78 ANNALS OF SCOTTISH NATURAL HISTORY 



Dr. Sharp (" Coleoptera of Scotland") gives a list of 88 

 species of water-beetles for the Solway district, and also 

 mentions two species, Hydroporus dorsalis, F., and Copelatus 

 agilis, F., as having been recorded, but as being doubtfully 

 Scottish. 



These species were both said to have been taken by the 

 Rev. Wm. Little at Raehills, Dumfriesshire. The former 

 species has apparently never turned up in Scotland since 

 Little's time, but with regard to C. agilis there is a specimen 

 in the Dublin Museum Collection labelled " Oueensberry 

 Hill," M'Nab ! Now Queensberry Hill is within a few 

 miles of Raehills, but it seems probable that M'Nab's speci- 

 men is not the one recorded by Little, because the date of 

 Little's list containing his record is 1838, while the dates on 

 M'Nab's specimens in the Dublin Museum where, so far as 

 I know, is all that remains of his collection all run in the 

 sixties and seventies, where any dates are given. This 

 species has been recorded from England as far north as 

 Lanes S., and Yorks N.E., S.W., and Mid W., but there are 

 apparently no records for Cumberland or Northumberland, 

 and the Dumfries records are the only Scottish ones. 



Of the 88 species recorded by Dr. Sharp I have so far 

 failed to find I 2. These are : Haliplus striatus, Sharp ; 

 Ccelavibus confluens, F. ; Deronectes latus, Steph. ; Lacco- 

 philus intermptiis, Panz. ; Gyrinus suffriani, Scriba ; Berosus 

 l/iridus, L. ; CJicetartJiria seminulum, Herbst. ; Helophorus 

 nubilus, F. ; Hydr<zna testacea, Curt. ; H. angustata, Sturm. ; 

 H. atricapilla, Wat. ; H. pygmcea, Wat. 



Although I have worked both the Kelton and Caer- 

 laverock salt marshes on numerous occasions I have not 

 succeeded in finding H. striatns, Sharp. Sharp's record of 

 Ccelanibns confluens t F., is apparently founded on a " Rae- 

 hills " record given by Andrew Murray. This latter author 

 also recorded the species for Renfrew and Stirling. The 

 Dumfries record is supported by the fact that Lennon (MS. 

 List) mentions having taken one specimen in a brackish 

 pool in Caerlaverock salt marsh, - - a somewhat strange 

 habitat for the species ? and one specimen is to be found 

 in his collection, although it stood there as C. versicolor, 

 Schall. I have never been fortunate enough to find
