So ANNALS OF SCOTTISH NATURAL HISTORY 



The other southern representative in the Mid-Ebudes is 

 Octliebius lejolisii, Rey and Muls. I found it on Coll in the 

 usual situation, small rock pools, but I did not look for it in Mull. 

 I also found it in Argyll Main, near Oban, but in both 

 places it was very much scarcer than in the Solway district 

 or in Ireland, in fact, except for a few larvae, I only found 

 about five or six specimens altogether. This scarcity 

 suggests that the Mid-Ebudes district is about the northern 

 limit of its range. The known range of the species is from 

 the Isle of Wight, where Donisthorpe has recently taken 

 it, to Coll. In Ireland I have taken it at various places 

 between Dublin and Mayo W. round the East, North and 

 West coasts, and it probably occurs all round the island. 

 There is at present no record of the species for the east of 

 England or Scotland, but very few collectors have, I believe, 

 so far found the species at all, so that it may yet occur 

 along the North Sea border. 



I took 47 species on Coll and 36 on Mull, the total 

 number of species being 56. Out of the additional 9 

 species found in the latter island, 8 belong either to the 

 mountain group or to the running-water group. I have 

 considered Agabus congener, Payk., as a mountain species, 

 although it often occurs at low altitudes, e.g. almost at sea- 

 level in the Solway district, but in such cases it is usually 

 in a mountainous district. There are, however, two 

 specimens in the Chitty Collection at Oxford, one labelled 

 " Sunningdale " (Berks), and the other " Belvedere " (Kent 

 W.), and until quite recently I have regarded these two 

 specimens as having been wrongly labelled. Dr. Sharp 

 has now discovered the species, actually in company with 

 Agabus brunneus, F., which is a southern species, in the New 

 Forest (Hants S.), so that the Berks and Kent W. records 

 are probably correct. Except for these three records the 

 species has apparently not occurred in England south of 

 Yorks Mid W., although there are one or two records, 

 e.g. Norfolk and Suffolk (Stephens), which have been 

 supposed to be erroneous. 



Although I visited the crater tarn above Tobermory 

 I failed to find either imago or larva of Dytiscus lapponicus, 

 Gyll., but this may have been due to the fact that a very
