pupal case: (Fig. 6). Length 1.1 mm., 
width 1.0 mm. Colour golden yellow, pale 
brown in median area. Shape subcircular. 
Margin (Fig. Id) irregularly toothed, about 
10 teeth in 0.10 mm. The teeth do not appear 
to constitute the actual margin which is clear 
and straight. Thoracic tracheal fold (Fig. lb) 
distinct, pore abruptly invaginated and with 
comb of 3-6 teeth. Abdominal tracheal pore 
(Fig. 1c) similar. Setae: posterior marginal, 
caudal and 8th abdominal setae present. Sub- 
marginal area 0.045 mm. wide with numerous 
large pores and separated by a line mesad of 
the pores from the dorsal disc. Similar pores 
are present on the anterior cephalic area of the 
disc before the cephalic ridge and a few on 
either side of the caudal furrow. On the disc 
are four radiating rows of similar pores, two 
immediately above the thoracic tracheal folds 
and two on the abdomen just caudad of the 
transverse moulting suture. The location of 
the smaller simple pores is shown in the fig- 
ure. On the cephalic region are two para- 
median transverse ridges on each of which 
are three or four simple pores. Above the
