THE AQUATIC COLEOPTERA OF THE SOLWAY DISTRICT 223 



O. lejolisii, Rty. and Muls. — Kirkeudbright, Douglas Hall, but 

 probably to be found at every suitable habitat. 



Hydr^ena testacea, Curt. — Kirkcudbright, R. Cairn near Irongray 

 (Sharp and Lennon). 



H. riparia, Kiig. — 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. angtista for the Solway 



H. angustata, Sturm, f 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. pygmaea, 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
