4 THE ENTOMOLOGIST. 



Salda elecfantida, Fall. — A minute species much smaller 

 than the last, occurring in the saltmarsh, but under different 

 conditions. It lives further into the marsh amongst the tangle 

 under the Sea Lavenders {Statice limonium et S. haJtusiensis). It 

 seems to shun the barer spots. Almost the only insects accom- 

 panying it are Agdistis hennelii and Orthezia artica. 



Salda morio, Zett. — An Alpine insect very abundant around 

 Whitfield Lough in Northumberland. This is a small mountain 

 lake with a very rocky bottom and shores, situated at a height 

 of about 2000 ft! on Whitfield Fell. The lake is almost without 

 an aquatic flora, probably on account of its open situation and 

 its incessant motion. The bug occurs amongst the boulders on 

 the shore. The only other insects considered worthy of note 

 there were the mitltitudes of Larentia aesiata of all shades and 

 a few caddis flies {Phygajiea grandis). The vegetation around it 

 was interesting, firstly because of the abundance of the Cloud- 

 berry {Bubus diamcemorus), and secondly, on account of the fact 

 that it appears as if the lake were contracting its area and 

 yielding giound to this plant and heather {Calluna vulgaris). 



On the road to the Lough we got belated Cannon ipnplia tiphon, 

 which gives a new Northumbrian locality. 



During the past summer I had the pleasure of seeing the 

 same Salda under very similar conditions in Durham. This 

 was on the shores of the reservoir on the moor at Waskerley. 

 The only other insect I noted near by was the Coccid Eriococcas 

 devoniensis distorting the Erica tetralix, which approached very 

 close to the water. 



Salda riparia, Fall. — This turned up not uncommonly with 

 Salda morio at Whitfield Lough. It was also captured in some 

 numbers around peaty pools situated on the ridge on the other 

 side of the W'est Allen. There, since the pools ran up to tbe 

 perpendicular face of the peat, the insect had different habits. 

 Normally it rested in the little inlets, but when alarmed it took 

 little journeys well iuto the pools, swimming very vigorously 

 as it did so. 



The same pools produced shoals of the caddis fly, Pltyganea 

 obsoleta, and the dragon fly, .Eschna juncea, the latter being 

 easily captured as they were drying their wings on the cotton 

 grass. 



In Durham, Salda riparia was very rare on Waldridge Fell, 

 a locality with a purel}^ sub-alpine flora and fauna, but at no 

 great elevation above sea-level. 



Gerris cosUe, H.S. — This was discovered by the Eev. J. E. 

 Hull, at Ninebanks, in a deep ravine in the mountains, the 

 occasion being marked by the discovery of the Eing Ousel nest- 

 ing. On the same day I took it in a very f-imilar ravine on 

 Great Ayton Moor in Cleveland, and at the same time I likewise 

 found the nest of the King Ousel for the first time.
