PH 1 C/TID.E—SA LEBRIA. 433 



grey freckles ; body cylindrical and nearly uniform , wrinkled 

 and velvety, dark green ; dorsal line double, slender, grey ; 

 interrupted ; subdorsal lines similar, followed by two more 

 above the spiracles, and another along them ; dorsal plate 

 smooth and rather horny and polished ; ventral surface 

 dark green, powdered with white at the segmental divisions. 

 (G. T. Porritt — condensed.) 



July to September or even October ; on elm, especially 

 frequenting elm-6«s7(e.s ; under a white web on the upper 

 side of the midrib of an elm leaf, the leaf remaining flatly 

 open and not distorted or sf)un together. In confinement 

 found also to feed on birch. 



Pupa rather slender, limb covers tolerably compact, wing 

 covers large and long, the whole of this portion tolerably 

 smooth and without noticeable sculpture, deep green ; dorsal 

 region faintly punctured, brownish-green ; segments of the 

 back and abdomen much sculptured into fine pits, each having 

 a smooth hoop at the back, light chestnut with a faint 

 green tinge ; anal segment black brown ; cremaster short 

 and squared, armed with a minute bunch of bristles. In a 

 soft silken cocoon, in the earth, or in rotten wood. 



The moth conceals itself in thick hedges of elm, and if 

 beaten out seems almost always to fall to the ground and 

 hide itself ; but flies at dusk and till rather late at night, 

 and comes readily to light, indeed it used to be a frequent 

 visitor to gas lamps in the southern suburbs of London. 

 Otherwise it is rarely captured, and the large majority of 

 specimens in cabinets have been reared from the larva state. 

 It now appears to have become rare in these suburbs, and 

 elsewhere is exceedingly local, but may be found in suitable 

 places in Kent, Surrey, Hants, Herts, Cambs, Essex, Norfolk, 

 and Suffolk. These counties seem to indicate its ransre in 

 the United Kingdom. Abroad it is found throughout 

 Central Europe, Dalmatia, Russia, Pontus, Armenia, and 

 Persia.
