THE AQUATIC COLEOPTERA OF THE SOLWAY DISTRICT 147 



Fowler records this species as having been taken commonly 

 by Crotch at Liverpool, but it seems to have disappeared 

 from the modern Lancashire Lists. There is, however, a 

 specimen in the Chitty Collection at Oxford labelled " Liver- 

 pool, Power ! " Except for this record and one or two 

 inland ones, e.g. Derby and Oxford, which, considering that 

 the species is distinctly maritime, must surely be wrong, 

 the range of the species, as at present known, is entirely 

 south-eastern, from Hants S. to Norfolk E., but not recorded 

 for either Essex or Suffolk. The species also occurs in 

 Ireland, and has been taken in Co. Down by the late Mr. 

 Buckle and by myself. 



I first took a single specimen of Octliebius auriculatus, 

 at Kelton, in June 1906, and I found it there again in 

 August 1907. I did not, however, recognise it then, as 

 I had not seen the species and thought my specimens were 

 O. rufimarginatus, Steph. So far, I have only taken 5 

 specimens, but I found 3 specimens in the Lennon Collec- 

 tion mixed with O. bicolor, Germ. This species has only 

 been recorded from Sussex E. and Kent E. in England,

but it has been taken in Cos. Meath and Dublin in Ireland. 1 

 Octhebius lejolisii, I only discovered in the Solway 

 district in October last. When in Dublin, at the British 

 Association Meeting, Professor Hudson Beare and I went 

 to Dalkey on Mr. Halbert's instructions to find this species 

 in the rock pools. After vainly searching for a considerable 

 time, we at last found it in very small holes of clean salt 

 water, and with the imagines we found the larvae. The 

 pools were just above high-water mark and held a pint or 

 less of water. At high tide they were splashed by the sea, 

 as we found to our cost. The sea was just settling down 

 after a violent storm, which would perhaps account for the 

 fact that the water in the pools appeared to be pure sea- 

 water. Having once discovered the beetles walking on the 

 sides and bottoms of the pools, they were not difficult to 

 find. After the British Association Meeting I went to 

 West Donegal, and there, both at Dunfanaghy and at 



The species occurs as far north as Borkum Island on the west coast of 

 Europe. Since going to press I have seen specimens from Lines N. (Rev. A. 

 Thornley), so, possibly, the species occurs all up the east coast of England.
