later (PI. B. fig. 8.). They were laid on November 17th, 1907, 

 hatching on the 24th November ; whilst actually emerging, the 

 nymphs lack any black markings on the thorax, land those on the 

 abdomen are pale fuscous ; the eyes are dark red (fig. 1). In about 

 two hours and a half, the markings appear as in fig. 2. The young- 

 nymphs usually cluster in a ring round the empty shells, all the heads 

 inwards. There are 5 nymphal instars, the first moult occurring about 

 five days after hatching ; the second in about another 10 days, the 

 third in about 30 days, and the fourth about thirty. In the dry season, 

 the nymphal stages must last altogether over three months ; probably 

 a month or less in the wet. In the younger instars the abdomen is 

 very convex dorsally, the underside flat and wholly black. 



a is rare to find a shrub of Pavetta indica without this bug, and 

 the leaves are conspicuously marked with the white punctures left by 

 their setse. The bugs suck both leaves and berries of the plant.
