THE INSECTS OF MACQUARIE ISLAND—TILLYARD—BRUES—LEA. 13 
Ventral tube fairly prominent, 0-4 mm. long when fully extended, usually 
appearing cylindrical; in the type specimen, an exserted bifid tip is visible. 
Colouration, a pale semi-transparent yellowish brown, with patches of 
darker markings. These markings are either dark-brown or blackish, except on the 
legs, where they appear touched with bluish or purplish. On the head, besides the 
black eye-patches, there is a slightly darker mid-dorsal band; in the adult, the antenne 
aodark brown. On the thorax, there is an irregular, dark, longitudinal, mid-dorsal 
band, and separate latero-ventral blotches on both meso- and meta-thorax. The legs 
are darkened on the trochanters, the tips of the femora, the whole of the middle tibio- 
tarsus, and the distal half or more of the fore and hind tibio-tarsi. On the abdomen, 
the first three segments have a dark mid-dorsal band, extending obliquely and sharply 
downwards and backwards along the sides of seg. 3, bordering seg. 4. On the 
posterior half of seg. 4, are two parallel but irregular dorsal bands, extending laterally 
downwards and backwards on either side, bordering seg. 5. ‘There is also a dark patch 
anally. 
T y pes :—Holotype, indicated by arrow, and paratype on slide No. AAK. I2, 
deposited in the Australian Museum, Sydney. A third specimen on slide No. AAE. 
18, with paratypes of Arrhopalites davidi n.sp. Also two specimens, not mounted, 
placed in 70 per cent. alcohol, in Tube No. C. 24, with the original collector’s labels 
“(C, 24,” and “Macquarie Island.” All these deposited in the Australian Museum, 
Sydney. 
Habitat:—Macquarie Island; collected by H. Hamilton. Collector’s note :— 
“Common under stones in Victoria Penguin Rookery. Garden Bay, Macquarie 
Island. 20.8.12.” 
This species is dedicated to Sir Douglas Mawson, Leader of the Australian 
Antartic Expedition. It appears to be fairly closely allied to #. pulchra Schatt, from 
Tierra del Fuego. (10.) 
Sub-order: SYMPHYPLEONA. 
Family: SMINTHURIDA. 
Genus: ARRHOPALITES, Borner. 
The Collection contains a number of mature and immature specimens of a small 
purplish-black Sminthurid, which appears to fit into this genus, on the following 
characters :— 
Ventral tube smooth-walled, without any tubercles. (Sub-family Sminthuridine). 
No clubbed hairs on the distal end of the tibio-tarsus. fourth joint of antenn strongly 
annulated. Dorsal edges of mucro similar in shape. 
The only other genera of Sminthuride recorded from the Sub-antarctic regions 
are Sminthurinus Borner and Sminthurus Latr. The former is at once distinguished
