South African Grasshoppers. 547 
(G. A. K. Marshall); five paratypes from Orange River 
Colony (G. L. H. B. Hamilton). 
The species is rather variable in its coloration, as is the 
case with most species of ¥Zolopus, and I have purposely 
described as paratype a specimen differing from the type in 
coloration, but it is easily recognisable by the very broad 
temporal foveolee with their lower margin more or less inter- 
rupted by puncturation; from A. thalassinus it may be 
also separated by its much thicker head, broader pronotum, 
and, especially, by the broad hind femora. There is in the 
Oxford Museum a specimen of this species from Salisbury, 
Mashonaland (G. A. K. Marshall), named by I. Bolivar as 
Epacromia contortipes, Bol., evidently a manuscript name. 
Some of paratypic specimens from Pretoria have the elytra 
shorter than in the type and the head thicker ; they much 
recall in their habitus a species of Gidaleus, but they do 
not present any definite character by which they can be 
separated from A. latus. 
ANZXOLOPUS, gen. nov. 
Closely related to olopus. Antenne rather thick, dis- 
tinetly flattened throughout, very feebly thickened towards 
the apex, in both sexes not reaching the hind angle of the 
pronotum. Head distinctly reclinate. Frontal ridge sulcate 
throughout or nearly so, with the margins thick, gradually 
divergent downwards. Fastigium distinctly prominent before 
the eyes, acutangular in the male, rectangular in the 
female ; slightly sloping and impressed. Temporal foveolee 
very strongly reclinate, almost vertical, scarcely visible from 
above, trapezoidal, strongly narrowed anteriorly, twice as 
long as the basal width, distinctly impressed, with margins 
sharp, but not at’all margined behind. Pronotum distinctly 
constricted before the middle ; median keel low, but distinct, 
cut by the transverse sulcus far before the middle; lateral 
keels in prozona developed, though sometimes very feeble, 
strongly convergent towards the first transverse sulcus and 
as strongly divergent behind it ; im metazona they are less 
developed, often smooth and replaced by pale lines, not 
reaching the hind margin; hind angle straight or even acute, 
with the apex not at all rounded ; lateral lobes asin olopus. 
Mesosternal lobes transverse, with a transverse interspace. 
Metasternal lobes separated in both sexes. Hlytra quite like 
those of -dolopus ; intercalate vein in the discoidal field 
thick, apically nearer to the radial vein than to the ulnar; 
interulnar area with two rows of cells, separated by a rather
