THE AQUATIC COLEOPTERA OF THE SOLWAV DISTRICT 223 



O. lejolisii, Rty. and Muls. Kirkcudbright, Douglas Hall, but 

 probably to be found at every suitable habitat. 



Hydrasna testacea, Curt. Kirkcudbright, R. Cairn near Irongray 

 (Sharp and Lennon). 



H. riparia, Kug. Dumfries, Kirkcudbright, Wigtown ; common 

 in grassy ponds and grassy edges of rivers. 



H. britteni, Joy. Kirkcudbright, Cargen Burn, very common in 

 March 1907 on some flooded meadow land. Wigtown, R. 

 Cree, one only. These are the only times I have found the 

 species in the Solway district, but I have taken it in Ayrshire 

 and Renfrewshire. 



H. longior, Rey. \ Dr. Sharp records H. angusta for the Solway 



H. angustata, Sturm, j district. It seems doubtful whether that 



species really occurs in Britain, the records apparently referring 



to H. longior (E. A. Newberry, "EMM." ser. 2. xviii. 172-3, 



1907). 



H. gracilis, Germ. Kirkcudbright ; common in almost all the 

 small streams I examined. 



H. atricapilla, Wat. Kirkcudbright, R. Cairn, near Lincluden 

 (Lennon). 



H. pygmasa, Wat. Solway (Sharp). 



H. pulchella, Germ. Kirkcudbright, R. Nith. Lennon also men- 

 tions having taken one specimen in the Glen Burn (Cargen 

 Burn). Scarce. 



Cyclonotum orbiculare, F. Dumfries, " abundant in flood-refuse " 

 (Lennon) ; Kirkcudbright, Maxwelltown Loch. 



In the foregoing list I have endeavoured in mentioning 

 localities to use only names to be found on the map, and 

 the map which I have followed is Bartholomew's " half-inch." 

 Lennon's reference to the " Glen-mill burn " refers to the 

 Cargen Burn or Cargen Water, and if I have incidentally 

 mentioned " Lotus Loch," it is the same as Loch Arthur. 

 " Racks Moss " is that part of the Lochar Moss near Racks 

 Railway Station, an easily approached part of the moss, and 

 usually very productive. Similarly, " Bankend " refers to that 

 part of the Lochar Moss near the village. 



I have already mentioned how the personal element 

 affects the results of any collector, so that my remarks as to 

 the commonness or rarity of a species are quite probably 

 unjustifiable. In such a district as the south-west corner of
