400 MR. R. I. pococK ON SOME [Dec. 2, 



differs, as also it does from P. cdbipcdpis, in having the ocular 

 tubercle and the area of the carapace in front of and at the sides 

 of it much more thickly and strongly denticulated. 



Measurements in mm. : — Length of carapace 2 ; of 1st segment 

 of mandible 10, of 2nd 11. 



Log. New Zealand : West Taieri Bush, Otago {J. V. Jennings). 



One male example without its legs. 



There is also in the British Museum a female example with the 

 mandibles much shorter and thicker than in the above described 

 males, which may represent the female sex of either of the forms 

 of P. nigripalpis. It was collected in Maungatua by Mr. J. V. 

 Jennings.

 Tri^nobunus pectixatus, sp. n. (Text-fig. 84, C, p. 410.) 



Colour blackish ; legs variegated with yellow. 



Dorsal scute depressed, ornamented with a network of granular 

 ridges separated by smooth interspaces and showing a segmental 

 arrangement behind the cephalic constriction, forming four trans- 

 verse rows which pass between the five rows of tubei-cles ; of 

 these tubercles the median are the largest and recurved (text- 

 fig. 84, 0). Ocular tubercle directed upwards and forwards, long, 

 spiniform, armed above with smaller procurved spiniform tu.bercles, 

 below with one, and on each side with three long spines, the first 

 close to its base, the third with its fellow giving a tridentate 

 appearance to the tubercle ; on each side of the tubercle there are 

 five long strong spines. The first and second free tergites granular 

 and armed, like the posterior border of the scute, with seven 

 strong spines, one being median ; the ohird tergite less regularly, 

 but not less strongly spined ; the fourth (anal) tubercular. 

 Stei-na with a transverse series of tubercles. 



Mandibles weakly tubercular. Palpi shortish, not very strong, 

 shorter than the dorsal scute ; the femur with some hair-tipped 

 tubercles above and three long spines below ; tibia with two, 

 tarsus with three pairs of interior spines. 



Legs with coarsely granular coxee, that of 1st shortly spined in 

 front, of 2nd and 4th strongly spined above externally ; tro- 

 chanters and femora also spined, especially the femur of the 1st, 

 which is armed with long, stout, close-set spines, those on the 

 dorsal side forming a series, ten in number ; patellae and tibiee 

 tubercular, tubercles on the 1st leg more spiniform than those on 

 the others ; constricted portion of protarsus subconical ; tarsal 

 segments of 1st 3, of 2nd 6, of 3rd and 4th 4 ; ultimate segment 

 of 3rd and 4th tarsus longer than the antepGnultim.ate (second).
