Hah. — New South Wales: Sydney. Victoria: Sea Lake, 

 with Ectatomma metaUiciim. 



Uropoda obliquifrons, n. sp. 

 PL xxix., figs. 39 and 40. 



Body only a little longer than broad and only slightly 

 pointed in front. A submarginal row of simple hairs, and 

 above an inner row of long scale-like hairs, and others on the 

 middle area of the dorsum. The labial plate with its anterior 

 edge retreating obliquely each side and slightly toothed, rather 

 more in the male than in the female. Legs short, tarsi hairy 

 at tip; femur 1 of male with a spur near base bearing a 

 hair, femur 2 of male with a long spur near base, tarsus 4 

 of male with a tootli on inner edge near the middle. In 

 female only short spurs on the anterior femora. The male 

 genital aperture is between and fully its diameter from the 

 coxae 3, and there are bristles in front of it and at bases of 

 the coxae, and a few on the ventral plate. This male aperture 

 is a little nearer the posterior than anterior edge of the body. 

 In the female the genital aperture is about one-half the 

 width of a coxa behind the camerostome, and its hind border 

 is between coxae 4 and nearly truncate, the aperture is 

 broadest near its middle ; there are two pairs of bristles in 

 front of it. The peritreme makes a prominent bend outside 

 of coxae 2. Length, 1'05 mm. 



Hah. — Tasmania: Burnie, with Amhlyoyone australis. 



Uropoda submarginata, n. sp. 

 PI. xxx., fig. 51. 

 Very similar to U. apicat'a, but the plate in front of 

 coxae 1 is broader in front and the inner pointed part is more 

 triangular; there is no internal line on the venter, and the 

 dorsum has scattered hyaline dots, each with minute hair, 

 and a submarginal line of these hyaline dots, slightly elevated, 

 all around body above. Body about one and one-third times as 

 long as broad, broadest in middle, broadly rounded at each 

 end ; female genital aperture about in middle of body, one and 

 one-fourth times as long as broad, hardly narrowed and trun- 

 cate behind, where it reaches to middle of hind coxae; anus 

 about one and one-half times its length from submarginal line, 

 a bristle each side and a little behind it, but few other bristles 

 on venter ; four bristles in front of genital opening and several 

 each side. Male aperture circular, about its diameter from 

 the camerostome and from coxae 2, situated between hind 

 parts of coxae 2. Length, '6 mm.
