THE INSECTS OF MACQUARIE ISLAND—TILLYARD—BRUES—LEA. 25 
was visible by transmitted light. The ventral prolegs on the abdominal segments 
are fairly prominent, and each pair is strongly armed with stout, thorn-like spines, as 
shown in Text-fig. 19. The colour of the larva is a.uniform dark-brown. 
Text-fig. 20 shows a profile view of the pupa, which appears to be of the usual 
Tipulid form, without any striking peculiarities. The specimens range from 10 to 12 
mm. in length. The colouration of the head and wing-sheaths is a very dark-brown, 
of the thorax a medium brown, and of the abdomen a light yellowish-brown.

This larva and pup may very probably belong to the genus Dicranomyia, or 
to some closely allied genus. A species of this genus has been described from Auckland 
Island by Lamb (8). 
The specimens are deposited in the Australian Museum, Sydney, in the tubes in 
which they were originally placed by the Collector. 
Family : PsycHopID&. - 
Genus : PsyCHODA. 
(‘Text-fig. 21.) 
Two specimens of a species of this well known genus were found in rather poor 
condition inside tube No... 24. As they had not been noticed by the Collector, who 
mentioned only the presence of Collembola inside this tube, I think it is very unlikely 
that they belong to the fauna of the Island. They probably became introduced into
