270 LEPIDOPTERA. 



slender transverse brown line, and this by an elongated 

 black-brown costal blotch before the apex ; hind margin 

 shot with purplish-brown ; central spot of the hind wings 

 lunate, black ; beyond it is a slender curved brown transverse 

 line, followed by one or two similar cloudy spots ; hind 

 margin tinged with purple-brown. Body and leg-tufts ashy- 

 white, tibise dark brown, barred with the same. 



Not variable except a little in the depth of colour of the 

 fore wings, and the extent of dark shading on the hind. 



On the wing at the end of May and in June. 



Larva long and slender for the size of the moth ; body 

 evenly rounded above, flattened below, tapering a little at 

 the extremities ; head slightly wider than the second segment, 

 lobes rounded ; anal prolegs extended and forming a distinct 

 angle. Head of various shades of brown, in some cases of 

 a dark sienna colour ; in all there is a pale yellow triangular 

 frontal mark, and a distinct streak of yellow on the side of 

 each lobe ; ground colour some shade of ochreous-yeilow, the 

 darker specimens having a strong tinge of rust colour along 

 the sides ; dorsal stripe brown, edged outwardly with yellow, 

 and enclosing a very fine yellow line ; subdorsal stripes 

 double, smoke-coloured ; between these and the dorsal line 

 are two more irregular yellow lines ; another lies beneath 

 the subdorsal, and above the spiracles a yellow line edged on 

 each side with smoke colour ; spiracular stripe also smoke 

 colour; spiracles and raised dots black; undersurface of 

 various shades of dull ochreous, with two grey lines down 

 the middle, and a black mark on the seventh and eighth 

 segments. When very young it arches itself in walking 

 quite like a Gcomctra, and is of a semi-transparent pale 

 green barred with dark brown, or nearly black ; the hairs 

 rather long ; head pale shining brown. When half grown it 

 has lost the true looper style of walking and has become 

 a half-looper, having two pairs of ventral prolegs. The 

 ground colour now varies from pale salmon to dull pink, or
