140 LF.PIDOPTERA. 



more reddish iu tlie luiddle ; first line placed less oblicjuely 

 and the loops or angles formed of black dusting ; second line 

 much nearer the middle of the wing, arranged in numerous 

 sharp black points, edged outwardly with pale brown ; discal 

 spot round, black ; before it is a minute black dot. Hind 

 wings rather painted, shining smoky brown ; darker toward 

 the apex and hind margin ; cilia smoky white. The male 

 when freshly emerged is usually much more olive-green from 

 the middle of the fore wings outwards, but rapidly changes 

 or fades to the purple tinge. The female similarly is 

 greenish-brown before the first line and beyond the second, 

 or even throughout, but this colour rapidly gives place to 

 reddish-brown and thence to the ordinary colour, these 

 changes taking place during life. If specimens of either 

 sex are killed very soon after emergence, and kept dry, the 

 fading is much less rapid. 



Underside of the fore wings of the male pale smoky drab, 

 with a black costal spot toward the apex and black clouds 

 near the hind margin. Hind wings smoky white with the 

 commencement of a black transverse band near the apex. 

 Female rather similar but more blackened. 



On the wing from June till August. 



Lakva moderately stout, rather broad, and even in 

 breadth from the second to the twelfth segment, the head 

 and anal segment a little narrower ; divisions and cross- 

 wrinkles of the segments all dee^j and distinct. Head full 

 and rounded, bright light chestnut, the mouth rather darker ; 

 dorsal plate reddish horn-colour, and very broad ; body 

 honey-yellow, the dorsal region faintly clouded with smoke 

 colour, which is deeper in the divisions ; dorsal line only 

 indicated as a very faint slender line on the anterior seg- 

 ments ; anal plate small, pale horn-colour, no perceptible 

 raised dots, but on each body-segment are two pairs of 

 minute brown dots having a rather sunken appearance ; 

 undersurface, legs and prolegs dull yellow, the circlets of the
