THE AQUATIC COLEOPTERA OF THE SOLWAY DISTRICT 219 



A. affinis, Payk. — Dumfries, Kirkcudbright, Wigtown. Fairly 

 common, but localised so that it may occur in only two or 

 three pools on a large peat moss, and in those pools it will 

 be common. Both this species and the next are usually in 

 mossy patches, and often do not turn up in the net until the 

 pool has been thoroughly disturbed. 



A. unguicularis, Thorns. — Kirkcudbright, Maxwelltown Loch and 

 three other spots ; often with A. affinis, but whereas that 

 species seems to specially favour Sphagnum, imguicularis is 

 more common in Hypnum, and the pools therefore are more 

 grassy. Fairly common in the four localities where it has 

 been found. 



A. congener, Fayk. — Dumfries, Kirkcudbright, Wigtown ; peat 

 mosses at quite low altitudes and in company w^ith A. affinis. 

 In other parts of Scotland I have always, so far, found this 

 species on mountains. Not common but widely distributed. 



A. nebulosus, Forst. — Kirkcudbright; a "pond" species, but 

 occasionally found in peat-moss holes even at high altitudes, 

 e.g. Criffel top. Also common on salt marshes, giving place in 

 more brackish pools to A. conspei'sus. 



A. conspersus, Marsh. — Dumfries, Caerlaverock Salt Marsh 

 (Lennon) ; Kirkcudbright, Preston INIerse, common in such 

 localities. 



A. femoralis, Fayk. — Dumfries, near Moffat (Lennon); Kirkcud- 

 bright, Rockcliffe. Lennon only found it in one pond near 

 Moffat Well, and I only found it in one pond at Rockcliffe. 



A. arcticus, Fayk. — Dumfries, near ]\Ioffat, one specimen (Lennon); 

 Kirkcudbright, on the side of the Rhinns of Kells, 700 feet 

 up, one specimen. Excepting Criffel, I have done no 

 mountain work in the Solway district. The species is usually 

 alpine and probably occurs on the high grounds of the 

 district, although it does not seem to occur on the Criffel 

 range. 



A. sturmii, Gyll. — Dumfries, Kirkcudbright, Wigtown; fairly 

 common but somewhat local. 



A. chalconotus, Fanz. — Dumfries, Kirkcudbright, Wigtown; peat 

 mosses, fairly common. 



A. bipustulatus, Z. — Dumfries, Kirkcudbright, Wigtown. 



Platambus maculatus, Z. — Dumfries, Kirkcudbright; a running- 

 water species, and common. Almost certainly occurs in 

 Wigtownshire, although I seem to have missed it. 



P. maculatus, var. immaculatus. Doiinisth. — Kirkcudbright, R. Nith, 

 R. Urr.
