chamberlin: myriopoda of the Australian region. 9 



plate overlapping the cephalic plate; without cur\e(l transverse 

 sulcus. Antennae composed of fifteen articles. Anterior margin of 

 presternum very slightly convex on each side; setae 4 + 4. Cruci- 

 form impression on sternites distinct back to the nineteenth plate, 

 the longitudinal branch about as well de\'eloped as the transverse; 

 on the twentieth and twenty first plates a weak longitudinal sulcus 

 also evident but a transverse impression indicated obscurely only on 

 the first of these. Paired dorsal sulci present from the third segment 

 caudad. Last ventral plate with sides a little convex, a little con- 

 verging caudad; caudal margin nearly straight, vaguely convex. 

 Coxopleurae caudally slightly rounded, subtruncate; the caudal 

 margin bearing a number of spiniform setae; caudal third free of pores. 

 Femur and tibia of anal legs bearing numerous slender spines ventrally 

 and on the sides but without teeth; metatarsus with a series of nine 

 or ten teeth, the first tarsal article with four. Penult legs beneath 

 with numerous fine hairs and scattered longer and stouter setae; 

 no spines or teeth. Spiracles large, longitudinally subelliptic. 

 Length, about 15 mm.

Type.— M. C. Z. 1,922. New Zealand: Wellington, 18 August 

 1914 (\V. M. Wheeler). 



Color fulvous. 



Cephalic plate with caudal margin free, overlapping the first dorsal 

 plate, a short median sulcus in frontal region and a pair of short sub- 

 median sulci in front of caudal margin. First dorsal plate without 

 either transverse or longitudinal sulci. Second tergite with paired 

 longitudinal sulci; much shorter than the first one. Last dorsal plate 

 with caudal portion triangular, the median angle narrowly rounded. 

 Prosternum with anterior margin convex on each side, edge chitinous, 

 bearing on each side three or four setae. Ventral plates not rough- 

 ened; last one caudally truncate. Coxopleurae short, caudally 

 rounded; caudal margin bearing several spinescent setae; pores few 

 (near twenty), partly covered, not reaching caudal margin. Penult 

 legs with third and fourth joints beneath with numerous spines, cor- 

 responding ones on other legs becoming fewer and more slender in 

 going cephalad. Anal legs with similar spinescent setae; metatarsus 

 armed beneath with six teeth, first tarsal with two. 



Length, 13 mm.
