4.^2 Mr. W. C. Crawley on 



Sculpture similar to that of the type; the rujjjc 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. C. coll. 



I have not seen a specimen of michaelseni, but have made 

 the comparison with Ford'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, antennae 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 pilosida. 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 pilosida. 



Tlun'ax similar to that of pilosida, but the mesonotum 

 shorter and broader proportionately. Epinotum in profile 

 rather more convex than in pilosida. First node from above 

 as broad as long, broader than in pilosula ; iu profile it is 

 higher behind. Second node once and a half as broad as 

 the first. 



^landibles 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 tides, 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 retjculate ground- 

 sculpture on the whole body.
