 rarely seen at large ; it keeps near the ground during the 

 day, hiding in the angles of bark, where it is not readily 

 seen, and deposits its eggs in the chinks of the bark. 



More especially attached to woods, and country districts 

 where trees are plentiful, but also to be found in the out- 

 skirts of towns and generally among trees and even bushes ; 

 moderately common throughout England and South Wales, 

 probably the northern portion also. In Scotland in the 

 South and throughout the Eastern and Midland districts to 

 Aberdeenshire and Perthshire ; but apparently in the West 

 hardly extending beyond the Clyde valley. In Ireland it has 

 been met with in the County of Dublin, in King's County, 

 Westmeath, Galway, Sligo, Fermanagh, Armagh, Antrim and 

 Derry. Abroad it ranges through Central Europe, Southern 

 and Western France, Northern Italy, Sweden, Livonia, and 

 the Ural Mountain district.
