A MONOGRAPH OF THE PILL-MILLIPEDES. 279 



margins bearing a chestnut stripe which gradually fades away laterally ; 

 the extreme inferior angles of the terga and the hinder border of the 

 anal tergite also chestnut-brown. 



Legi pale green, with coxa and apices of tarsi yellow. 



Head densely punctured below ; smooth, like the nuclial "plate, above. 

 2nd tergite smooth, punctured in front ; lamina small, its margin strong- 

 ly thickened opposite the eye ; the rest of the terga densely punctulate 

 and pubescent throughout, except for the chestnut-brown border on 

 segments 3 — 7, which is polished. 



Anal tergite very slightly saddle-shaped, its edge not sulcata, weakly 

 notched, with only the posterior half sf the inner crest developed. 

 Copulatori) feet much lil^e those of A. Ilendersoni, but with the tooth of 

 the basal segment of the movable digit of the first pair shorter, and the 

 distal segment longer ; the apical tooth farther from the extremity. 



Length, 38 mm. ; width 21. 



Locality. — Salem, Sheveroy Hills {J. R. Henderson). 



Arthrosphara JDavisoni (Pocock). (PI. A, figs. 7-7b.) 



Ann. Mag. Nat. Hist. (6), XYI, p. 412 (1895). 



Colour brown or olivaceous, sometimes mottled with large pale 

 patches, the posterior portion of the tergites a little darker than the 

 anterior ; antennae olivaceous with yellow apical sensory area ; legs pale 

 olivaceous, with brightish yellow basal segments. 



Head and vuchal-plate-polished, the former coarsely and closely 

 punctured below ; 2nd tergite finely coriaceous, with distinct punctua- 

 tion along the anterior and posterior borders ; lamina small, its margin 

 strongly and abruptly thickened opposite the eye ; the rest of the terga 

 lightly wrinkled in front, finely coriaceous ; the middle of the upper sur- 

 face densely punctured in the middle, less densely in front and behind ; 

 some of the segments, i.e., the posterior, pubescent in front. 



Anal tergite only very slightly saddle-shaped, densely punctured 

 throughout ; the border not sulcate and distinctly or indistinctly notched ; 

 the inferior lateral angle marked externally with a distinct pit ; the 

 posterior half of the inferior lateral crest very small or absent, the 

 anterior half as long as that upon the preceding tergite. 



Generative organs much like those of A. Eendersoni ; the proximal 

 portion of the vulva smaller as compared with the distal portions, with 

 its angles sharper.
