Uropoda fraterna, n. sp. 

 PI. xxx., %. 49. 



Very similar to U. internata. The plate in front of 

 coxae 1 is more acute in front, and shows an inner curved 

 ridge; the female genital aperture is nearer to the camero- 

 stome, and is about one and one-third times longer than broad ^ 

 not noticeably narrowed behind coxae, and not reaching much 

 behind middle of hind coxae. The venter shows an internal 

 line, as in U. internata, but it is farther in front of the anus: 

 there are hairs around genital aperture and on venter, as in 

 U. internata, and some between the internal and submarginal 

 lines. The male genital aperture is circular and situated 

 between coxae 2, and hardly its diameter from the camero- 

 stome ; the plate in front of the coxae 1 is more nearly 

 truncate in front. Length, *45 mm.

Uropoda internata, n. sp. 



PI. xxviii., fig. 35. 



Yellowish-brown. Body about one and one-half times as 

 long as broad, broadly rounded at each end, broadest near 

 middle ; no hairs on dorsum ; plate in front of coxae 1 roundly 

 triangular ; female genital aperture nearer to posterior than to 

 anterior end, fully one and one-half times as long as broad, 

 broadly rounded in front, narrowed at hind coxae, almost trun- 

 cate behind, where it reaches hind edge of hind coxae ; in front 

 quite widely separated from camerostome, two pairs of hairs 

 in front, four each side, and one behind hind coxae, venter 

 with some scattered fine hairs ; anus almost reaching the 

 submarginal line, in front of it a distinct internal line extend- 

 ing up each side to hind tarsi. Legs very short, especially 

 femora, tarsi with stout spines, except tarsus 1 with fine 

 hairs near tip. Length, - 4 mm. 



Hab. — Tasmania: Devonport, witli Iridornyrmex . 



Uropoda longifrons, n. sp. 

 PL xxviii., fig. 32. 

 Very similar to U. eonvexifrons from Tasmania and with 

 the same host; but the plate in front of coxae 1 is plainly 

 longer, about as long as broad. The body is about one and 

 one-third times as long as broad, broadest behind the middle, 

 narrowed in front; no hairs on dorsum. The female genital 

 aperture is much closer to the hind than to the front end, about 

 one and one-third times as long as broad, slightly narrowed 

 and truncate behind, where it reaches the hind edge of hind 

 coxae, in front well separated from the camerostome, four 

 bristles in front of it ; anus hardly its length from the sub- 

 marginal line; few, if any, hairs on venter; tarsi with short
