BOARMID^-ENNOMOS. 63 



The shape of the second line of the fore wings is not 

 always reliable ; in occasional specimens it is bent inwards 

 a little, m the middle. There is considerable variation in 

 the extent of fuscous or grey-brown shading, which occa- 

 sionally does not fill the hind-marginal space quite to the 

 dorsal margin, more frequently extends itself either alone 

 the dorsal margin or the costa, and invades the paler area" 

 Mr K. Adkm has a specimen in which it extends over the 

 whole of the fore wings; while Mr. Sydney Webb has a 

 bright, light-coloured male in which it is absent from the 

 usual hmder area, or only suggested by a faint pale purplish- 

 brown shade ; in this specimen the hind wings are of an 

 unusually rich colour-almost chestnut-towards the hind 

 margin. 



On the wing in August and September. 



Larva elongate, twig-like, tapering toward the head 

 which IS small and flattened ; third segment swollen laterally ' 

 sixth and seventh segments each with a small lateral pro- 

 tuberance ; sixth and ninth provided with small transverse 

 dorsal humps ; two ventral warts also upon the seventh seg- 

 ment, and upon the anal two minute and separate points • 

 sides puckered ; colour pale brownish-green; humps and 

 protuberances tipped with dark reddish-brown • spiracular 

 stripe Ill-defined, pale yellow ; head pale green ; 'legs brown. 

 Or-Elongate, attenuated in front; no lateral or dorsal 

 humps, or protuberances, except the two ventral warts on 

 the seventh segment and the two anal points-sometimes 

 even devoid of the ventral warts-colour pea-green, sides 

 darker; spiracular stripe broad, yellow, but ill-defined- 

 ventral warts, when present, tipped with ochreous and 

 shaded with red-brown; head pale green; legs reddish- 

 brown ; prolegs tinged with dull purple. (C Fenn ) 



Another variety, reared by the late Rev. John Hellins, and 

 figured by Mr. Buckler, was reddish-grey, slightly mottled 

 with green ; spiracular stripe rather greener than the ground
