It is doubtful if this species is as widely distributed as is recorded 
and until imagos are available for confirmation South-west and 
North-west Australian records should be regarded as provisional 
only. Michaelsen and Hartmeyer’s specimens from Serpentine, 
Western Australia, some of which 1 have seen, are undoubtedly 
referable to L. ocoidims, while others from the same collection 
referred to L. ferox by Silvestri are doubtless L. darki. Of 88 nest 
series collected by Mr. J. Clark in South-west Australia 86 are 
referred to either L. darki or L. occiduus ; the remaining two series, 
represented by soldiers and workers only, appear to differ specifically 
from all described species. Midberg's specimens (soldiers) from 
Cedar Creek, North Queensland, do not agree with PVoggatt’s ty])e, 
nor with any other described species. 
The imagos of L. ferox have 16-jointed antennae (40 specimens 
examined) ; the 3rd joint is generally the smallest of all, but it is 
commonly larger than the 4th. The soldiers generally have antennae 
of 15 joints ; 16-jointed antennae are rare (this number occurs in a 
co-type). 
Locality. — New South Wales ; Broken Hill (P\ Shepherd) ; 
Victoria : Lakes Entrance and Mallee District (E. E. Wilson), Sea- 
ford (W. F. Hill) ; South Australia (Tepper, from South Australian 
Museum collection). 
Affinities. -This species is closely allied to L. occMuns and L. 
harretti (q.v.). 
Biology.- Most of the colonies examined by me were collected 
under stones or logs or in the walls of nests of Coptotermes ; but in 
one instance (Seaford, 4.10.20) a community comprising all castes, 
including numerous alate imagos, was found in association with 
Caloterm.es {G.) rufinotum Hill (= obscurus Hill nec Walker) in a 
soft-wood verandah- post the interior of which was considerably 
damaged by termites.

A more detailed description of this species is necessaiy to dis- 
tinguish it from others added to the list since the publication of
