South African Grasshoppers. 545 
West, Cape Province, 25. iv. and 28. x.1917; another 
cotypic maleis from Jansenville, Cape Province, 18.ix. 1917. 
This interesting insect is very easily recognisable by its 
habitus, shape of the head and pronotum, and venation of 
elytra and wings. 
5. Comacris semicarinatus, Gerst. 
There are in the British Museum two specimens from 
Durban, 1902 (/. Muir); the species has not been pre- 
viously recorded from South Africa. 
6. Afolopus latus, sp. n. 
?. Of the size of A. thalassinus, but more robustly built. 
Antenne not reaching the hind margin of the pronotum. 
Head distinctly thicker than the pronotum in its fore part, 
a little shorter than the pronotum, moderataly reclinate. 
Face and cheeks smooth, very sparsely and finely punctured. 
Frontal ridge thick, convex, feebly impressed at the ocellum, 
sparsely punctured below the latter and densely above it ; 
margins of the ridge very obtuse, gradually divergent from 
the fastigium downwards, disappearing just below the 
middle ocellum. Temporal foveole only half as long again 
as broad, narrowed apically, very feebly impressed, rugu- 
losely punctured ; their lower margin indistinct, interrupted 
by the punctures. Fastigium of the vertex a little broader 
than long, almost horizontal, rotundato-pentagonal, with a 
distinct transverse impression near the base ; its margins 
very slightly raised, obtuse. Pronotum distinctly constricted 
just behind the fore margin ; its disc distinctly convex in 
the prozona, almost flat and strongly dilated in the meta- 
zona; median keel rather thick and low, cut by the transverse 
sulcus distinctly before its middle; hind angle obtuse, 
rounded, with its sides straight (not convex, as in A. thalas- 
sinus); the dise of prozona smooth, that of the metazona 
smooth in the fore part and in the middle, and densely 
punctured behind and on the sides; lateral lobes not much 
higher than long, very feebly narrowed downwards, with the 
fore margin sinuate, lower margin obtusangulate in the 
middle, hind margin straight and almost vertical; the fore 
lower angle obtuse ; hind angle straight, scarcely rounded 
at the apex; the prozona distinctly, and metazona densely 
punctured. Sternum as in 4d. thalassinus. Meso- and 
metapleurze very coarsely rugulose. Elytra rather broad, 
extending a little beyond the hind knees ; their venation as 
in A. thalassinus. Hind femora short and thick, not reaching
