TEKMITKS FROINI THE AU8TRAUAN REGIOX. 
A very closely allied species, or possibly a small form of M. 
distinctus, is represented in my collection by two colonies of workers 
and soldiers from Hovea, 8outh-west Anstralia and Jigalono’, North- 
west Australia (collected by Mr. J. ('lark and Mr. -I. Hickmer 
respectively). The measurements of the soldiers are ; J.iength of 
head with mandibles 2'39; without mandibles 1'48; width of 
head O' 91. In size they are intermediate between typical examples 
of d/. distinctus and M. v,emnani and in gross a|)pearance closely 
resemble the latter in having long narrow heads and short stout 
mandibles ; they differ, however, as follows : In having larger 
heads, stouter mandibles, more rounded labrum (the latter with 
two long setae at its apex), different arrangement of setae on clypeus 
longer jointed antennae, pronotum with anterior margin only faintly 
emarginate and with many more setae.

Imago. 
Colour. -Head and pronotum chestnut, abdominal tergites 
auburn, postclypeus and base of mandibles lighter than head 
(Sudan brown)*; anteclypeus hyaline; labrum, palpi, antennae, 
legs and wing-stumps same colour as postclypeus ; wings light 
brown. 
Head (Fig- 67). -Very setaceous, some of the hairs noticeably 
longer than the majority ; hemispherical behind the eyes, not 
noticeably flattened on summit, ('lypeus large, markedly convex, 
rounded behind, truncate in front, with scanty setae ; anteclypeus 
very lomp nearly as long as jaistclypeus, wide at its base but narrowed 
shaT])ly to the pointed apex. Labrum large, about as long as wide, 
narrowed at the base, round on the sides and in front, widest across 
the middle, with a few moderately long reddish setae, the sides and 
apex hyaline. Antennae 14-jointed ; 3rd joint smallest ; 4th as 
long but wider than 2nd, rounded ; 5th smaller than 4th. Ocelli 
moderately large, broadly oval, well separated from the eyes (by a 
space less thaii their short diameter). Eyes circular, moderately 
large (O' 187 diameter) and prominent, finely facetted, separated 
from the lower margin of head by a space equal to that separating 
the ocelli from the eyes. 
Thorax (Fig. 68).— Pronotum very setaceous, narrower than head, 
anterior margin sinuate and slightly bent up in front, anterolateral
