Several interesting species are described in the following 
pages. Amongst these may be mentioned the remarkable 
species referred to as Bothnomyrmex wilsoni n. sp. which appears 
to be a parasitic form. Although described as a worker it is 
probable that this is really a female. Three examples were 
obtained in a nest of Crematogaster laeviceps Smith. This is 
the second Australian species of the genus to be taken actually 
in nests of other ants. Females of Bothriomyrmex scissor 
Crawley were found in nests of Iridomyrmex innocens For el, 
but all the examples taken are well developed winged females 
with normal gaster. 
The genus Myrmecorhynchus , until now represented by a 
single species, appears to be well represented in Australia. In 
addition to the previously unknown male and female other four 
species have been added to the genus. The habits of this group 
are not fully known ; the typical form M. emeryi Andre is 
generally found under stones or logs ; M. nitidus n. sp. has 
been taken in trees, seventy feet from the ground. 
The genera Ectomomyrmex and Lordomyrma are each repre- 
sented in Australia by one species, a second is here included in 
each. The remaining species belong to genera which are well 
represented in Australia. 
Thanks are due to the authorities of the British Museum,
