cally arranged on the clypeus and 10 symmet- 
rically arranged setae on the labrum. Another 
specimen has 6 setae on the clypeus and 10 
on the labrum. 
LARVA: The larva is very similar to that of 
A. vitiensis except in its smaller size. The 
main point of difference is in the shape of the 
lateral extensions of the posterior foramen 
(Fig. 10^) which are not triangular but ovoid 
owing to the constriction produced by dorsal 
and ventral processes from the epicranium. 
The only other difference is in the labral setae 
(Fig. 10c). On each side, at the anterior mar- 
gin, two setae project anteriorly, while be- 
neath these are two others instead of the 
single seta present in A. vitiensis. The man- 
dible is shown in Figure 10^. 
SYSTEMATIC POSITION 
The Micropterygidae are characterised by 
the possession of functional toothed man- 
dibles, a maxillary lacinia, and an unspecialised

galea. One pupa, that of Sabatinca incon- 
gruella Walk., has been described by Tillyard 
(1923^: 445-448). It has a triangular man- 
dible. The larvae of Micropteryx calthella L. 
and M. aureatella Scop, have been described 
by Chapman (1894: 341-344; I916: 313) and 
that of Sabatinca barbarica Philp. by Tillyard 
(1923^: 440-445). These three larvae have 
long antennae, compound eyes (at least in 
Sabatinca)^ thoracic legs, abdominal prolegs, 
and flattened body processes. They are ex- 
ternal feeders on mosses and liverworts. The 
family is represented in most regions of the 
world except the oceanic islands of the 
Pacific, the Australian and New Zealand rep- 
resentatives belonging to the genus Sabatinca.
