South African Grasshoppers. 543 



thicker tliaii tlio proiiotum and [)romiiicnt above. Face dis- 

 tinctly reitliiiatc, torniing an acute, but widely rounded an^le 

 with the fastigiuin of the vertex. Frontal ridge in profile 

 straight, regularly and gradually widened towards the 

 clypeus, almost reaching the latter, sulcate throughout, its 

 sulcus confluent with the upper impression of the fastigium 

 of the vertex. Fastigium of the vertex distinctly sloping, in 

 the male longer than 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. 

 'J'eraporal foveohe undeveloped ; the sides of fastigium 

 vertical, high, Pronotum short and thick, distinctly, though 

 broadly, constricted before its middle ; foi'c margin very 

 widely rounded; hind margin obusangulately rounded: 

 median keel very feeble in prozona, more raised in raeta- 

 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 

 disc 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. Elytia 

 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 incr.issatc, in the female more slender, 

 gradually narrowed towards the apex. Hind tibiie slightly 

 widened ajjically, rounded, armed with eight outer and ten 

 inner spines ; inner apical spurs al)out twice as long as the 

 outer ones, but subequal to each other, strongly curved. 



Genotype : Lounshuryna captnsis, sp, n. 



This is a member of the essentially New World group 

 Orphulse, which is represented in the Eastern hemisphere 

 by only three known genera — Calephorus, Fieb., Froyyattia^ 

 13ol., 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. 

 r. Lounsbury, Chief of the Division of Entomology, Pretoria.
