Material Examined. — Specimens from Leptospermun sp., Australia, de- 

 termined by Froggatt at this species and agreeing in general with the original 

 description. 



Notes. — Assuming this determination to be correct (as it doubtless is) the 

 original description is in error in the statement that the anal ring is hairless. 

 Also the original description hints at the presence of abdominal spiracles, which 

 are certainly lacking. 



This species appears to differ from A. mesuce and A. acacicB in the much 

 deeper anal cleft and the form of the chitinized areas about the anal opening,. 



Genus -Kuwanina Cockerel). 

 Kuwaninaobscurata (Maskell). 

 Fig. 35. 



Habit. — Occurring in galls which are mere swellings of the bark. 



Morphological characteristics. — Adult female (Fig. 3A) apodous and with 

 the antennae reduced to mere vestiges with three or four minute segments. 

 Form broadly oval or subcircular. Derm everywhere heavily chitinized. 

 Anal opening appearing on the ventral side, small, heavily chitinized and only 

 slightly cellular, bearing six very small spines. The opening is covered by a 

 small, cauda-like fiap. Constrictions between the abdominal segments very

deep on the dorsal side and extending somewhat to the Ventral side. In these 

 constrictions there appear numerous pore- like openings which communicate 

 with invaginations of the derm (Fig. 35B). These invaginations show no evidence 

 of internal pores and are, therefore, hardly to be described as ducts. They are 

 confined to the intersegmental furrows of the abdomen and are most numerous 

 toward the posterior end, forming a continuous, transverse row on the last
