DIANTMCIA BAWRETTII. 11 



pupa on September 17th; the moth, a male, emerged 

 on the evening of June 27th, 1879. 



The egg in shape is round, somewhat flattened, 

 and with a slight depression beneath, the surface very 

 finely ribbed and reticulated ; the colour very pale 

 greenish-buff, and on July 6th, when first in my posses- 

 sion, showed a faintly darker speck at the top, and 

 by the 9th of the month the embryo was seen through 

 the shell as a dark spot on one side, and this next day 

 was increased in size and in depth, of a leaden hue, while 

 the rest of the shell was tinged with brownish-grey, 

 when the hatching soon began. 



The young larva at first is of a very pale rather 

 greenish-drab colour, with blackish head and narrow 

 blackish plate on the second segment. After the first 

 moult, when the larva has fairly become an internal 

 feeder, its head is shining reddish-brown, and the 

 narrow shining plate on the second segment is of similar 

 colour but a little paler, the rest of the body tinged 

 with livid reddish-grey, the skin rather shining and 

 semi-transparent, through which a dark internal vessel 

 is visible, the anterior legs reddish-brown. 



The full-fed larva measures about one inch and a 

 quarter in length, stoutest at the third and fourth 

 segments, the second tapering a little to the smaller 

 and rather narrow head, with lobes deeply defined at 

 back of the crown, tapering also from the tenth to the 

 anal extremity; the ventral and anal legs short, and well 

 beneath the body ; the segments very lightly and finely 

 wrinkled towards the well-cut divisions on the back, 

 the sides much dimpled. The colour of the head is red- 

 dish-fawn and shining, the lobes outlined on the face 

 with blackish-brown, defining well the triangular divi- 

 sion and the upper lip, and below this the mouth itself. 

 The body is of a light fawn inclining to flesh colour ; 

 a narrow scale-like plate, of glossy pale yellowish -fawn 

 colour, is on the second segment, with an interval of 

 the paler skin towards the head ; a similar plate is on 

 the anal flap, and a dorsal vessel of brownish-grey
