Tjipes in tlie British Museum. 



Closely allied to the last species, but at once recognised by its 

 blaciv antenuce and black-marked hind tibiae ; distinctly banded 

 abdomen, which is much less rufescent ; and the unifoi-mly 

 straighter radius; the average size is smaller and the abdomen 

 distinctly narrower to\vax-ds its base. It has much the facies of a 

 JS^omada. 



90. Orieiitotheronia acheron, sp. u. 



S . A stramineous species \\ith profuse black markings, the head 

 posteriorly constricted, the basal segment subquadrate and the 

 nervelet distinct. 



Length 8 millim. 



There can be no doubt that a single male I have seen is 

 abundantly distinct from both the preceding species, since the 

 basal abdominal segment is very much shorter and stouter, hardly 

 longer than apieally broad, the head narrower behind the eyes, 

 the nervelet distinct and the whole facies obviousl}' more " squat" 

 and compact. In its markings and sculpture, however, it exactly 

 corresponds with the male of the last-described species.

" The type of this genus looks like a red Xaatho)iimpIa or Thcronia. 

 In Dr. Ashiuead's system it comes near to the Xew Zealand genus
