lobed, with two sensory pores on each side 
between the lateral and median lobes, and 
one large and two smaller setae on each side 
at mid-length of the lateral lobe. The epi- 
pharynx (Fig. Ic) has a group of sensory 
pores on each side with scattered setae an- 
terior to these. The clypeus or post-labrum 
has two sensory pores on each side. The 
mandibles (Fig. id) are present and, to the 
extent that the ginglymus and condyle are 
present, could be described as functional. 
They are reduced to a lobe or finger-like form 
and bear on the external face an obsolete but 
quite distinct tooth, with a large sensory pore 
basad of this and three smaller pores distad. 
There is a finely setose or spinulose area at 
the apex. The labium (Fig. 1^) has a trans- 
verse mental plate. The labial palpi are 4- 
segmented, the second segment slightly 
longer than the first, the third twice as long 
as the second, and the fourth slightly longer 
than the third with a sensory groove extend- 
ing back to mid-length. There is no finger- 
like sensory process arising from the first 
segment of the palp. The hypopharynx is 
similar to that of Agathiphaga queenslandensis 
(Fig. Hb). The maxillary cardo and stipes 
(Fig. 2) are not clearly separated. The stipes 
bears mesally a sclerotized lacinia with a 
single dorsal seta; laterad of this is the thin 
leaf-like galea which is as long as the first 
joint of the maxillary palp. The maxillary 
palps are long, folded, and 5-segmented with 
the first, third, and fourth segments sub-equal 
in length, the second shorter, and the fifth 
small and sub-globose. The pattern on the 
forewing is shown in Figure 3^ and the vena- 
tion of both wings in Figures 5b, c. The un- 
broken lines represent veins in which the
