P10NEA STEAMENTALIS. 157 



is of a dingy drab-green, less dark than the back ; the 

 anterior legs are greenish, the ventral and anal legs 

 almost colourless ; after the ten days' feeding, and 

 while still eating at intervals, it gradually contracts its 

 length, and the dark back assumes a bright purplish- 

 violet-coloured ground more shining than before, when 

 it is very beautiful; but in two more clays' time it 

 ceases to eat, and then the spiracular yellow stripes 

 lose their brilliancy, while it lingers a few hours before 

 spinning its cocoon on or just below the earth, wherein 

 it remains in the larval state and retains the purple- 

 violet colour until the spring of the year following, 

 when it changes to a pupa. 



The broad-oval cocoon is covered with particles of 

 earth, and measures from 16 to 19 mm. in length and 

 from 10 to 12 in breadth, the interior being very 

 smoothly lined with pale drab-coloured silk. 



The pupa is of rather a dumpy figure, from 8 to 9 

 mm. long, the wing-covers longish, of a light 

 yellowish-brown colour marked with dark brown, and 

 having the nervures in high relief; the e}^e-pieces and 

 abdomen dark brown, the surface smooth and glossy ; 

 the last segment of the abdomen is a little prolonged 

 and rounded off at the tip, without any points of 

 attachment, which probably would be in this instance 

 superfluous, as the tail of the pupa is brought to rest 

 closely packed against the side of the cast-off larval 

 skin, bristling with stiff hairs, which evidently afford 

 sufficient support and resistance for the escape of the 

 insect. (William Buckler, 11th September, 1882; 

 E.M.M., November, 1882, XIX, 126—130.)

On the 8th of June, 1866, Mr. T. Brown, of Cam- 

 bridge, kindly sent me eggs of this species. 



These were roundish in form, shining, and very soft
