chamberlin: myriopoda of the Australian region. Ill 



level of pleural surface, set oflf from above by a deep sulcus in the 

 genotype; second keels below level of adjacent ones; keels from fifth 

 caudatl much thicker or more swollen than the anterior ones. 

 Genotype. — N. scotius, sp. nov. 



306. Notodesmus scotius, sp. nov. 



Type.— M. C. Z. 4,646. Paratypes.— M. C. Z. 4,647. Tas- 

 mania: ^Yedge Bay, February, 1915 (G. H. Hardy). 



Dorsum deep chocolate to black, lower pleural and the ventral regions paler, 

 ferruginous to testaceous. Antennae like dorsum, legs blackish or dark 

 brown, proximally paler. 



Vertigial sulcus deep, extending ventrad to a Uttle above the level of the 

 antennal sockets, the sulcus at bottom of a wider furrow or depression. Face 

 with numerous long straight setae, these above level of antennae fewer, along 

 sides of median sulcus. 



Fh-st tergite with each lateral end rounded, the anterior corner more widely 

 so than the posterior; above each lateral margin with a deep longitudinal 

 furrow, margined below and a httle ways up anterior side. Other tergites 

 smooth and shining, the prozonites very finely coriarious, the metazonites 

 smooth excepting in some certain obscure longitudinal rugae toward each side 

 and more particularly caudad of the transverse sulcus. Metazonites from the 

 fourth to the eighteenth inclusive with a deep transverse sulcus which ends on 

 each side well above the level of the keels. Longitudinal sulci hmiting keels 

 above deep and sharply defined. 



Anal scutum narrowed caudad in the usual manner, the cauda rather wide 

 and flattened dorsoventrally, not at all subcyhndrical, the caudal margin 

 truncate or mesally shghtly notched. Dorsal surface, especially caudad of 

 middle, obscurely transversely rugose; with two transverse series of setae 

 additional to those projecting from caudal end, one near middle and one a 

 Mttle in front of caudal border. Anal valves sharply defined mesally. Anal 

 scale caudally convexly rounded, convexly elevated between the two setigerous 

 tubercles. 



Length (female), to near 16 mm.; width, 2.5 mm. The males more slender, 

 the width of a specimen 15 mm. long being near 1.8 mm.
