The Pupa. 



Pupation. — The caterpillars do not stop feeding until 

 some time in May or June if there be still food. After this 

 feeding period and before pupation the caterpillar undergoes 

 a moult, which is different from the others in that during the 

 time between this moult and pupation no feeding takes place, 

 and the larva remains pale-coloured, the same as was observed 

 in the case of the Wattle Bagworm. This stage is short, 

 probably only a week or two (no actual data are available), 

 after which pupation takes place. Here no inner bag or 

 cocoon is made such as we saw in the Wattle Bagworm, the 

 cavity between the pupa and the case being merely filled up 

 with soft, fluffy white silk, while an extra layer is added to 

 the inside of the covering. The bag is not fastened by means 

 of a band around the twig or stem, but it is merely broadly 

 attached to its under side, so that no damage to the food- 

 plant is caused, such as the girdling we saw resulting from 

 the attachment of the Wattle Bagworm. 



Pupation takes place during June and July, the length of 

 the pupa stage being probably about two months, as the 

 moths have been noticed from August 25th until the end of 

 September. 



Male Pupa. — Length of pupa 15 mm., width 4 mm. at 

 place of greatest width across insertion of front wings. 

 Greneral form slender, thoracic part only slightly wider and 

 deeper than the abdomen ; the last three segments of the 

 abdomen slightly curved ventrally. Posterior edges of 

 abdominal segments 4 to 7 prominent, wider than their 

 anterior edges, giving the pupa a telescoped appearance. 

 General impression of sculpture smooth, sub-shining, with the 

 dorsal part of the prothorax rugose. Colour dark reddish- 

 brown; prothorax, dorsal aspect of abdominal segments 1 

 to 4 and antennal cases darker than the remainder of the- 

 pupa, while the head is distinctly lighter in colour.
