20 AUSTRALASIAN ANTARCTIC EXPEDITION. 
In Text-fig. 12, I also show the head and extremity of the abdomen of the larva. 
The larve in the Collection range from about 2-5 mm. to 4 mm. in length, the latter 
being probably full grown or nearly so. They are long, rather slender, sub-cylindrical in 
shape, with each abdominal segment distinctly wider distally than basally. Their

(a) Head of a cleared specimen; a, Antenna. Jbp, Labial palpi. md, Mandible. mx, Maxilla. mrp, Maxillary palpus 
(x 874). (6) End of abdomen, showing anal papilla and appendages of seg. 9. (Xx 464.) 
general colour is of a pale, rather dirty, yellow.. The legs are rather short, the anal 
papilla or sucker and the paired appendages of seg. 9 (the so-called cerci) rather long 
and conspicuous. The antenne have the middle joint bifid distally. The mandibles, 
though strongly formed, carry no internal teeth. | Both maxillary and labial palpi are 
two-jointed, the basal joints of the former being very long. 
Larval Type on Slide No. AAE. 15, with two paratypes. The type is indicated 
by an arrow. 
Habitat.—Macquarie Island.

The Lepidoptera are represented in the Collection by a single well-grown cater- 
pillar, in good condition, preserved in 70 per cent. alcohol. As this is the first record of 
the occurrence of a moth on Macquarie Island, it seemed worth while studying the 
caterpillar carefully, with a view to placing it as nearly as possible in its correct systematic 
position,
