chamberlin: myriopoda of the Australian region. 209 



Anal tergite rounded, shorter than valves. Mesal region of valves strongly 

 compressed and elevated, roughened with irregular imi)re.s.sed lines. 



The tongue of anterior median plate of gonopods of the usual sublanceolate 

 form; the main plate with anterior margin nearly transverse, a little convex, 

 with distolateral corners rounded. The telopodite long, the outer terminal 

 branch curving mesad and then proximad. 



Coxae of the third to seventh legs in male with the usual subconical ventral 

 processes of which those of the third segment are largest. 



Number of segments, forty-eight. 



Length, to 60 mm.; width, to 5 mm. 



595. Dinematocricus eurhabdus, sp. nov. 



Ti-PE.— M. C. Z. 4,932. Paratypes.— M. C. Z. 4,933. Solo- 

 mons: Aiiki (W. M. IMann). 



Sulcus of head complete. Foveolae 2 + 2. Antennae reaching fourth 

 segment or nearly so. 



Second tergite extending well below level of coUum, flattened beneath. 

 CoUum of usual form. 



In the ordinary somites the suture curves strongly about the caudal border 

 of the pore; it is well marked laterally below and for some distance above pore 

 but is weak or obscure across middorsal region. Metazonite rising above 

 level of prozonite. Oblique striae of prozonites occurring well up toward pore, 

 the striae of metazonites ceasing near middle of side. Scobina moderate, 

 extending to thirty fourth somite. Caudal edge of somites bisinuate over 

 scobina. 



Anal valves a little compressed, exceeding the last tergite. 



Tongue of median plate of anterior gonopods lanceolate with apical region 

 long and acuminate. Telopodite with inner branch very short, closelj- ap- 

 plied to principal branch, the outer branch very long and commonly curving 

 across the opposite one in middle Une. 



Number of segments, forty-one to forty-three. 



Length of male tynpe, 34 mm. ; width, 3.5 mm. Largest female .54 mm. long, 

 with width 5.5 mm. 



At once distinguishable from the preceding species in having a nar- 

 row middorsal longitudinal blackish stripe set off on each side by a 

 still narrower fulvous stripe. The region between the middle of sides 

 and the dorsal light stripe blackish like the middorsal stripe, the lower 

 part of sides and the venter fulvous. Anal tergite mostly black 

 dorsally, fulvous pro.ximally and below; valves fulvous. Legs ful- 

 vous.
