Mesonotum concolorous, the inner carinae pale. Tegmina hyaline suffused 
with orange, veins alternately fuscous and white. Ovipositor not quite so 
short and stout as in the three preceding species. A large mass of waxy 
material between ovipositor and anal segment. 
One fema ira, South Island ; subalpine (T. Cockeroft). 
Holotype: Myers collection, Department of Agriculture. 
I have much pleasure in naming this species after its discoverer, to 
whom I am indebted for much valuable material. 
Genus 6, OxrARus Stal. 
Type: О. walkeri (Stal.). 
This cosmopolitan genusfis sufficiently differentiated by the characters 
included in the foregoing generic key. The five mesonotal carinae are 
usually very strongly marked. The male genitalia of the New Zealand 
forms show peculiar battle-axe-shaped genital styles and a complex aedeagus 
with some of the sharp processes projecting almost directly caudad instead 
of being recurved.
