chamberlin: myriopoda of the Australian region. 131 



Legs long and stout. Tliird joint of legs dorsally very (conspicuously 

 swollen or elevated except proximally. Tarsus much longer than any other 

 segment, slender, moderately curved. 



The chitinous distal region of the telopodite of gonopods is flattened from 

 side to side; and expanded like the tail of a fish, the distal edge being similarly 

 notched or excavated, curving a little dorsad; the chitinous structure is con- 

 tinued proximad as a narrow rim along the mesal side of the gonopod. Just 

 proximad of terminal narrower chitinous portion there is from the dorsal side 

 a low triangular plate projecting dorsad. 



Width, 2.8 mm. 



358. Prionopeltis dasys, sp. nov. 



Type.— M. C. Z. 4,701. Fijis: Viria, Ruva River (W. M. Mann). 



Brown or in part chocolate colored, the callum and head darker, the keels 

 all yellow and the tip of the cauda somewhat ferruginous. Venter hghter 

 brown. Legs proximally testaceous, distally flavous. Antennae dark brown. 



Head with vertigial sulcus distinct down to level of antennal sockets. 

 Surface densely granular or shagreened, in part rugose. Antennae long and 

 slender. 



Metagonites densely granular or shagreened both above and down the sides. 

 CoUum with a median longitudinal sulcus which is not evident over either 

 anterior or posterior border regions. A deep transverse sulcus present from 

 fourth to nineteenth segments, this extending across from keel to keel excepting 

 on the fourth, on which it is abbreviated and on the nineteenth on which it is 

 also short and rather indistinct. Margin of keels smooth, elevated, on the 

 edge hollowed out only about and a httle distance caudad of the pore, the 

 non-porigerous keels not hollowed out as in P. keleearti Hmnbert. 



Pleural keels evident on segments II to V; those on the second and third 

 segments rather vertical than transverse, those of the two others thicker and 

 more nearly longitudinal. Proemea near bases of legs as usual. 



Cauda of anal tergite long, subcyhndric, distaUy rounded, much exceeding 

 the valves. The latter strongly margined, coriarious. 



Length (female), near 43 mm.; width, 7 mm. 



359. Prionopeltis clarus, sp. nov. 



Type.— M. ( \ Z. 4,630, Fijis : Some Some. Paratypes.— M. C. Z.
