 1906), A. affinis had been re- 

 corded from Clackmannan (A. Beaumont, " Scott. Nat," ix. 

 1887-88); Warwickshire (H. Willoughby Ellis, "Viet. 

 County History," 1904); Edinburgh (Wm. Evans, "Ann. 

 Scott. Nat. Hist," ix. 91, 1900 (taken in 1896), and T. H. 

 Beare, "Ent. Rec.," xv. 49, 1903); and Berwick (T. H. 

 Beare, "Ent. Rec.," xv. 181, 1903); and I have since found
