LARENTID.-E—COkEMlA. 163 



smoky lines and shades; second line more distinct; bind 

 margin broadly clouded with pale purplish-brown, in which is 

 a series of black-brown dots edged with white. Hind wings 

 very similar to the upper side, but the transverse stripes 

 more complete. Body ashy-brown; legs dark brown, spotted 

 with ochreous. 



Variable in the gronud colour from pale ochreoiis-brown to 

 pale grey-brown ; still more so in the colour of the central 

 Ijaud, from black and black-brown to darker or paler purple- 

 brown or clear purple ; and in the width of this lumd. xV 

 specimen captured near Greenwich by Mr. W. West had this 

 central baud exlremely narrow, but the examples which he 

 reared from its eggs were normal, In an enormous series of 

 specimens reared continuously for several years for purposes 

 of experiment, by ilr. Louis B. Prout, a very large propor- 

 tion have the central band purple. Df these some have a 

 distinct whitish rivulet-stripe before and after the central 

 band, this rivulet-stripe being finely divided, and sharply 

 edged, with grey-black lines. Among them is a very striking 

 aberration in the opposite direction, a specimen having the 

 central band black-brown, and of only one third the usual 

 width, while the whole remaining area of the fore wings is 

 smooth pale orange buff — a very remarkable insect. 



On the wing toward the end of May and in June, and in a 

 second g-eneration in August. 



Lakva elongate, slightly attenuated iu front ; face shining, 

 bead rounded, pnle brown dusted with darker, and having a 

 broad black dash on the outside of each lobe ; black-brown 

 on the back and sides, the last four segments i)aler, often 

 ochreous ; an orange or reddish-ochreous dorsal triangle, 

 is outlined with black and often filled up with dark-brown on 

 each segment from the fifth to the ninth, the apex being in 

 front and enclosing a conspicuous black spot; ou the other seg- 

 ments is a blackish ill-defined and interrupted dorsal stripe ; 

 subdorsal lines pale ochreous, broad from the tenth to the
