372 I.f.rinOPTERA. 



The niotli liides about alder-trees in tlie daytime, usually 

 in the branches and amon<r the leaves, but occasionally sitting 

 upon tlio t'unks or on any neighbourins' railing. If beaten 

 out it flies liurrifHlIy away to a similar hiding-place. Its 

 tlight at dusk is more especially around the trees, yet also 

 about alder bushes and neighbouring hedges ; later at night 

 it will come to a strong light. From the nature of its food 

 it is necessarily confined to damp places and the margins of 

 streams, or the swam])y parts of woods, but its favourite 

 haunts are certainly the rows of alder-trees which so often 

 skirt the little streams running along the hollows of valleys. 

 In such places it seems to occur throtighout England, though 

 locally and not always commonly ; indeed, it is scarce in some 

 of the more nortliern districts. Found also in (Hamorgan- 

 shire and Pembrokeshire, and in North Wales in Flintshire. 

 In .Scotland it is found in similar sjwts in the eastern 

 districts to Moray, and in the westein to the Clyde Valley ; 

 and is certainly quite common in Stirlingshire, more in the 

 middle of the country. It is also recorded from the Hebrides, 

 and from Orkney, though most of the specimens here said 

 to belong to this species really are referable to the last. 

 Still, Mr. F. M. Cheesman sent specimens from Stromness 

 some few years ago. which belonged clearly to the present 

 species. In Ireland it is very local, yet widely distributed, 

 since it has ()een foutul in Dublin County. Wicklow. Louth. 

 Westmeath. Monaghan. Sligo. Tyrone, Fermanagh, Down, 

 .\nt rim. and ! )erry. 



Abroad its range is throughout Central and Northern 

 Europe, ^liddle and Northern Italy, the Ural Mountain dis- 

 tricts, and Fastern Siberia.
