Show 412 MR. R. I. POCOCK ON SOME [Dec. 2, forming a low rounded elevation ; second segment scarcely tubercular. Palpi (text-fig. 84, B) long and robust; femur strongly convex above, with a setiferous tubercle at the base below, and a smaller one near the middle of the inner surface; patella without tubercles; tibia convex below, one-third longer than the patella, armed beneath beyond the middle with a pair of setiferous tubercles; tarsus armed with three pairs of setiferous tubercles, the distal the smallest. Coxae of legs granular like the dorsal surface, some larger granules on the posterior border of the 2nd, 3rd, and 4th legs ; rest of the leg-segments without spines; femur of 1st tubercular beneath. Tarsal segments 3, 5, 4, 4 ; those of the 1st leg subequal, the second segment only slightly shorter; of 3rd leg the first tarsal is about as long as the second and third, the third and fourth being subequal and slightly shorter than the second; much the same proportion of segments prevails on the tarsus of the 4th leg. Measurements in mm. :-Total length 2'5 ; palp 3 ; 2nd leg 7, 4th 6. Loc. Tasmania. Specimen received from Mr. G. W. Peckham. Group L a n ia to r e s . Family H i x z u a x i ix e . Genus H ix z u a x u s (Karsch) Loman. H ix z u a x u s l e ig h i , sp. n. Colour of trunk and legs yellow, thickly clouded with black, the mandibles mostly yellow; femur and patella of palp yellow, distal segments infuscate, a pale ring round the femora and tibiae of the legs. Trunk thickly granular above and below; no spiniform processes on the fore border of the carapace. Eyes large, distance between them much greater than that between either and the fore border of the carapace. A deep groove behind the carapace; abdomen elevated, convex, its third and fourth segments with a pair of sharp submedian tubercular spines; a row of large tubercles along the posterior border of the dorsal scute and of the following three tergal plates ; the anterior four tergites subequal in length. Femur of palp with a setiferous tubercle beneath ; patella with apical spine, tibia and tarsus with two pairs of spines. Tarsus of 1st leg with three, of 2nd to 4th with five tarsal segments. Measurements in mm.:-Total length 4 ; width 2; height 2 ; 1st leg 7, 2nd 11, 3rd 8\5, 4th 12*5. Loc. S. Africa: Natal (G. F. Leigh). Distinguishable by the presence of the spiniform tubercles on the third and fourth tergites, a character suggestive of what occurs in the genus Lacurbs. Since Hinzuanus, according |
