So ANNALS OF SCOTTISH NATURAL HISTORY 



Lincoln N. and Derby. There are several Scottish records 

 for ChcBtarthria seminuluin, Hbst., and I have taken the 

 species in Ayrshire, but, so far, not in the Solway district. 

 Helophorus nubilus, F., is recorded for various districts in 

 Scotland, but, unlike most of the other members of the 

 genus, it is more commonly taken on dry ground away from 

 water, so that it is perhaps not so surprising that I have not 

 come across it. 



Hydrcsna testacca, Curt., again, is commoner in the south 

 than in the north, though there are records for Cheshire and 

 Yorks S.W. and Mid W. Lennon (MS. List) mentions 

 having taken one specimen on the banks of the Cairn 

 (Kirkcudbright), but whether this is the record Sharp refers 

 to, I do not know. H. angustata, Sturm., should probably 

 refer to H. longior, Rey., as it seems doubtful if the former 

 species occurs in Britain (see Newberry, " EMM.," ser. 2, 

 xviii. 172-3, 1907). Although I have taken none of 

 the three, H. longior, atricapilla, or pygma>a, in the Solway 

 district, they are distributed throughout Scotland, and are 

 not uncommon. 



Sharp also mentions 19 species as probably occurring in 

 the Solway district, although at that time he had no records 

 of their occurrence. Of these I have found all except 6, 

 which are : Ilybius obsciirus, Marsh ; /. guttiger, Gyll. ; 

 Gyrinns distinctus, Aube" ; Helopliorus rugosus, Ol. ; Hydrochus 

 brevis, Herbst., H, angustatus, Germ. Lennon (MS. List) 

 records /. guttiger, but he evidently intended /. cenescens, 

 Thorns., so that species, Ilybius obscurus, and Gyrinns dis- 

 tinctus, have not apparently fulfilled Dr. Sharp's expectations. 

 Lennon, however, seems to have found both species of 

 Hydrochus, brevis being " common in marshy parts of Max- 

 welltown loch" (MS. List), while one specimen of angustatns 

 seems to have occurred at the same place (' Some Addits. 

 to Scottish Coleoptera,' etc., " Ann. Scott. Nat. Hist." April 

 1892 ; also MS. List.) In his collection is a very full series 

 of the former species (32 specimens), while there are two 

 specimens of the latter, one labelled Mid-Solway and the 

 other " Midlands." I have visited Maxwelltown Loch on 

 many occasions, but have never seen these species. Possibly 

 the conditions have changed so much that they have become
