other a live male pupa (text-fig. 16, e, p). The pupae are 

 Psychid in character, and since the bags are similar and the 

 locality is not far from that of the type, it is at present 

 assumed that the pupae are those of subhyalina. 



The bag sent by Janse was 8 mm. long ; the larva contained 

 therein had died while in the act of moulting, so that it was 

 not fully grown. The full-grown bags collected at Durban 

 were 10 mm. (male) and 12 mm. (female) in length, and 

 accordingly in size also these bags resembled the Grahams- 

 town bag. 



The Larva. — The caterpillar contMined in the bag from 

 Gramhamstown was dead and considerably shrunken, and 

 therefore its normal length could not be determined. It is 

 of the usual bagworm type, with radiating pattern on the 

 head and large chitinised plates on the thoracic segments. 

 The colour patterns, especially those on the thoracic segments, 

 are not sharply defined as in the other Psychid larvae, and 

 here consist more of blurred pigmented areas, a condition 

 also found on the vertex of the head, while the pattern on 

 the remainder of the parietals is fairly clear and distinct 

 <text-fig. 16, A, B, c). 



The number of hooklets on the abdominal prolegs fluctuated 

 in the specimens examined between 19 and 25; while the 

 anal claspers were armed with 18 and 19 hooklets. The 

 arrangement of these hooks was, as usual, in a single, 

 transverse loop open at its medio-caudal aspect, but those on 

 the caudal half of the loop appeared to be very much reduced 

 and becoming rudimentary. 



The bag of the mature larva is only about 10 mm. long in 

 the male and about 12 mm. in the female; it is pyramidal and 

 four-sided in shape, the sides being formed by rather neatly 

 arranged transverse sticks, composed of the small twigs and 

 midribs of the leaves of the food-plant. These are very 

 much smaller at the lower end, rapidly increasing towards 

 the mouth end. The sticks are rather thick as compared 

 with the size of the bag. With approaching pupation the 

 larva does not make an inner bag, but fills the cavity between
