5. S. india, sp. nov. 
Resembling S. producta but slightly stouter in stature. Body 
fuscous, pale variegated, the carinz: of dorsum flavo-maculate, the 
tibia with pale annuli. Vertex subequal in width to one of the 
eyes, the frontal carinz on each side little compressed and subacute. 
Pronotum anteriorly somewhat subangulate, posteriorly extended 
beyond the knees of the hind femora about as far as the tibial apices, 
but not so lengthily attenuate as in producta; dorsum conspersed 
with granules ; depressed and uneven, between the sulci forwards 
subfossulate on each side, between the shoulders bearing subelevated 
longitudinal costate protuberances, humeral angles unarmed, behind 
the shoulders bifossulate, and presenting a pair of rounded subele- 
vated nodules, again another pair somewhat fused together appear 
posteriorly opposite the middle of the hind femora which are indis- 
tinct ; posterior process stout at the base and acuminate toward the 
apex ; median carina rather incrassate, unevenly undulate, anteriorly 
at the margin little protuberant and subtuberculate : lateral lobes at 
the anterior margin armed with small tubercles, the posterior 
margin little laminate’ outwards, and armed with a distinct, acute 
spine on each side, directed transversely but little curved forward. 
The posterior femoral margins entire, the posterior tibia armed with 
minute denticles, the margins dilated towards the apices; the first 
article of the posterior tarsi dilated but not so widely as in producta.

Genus CHTHONOTETTIX, Hancock.* 
1. C. palpatus, Stal, Ofv. Vet. Akad. Forh., p. 57, 1877. 
= Chthonius palpatus, Bolivar. (Plate XXI, fig. 3.) 
Body sparingly granulose, fuscous, obscurely variegated with 
flavous. Vertex distinctly narrower than one of the eyes, the anterior 
carina rounded oblique; eyes globose; frontal costa roundly 
protuberant between the antenna, narrowly sulcate and divided 
little above the posterior ocelli, the latter situated between the lower 
third of the eyes, conspicuous in profile ; antennz inserted scarcely 
* The name Chthonotettix was proposed by the present author 
(vide Genera Insectorum, 48me Fasc. Orthoptera, Subfam. Tetrigine, 
p- 26, 1906) to replace Bolivar’s preoccupied genus Chthenius.
