South African Grasshoppers. 543 
thicker than the pronotum and prominent above. Face dis- 
tinctly reclinate, forming an acute, but widely rounded angle 
with the fastigium of the vertex, [Frontal ridge in profile 
straight, regularly and gradually widened towards the 
clypeus, almost reaching the latter, suleate throughout, its 
sulcus confluent with the upper impression of the fastigium 
of the vertex. Fastigium of the vertex distinctly sloping, in 
the male longer Shan broad, in the female as broad as long, 
its margins strongly convergent forwards and running over 
to the front as the lateral margins of the frontal ridge ; the 
surface of the fastigium impressed, more so in the male. 
Temporal foveole undeveloped; the sides of fastigium 
vertical, high. Pronotum short and thick, distinctly, though 
broadly, constricted before its middle; fore margin very 
widely rounded; hind margin obusangulately rounded : 
median keel very feeble in prozona, more raised in meta- 
zona, cut by the transverse sulcus in the middle ; that sulcus 
is deep and straight, while the anterior sulci are scarcely 
perceptible on the disc; lateral keels strongly incurved, 
distinctly raised in the fore part of prozona only, disap- 
pearing between the sulci, very low, but clearly indicated by 
ivory-coloured callosities in the metazona ; surface of the 
dise distinctly rounded, especially so in the prozona ; lateral 
lobes higher than long, with the lower margin sinuate. 
Mesosternal lobes and their interspace decidedly transverse 
in both sexes, more so in the female. Metasternal lobes in 
the male distinctly, in the female widely separated. LElytra 
extending a little beyond the hind knees, hyaline through- 
out; the discoidal field without an intercalate vein. Wings 
broad ; radial veins incrassate ; discoidal area widened in 
both sexes, but much more so in the male. Fore and middle 
femora in the male distinctly incrassate. Hind femora in 
the male slightly incrassate, in the female more slender, 
gradually narrowed towards the apex. Hind tibize slightly 
widened apically, rounded, armed with eight outer and ten 
inner spines ; inner apical spurs about twice as long as the 
outer ones, but subequal to each other, strongly curved. 
Genotype: Lounsburyna capensis, sp. 0. 
This is a member of the essentially New World group 
Orphulz, which is represented in the Hastern hemisphere 
by only three known genera—Calephorus, Fieb., Froggattia, 
Bol., and Comacris, Bol.; there is no doubt that the South 
African fauna includes more undescribed genera. 
I have much pleasure in dedicating this genus to Mr. Chas. 
P. Lounsbury, Chief of the Division of Entomology, Pretoria.
