present but the two lateral sutures are absent. 
The unsclerotized scale-bearing areas are 
similar to those of A. vitiensis. The labrum 
(Fig. ^a) is distinguished by the more nu- 
merous setae, concentrated at the sides but 
extending across the disc. The epipharynx is 
similar to that of A. vitiensis. The mandibles 
(Fig. 8c) have an obsolete tooth and their 
apices have a finely toothed or crenellated

area. The hypopharynx (Fig. 8^) has what 
appears to be an orifice at mid-length and, 
anterior to this, a broad median setose band. 
The mental plate is absent or represented by 
a very narrow transverse sclerite. The labial 
palps (Fig. ^d) are 4-segmented, the first | 
and second subequal in length, the third one- I 
half as long again and the fourth twice as 
long as the third with the sensory groove ex- i 
tending back to mid-length. The maxillae | 
(Fig. 8c) have the lacinia present and bearing 
four short setae, galea present, maxillary 
palps 5-segmented and folded. The first and { 
fourth segments are sub-equal, the second 
and third ' sub-equal and shorter than the 
first, the fifth short about one-third the length 
of the fourth, sub-conical and about three 
times as long as wide. The differences in the 
wing venation are seen in Figure 9^, h. The 
figures of the venation in this and in the pre- 
ceding species are based on the study of the 
unexpanded wing of the adult extracted from 
the pupa. I was later able to study the wings 
of naturally emerged moths of A. queens- 
landensis. In the forewing the humeral vein 
is sometimes absent or indistinct. In one 
specimen Sc has a short branch. The cross 
vein Sc-Ri is absent or indistinct. Rs is 2- 
branched in some specimens as also is M3. 
The cross veins Cu2-Cuib and IA-CU2 are 
absent. In the hind wings I am unable to 
check the veins of the anal area owing to the 
condition of the specimens, but the rest of 
the wing coincides with the figure given. The 
female genitalia (Fig. 9c) are similar to those 
of A. vitiensis. The male genitalia are essen- 
tially similar to those of A. vitiensis. The 
aedeagus is missing in the single male speci- 
men available. The principal differences are in 
the structure of the tenth tergite and tenth 
sternite (Fig. ^d). 
PUPA: The main difference between A. 
queenslandensis and A. vitiensis is in the man- 
dibles (Fig. 10a), as mentioned in the descrip- 
tions. The number of long setae on the clyp- 
eus and labrum is variable. In the pupal skin 
of the type there are only 4 setae asymmetri-
