The Pupa. 



Colour at first almost transparent crystal white, later assuming a light 

 yellow. The eves are the first to change colour, changing to a reddish - 

 brown ; a couple of days or so before emerging the pupa becomes black, 

 excepting those portions that are white in the imago, and the markings 

 on the wings are very plain. The pupa is roughly cylindrical in shape, 

 slightly flattened dorsally and ventrally ; the greatest width is opposite 

 the end of the 1st legs ; from here the sides converge slightly towards the 

 head, which is broad and well rounded, and somewhat more so towards 

 the last abdominal segments. In profile the dorsal outline is practically 

 straight, head well rounded ; between the head and the mesothorax there 

 is a deep incision, at the bottom of which is situated the prothorax.

Figs. 4-6. — The pupa (ventral, dorsal, and lateral views). 



Ventrally there is a depression opposite the bottom of the eyes, and from 

 here the maxillae and 1st legs and other ventral appendages form a rounded 

 prominence, interrupted by the termination of the 1st legs, from whence 

 the outline gradually follows the antennae towards the anal segments. 



Such is the rough outline of the pupa. On top of the head, situated 

 anteriorly, is a small dark prominence used in pushing open the cocoon 

 on the day of emergence. The eyes are fairly large and prominent. The 

 mandibles are present, and occupy two-thirds of the oirter edge of the 

 labrum between the eyes ; between these, and occupying the remaining 

 margin of the labrum, are the labial palpi ; these are well developed, 

 and, though at first slightly constricted, widen out considerably at about 

 half their length, and then gradually taper off. On either side of these, 

 their base resting against the ' mandibles and a small portion of the eye, 

 are the maxillae ; these are very narrow, and are prolonged beyond the 

 labial palpi a short distance. On either side, beneath and somewhat 

 behind the eyes, are the maxillary palpi, forming a sort of eye-collar. Of
