TORTRICID.E—LEP TOGRAMMA. 2 1 5 



band, though usually not so broad or else broken into stripes, 

 one of them Y-shaped. These forms occur constantly with 

 the type, but in far less numbers. In Scotland another 

 variation is found, nearly unicolorous purplish-brown, with 

 faint shady indications of the darker markings. This variety 

 is confined to hill districts. Variation also takes place in the 

 depth of the costal excavation. 



On the wing from July till Sejitember. 



Larva verdigris-green, with raised dots of the same colour ; 

 divisions of the segments yellowish ; head pale honey-yellow ; 

 dorsal plate and feet light green. (Hofmann.) 



May and June on sallow, birch, hazel, aspen, poplar, and 

 alder, folding the leaves, drawing the shoots together, or 

 turning down the edge of a leaf. 



Pupa stout, light" brown or red-brown, wing and limb 

 covers shining : segments dull ; cremaster broad and hooked. 

 In the larval habitation, or under moss on tree trunks, or 

 spun-together fallen leaves. 



The moth is especially attached to well-grown hedges 

 where sallow is plentiful. Here it hides in the bushes by 

 day, but is easily beaten out, when it will often make a sort 

 of flat flutter like a bit of leaf falling to the ground, but also 

 is often quite active in flying away. Common in hedges and 

 woods in the south, and to be found throughout the United 

 Kingdom, though not always in plenty. Abroad it is com- 

 mon throughout Central and Northern Europe, and North 

 America. 



Genus 15. LEPTOGRAMMA. 



Antennas slender, notched ; palpi rather short but por- 

 rected ; thorax tufted at the back ; fore wings arched and 

 expanded near the base, the arch of the costa roughened 

 with erected scales, and beyond ciliated ; surface generally
