compressed forward on either side at the median sulcus, and the 
dorsum strongly depressed; elytra ovate, apices rounded; wings 
caudate; middle femora elongate, margins entire ; posterior angles 
of the lateral lobes of the pronotum hebitate. 
Entire length of female 14 mm.; pronotum 10°8 mm. 
Habitat.—Sikkim. Ind. Mus. coll. 
This species differs from sagittata in the subcuspidate frontal 
carinulae of the vertex ; in the tectiform dorsum, and slightly ele- 
vated undulate median carina forward. It is not at all typical of 
the genus Xistva, and approaches Paratettix in some respects. This 
species, like saggzttata and tricristata belong to a series by them- 
selves which really form a subgenus.

The type came from the same locality. The female in the 
Ind. Mus. coll. has the pronotum lengthily subulate, and the 
median carina between the shoulders strongly elevated in an 
obtuse gibbosity. The length of the pronotum 17 mm. 
Genus Lamellitettix, Hancock. 
Lamellitettix fletcheri, sp. nov. 
Near acutus, Hancock. Differing in the smaller stature: the 
vertex on either side more acute cuspidate; the frontal costa less 
protuberant between the antennae; median carina of the prono- 
tum bigibbulate, the first gibbosity very small and rounded placed 
between the sulci forward, the second gibbosity joined on either 
side with a strongly compressed subtransverse ruga; median carina 
on the hind process sinuate. The strongly elevated carinate tuber- 
cles on each side between the shoulders in acutus reduced in 
fletchert to short compressed carinulae; the posterior angles of 
the lateral lobes of the pronotum little acute produced in this 
species, whereas, in acutus, they are strongly transversely acute 
produced, the triangulate spine on each side having a broader 
base. 
Entire length of male 9°5 mm; pronotum 8-7 mm; hind fe- 
niora 4°5 mm,
