K( < I oJ 1 1 "iid segment belom the keel- of contiguous Bomifc K- - 1 

 in general narrow, but little raised from surface, high on ide , in no 



case witli posterior angle-, at all produced. Pores <»n segments li 

 seven, nine, ten, twelve, thirteen, and fifteen to nineteen; on dorsal 

 surface. Segments strongly constricted or tun-owed between meta- 



zonite and prozonite, the latter in front of the furrow nearly as ele- 

 vated as the iiietazonite. Metazonites each with a transverse sulcus 

 caudad of which divided by finer sulci into large areas while on each 

 side the tergite is divided into numerous small slightly raised sub- 

 tubercular areas. Anal scutum triangularly narrowed caudad. Anal 

 valves margined. 



Small nodular elevations above bases of legs. In the male the first 

 legs much reduced; the second ones larger hut obviously much more 

 slender than those succeeding. Tarsi of legs very long. 



Gonopods with telopodite not segmented; each subeylindrical, 

 excavated about base above coxa, narrowing distally into a more 

 chitinous, short, flattened unbranched portion; proximally densely 

 clothed with numerous subbacilliform bodies or stout setae; in front 

 of gonopods in genotype two peculiar flattened, oval or spoon-shaped 

 bodies, each on a slender flexible stalk. Gonopods extending caudo- 

 ventrad.

Type.— M. C. Z. 4,658. New Zealand: Wellington (W. M. 

 Wheeler). 



Dusky brown above, somewhat paler along transverse sulcus and in a median 

 stripe in front of it. On the prozonites a yellow longitudinal mark on each 

 side of the middle. Paler along back. Lower part of side with a broad but 

 more or less irregular and interrupted longitudinal yellow stripe. Legs ful- 

 vous. Antennae brown. 



Vertex of head crossed by a short fine sulcus; surface marked off into 

 numerous small areas by a network of impressed lines or sulci; these also 

 covering the face down to the labial region. Hairs very short above, becoming 

 longer below level of the antenna e. 



Collum laterally strongly rounded; distinctly margined. 



Second tergite with a low tooth projecting at anterior corner of each keel. 

 Caudolateral corners of posterior segments oblique, the median | art of tergite 

 extending farther caudad than the lateral region; posterior angles of none of 

 the keels at all produced. Of the large areas caudad of the transverse suture 

 there are mostly six or seven on each plate.
