Tetrigine in the Oxford University Musewm 241 
Originally described from a male example from Mada- 
gascar under the genus Zelmatettix. A second specimen 
in the Oxford Museum from the same locality, being a 
‘female, allows me opportunity of revising my opinion of 
this species. This species resembles Paratettix scaber from 
Africa, and it may be quite possible that it is this species. 
The antennze are inserted between the inferior part of 
the eyes, as in Hedotettix. 
4. H. celebicus, sp. nov. 
Avery slender-bodied species; greyish-cinereous or flavous, 
variegated with fuscous. Head little exserted ; vertex scarcely 
narrowed forward, narrower than one of the eyes, sulcate on each 
side of the median carina, not at all ampliate toward the front ; 
frontal costa slightly arcuate, the face in profile not at all sinuate, 
rami divided distinctly above the posterior ocelli, moderately 
suleate. Pronotum truncate anteriorly, subtectiform between the 
shoulders, posteriorly lengthily acuminate, the process extending 
beyond the femoral apices; median carina percurrent, somewhat 
acute, little elevated between the shoulders; dorsum granulate ; 
the prozonal carinz parallel ; posterior angles of the lateral lobes 
turned down and narrowly rounded. Elytra with the apices some- 
what widely rounded ; wings strongly caudate. Anterior femoral 
carine straight ; intermediate femora, in the male, little ampliate 
toward the bases, in the female, subnarrowed ; the first tarsal articles 
with the first and second pulvilli acute-spiculate, the third much 
longer than the second, and straight below, the apices acute. Length 
of body entire, male and female, 11-14 mm, ; pronotum 9-10 mm. ; 
posterior femora 4-5 mm.

2. C. rotundatus, sp. nov. 
Fuscous, the legs sometimes flavous or fusco-variegated ; vertex not 
produced beyond the eyes, strongly narrowed forward, about equal 
in width to one of the eyes, fossulate on each side, in profile little 
roundly elevated above the eyes ; the frontal costa strongly roundly 
produced in advance of the eyes, the rami dividing above the
