The Silvery Arches {ApkcUi {Mamcstra) tinda). 



The moth represented on Plate 117, Fig. 5, has the fore wings 

 silvery grey clouded with brownish on the central area ; or 

 occasionally spreading over a larger portion of the wings, and 

 sometimes purplish in tint. The caterpillar is brownish inclining 

 to reddish, clouded on the back with paler and darker brown , 

 The central line, which has a broken blackish edging, is only 

 distinct on the front rings. Spiracles black ; head pale brown 

 marked with darker brown. In the autumn it feeds on low^ 

 plants such as dock, plantain, etc. ; but in the spring it is found 

 at night on the young growth of birch and sallow bushes, and 

 more rarely on hawthorn, and I believe, on bilberry. The 

 moth which occurs in birch woods in June and July, is not 

 uncommon in the south of England from Essex to Hampshire, 

 and has been found in Dorset and Devonshire. It has also 

 been obtained more or less frequently in Berkshire, Oxfordshire, 

 Cambridgeshire (once), Huntingdon, Worcestershire (Wyre 

 Forest and Malvern), Staffordshire (north), Lancashire (Wither- 

 slack), Yorkshire (Huddersfield, once), and Westmoreland. In 

 Scotland it ranges on the west from Ayr to Argyllshire, but 

 although local is more frequent in Perthshire, Moray, and 

 Sutherland. Var. obscurata^ Stand., is a form of this species 

 occurring in Amurland and Southern Siberia.
