Sculpture similar to that of the type; the ruge on the 
head are fairly rugular and coarse, on the pro- and meso- 
notum they are regular but finer; the epinotum is exactly 
as in michaelseni; the first node is more coarsely rugose 
than the head. The rest as in michaelseni, including the 
deep golden pelisse on gaster. 
Perth (Clark, no. 65). 
Type W .'C.<Cicolk: 
I have not seen a specimen of michaelseni, but have made 
the comparison with Forel’s very complete description. 
Myrmecia CLARKI, sp. n. 
%. Length (without mandibles) 9°8-10 mm.; length of 
mandible 2°4 mm. 
Black; mandibles and tarsi dark yellow, antennz nearly 
black. 
A few hairs on mandibles, clypeus, and apex of gaster, 
the latter with a very thin grey pubescence. 
Mandibles considerably longer than head, narrow, the 
outer edge feebly concave, the point long and curved, 
followed by three large teeth with two smaller between each 
pair, the remaining half of the mandible bears a ridge of 
6-8 small teeth directed backwards. Eyes large, occupying 
more than half the sides, and almost touching the base of 
mandibles. Scape passes the occiput by about its width. 
Joint 2 of funiculus once and a half as long as first, the 
third as long as first, the remainder diminishing in length 
to the apical, which is slightly longer than the preceding. 
The whole antenna thinner than in pilosula. Head broader 
than long, slightly narrowed behind, the occipital border 
feebly concave. Clypeus incised in centre of anterior 
border, but not depressed up the centre as in pilosula. 
Thorax similar to that of pilosula, but the mesonotum 
shorter and broader proportionately, Epinotum in profile 
rather more convex than in pilosula. First node from above 
as broad as long, broader than in pilosula ; in profile it is 
higher behind. Second node once and a half as broad as 
the first. 
Mandibles with scattered small punctures, and a few 
elongated ones near the apex. Whole of head regularly 
and finely striate longitudinally. Pronotum with coarser 
regular ridges, encircling the neck and sides, longitudinal 
on top. Mesonotum and base of epinotum similarly longi- 
tudinally striate, declivity transversely striate. First node 
coarsely longitudinally rugose; second and gaster micro- 
scopically reticulate. There is a similar reticulate ground- 
sculpture on the whole body.
