(Pocock, 1895, Ann. Mag. Nat. Hist. (6), xvi., p. 414.) 



This genus was ci-eated by R. 1. Pocock with the New 

 Zealand Splin'rutlu'ri nm innjiibit/i ni, Butler, 1878, as type 

 species. 



P^rom his above mentioned work the following particulars 

 may be gathered : — 



1. "Male copulatory (U'gans : — The movable digit of both 

 pairs of copulatory forceps are composed of a single segment. 



2. "Female vulva as in Zeiiliruiiiu '' (i.e.: 'composed of 

 two pieces, a proximal hairy piece bearing the aperture, and 

 a distal usually polished piece'), but the proxiinal plate 

 divided into two distinct pieces, whereof the external partially 

 overlaps the internal. 



8. " Tarsi as in Zejihnnn'a'' (i.e. : ' distally narrowed, claw 

 terminal, the upper spine close to but behind the claw.' ") 



The characters numbered one and two rank, of course, 

 amongst the very best. As to the structure of the tarsi, it is 

 not possible so far to allow it the same imj)ortance as the 

 position of the dorsal spine seems to vary and the distance be- 

 tween it and the claw is a question of more or less. 



Yet the matter is far from being exhausted with these rough 

 notes ; further, valuable particulars may be obtained by 

 comparing the head of (JijlioHO»ia with that of iSii/ucropd'/i.'t. ]n 

 failure of material, the excellent drawings published by vom 

 Rathi and by Verhoeff- will answer the purpose, and the 

 reader will kindly refer to same to fully appreciated the 

 following" differences : —
