cate at the apex. The subgenital plate in the female has the 

 apex notched on each side, thus forming three blunt teeth ; 

 supra-anal plate rounded at the apex. Male not known. 



Colours. — Bright-green above; the anterior margin of the 

 pronotum yellow on the sides. Tegmina yellowish-brown. 

 Lower surface pinkish. Hind femora with three dark trans- 

 verse bands, their lower surfaces orange-red. Hind tibiae 

 orange-red, with a broad band of yellow, margined on each 

 side with black, near the proximal end ; the spines black. 



Length, $ 31mm.; of pronotum, $ 6 mm.; of hind 

 femur, $ 18 mm. 



Locality. — Mount Torlesse, Canterbury, at elevations of 

 about 3,000 ft. (A. Cockayne).

Closely allied to the Mesemhria, but the fastigium is always 

 defiexed, and passes insensibly into the frontal costa, there 

 being no dividing-ridge between the two. Also the pronotum 

 is not flat, but rounded, and lateral carinas are rarely present. 

 In the species of the Northern Hemisphere the spines m the 

 outer row on the hind tibise are 9 to 14 (very rarely 8), while 

 in the New Zealand forms the number of spines is from 6 to 8. 



Chiefly American, but a few species are found in Europe, 

 and one in Africa.

As the characters I gave in my former paper were taken 

 from Nevv" Zealand insects they will serve for those of Bra- 

 chasjns, but I will add a few others. 



The antennae in the female are about as long as the fore 

 femora, longer in the male. The tegmina are never absent, 

 but rarely project beyond the first abdominal segment. The 

 tympana are distinct, but hidden by the points of the tegmina. 

 The subgenital plate in the female has a long subapical point, 

 which is hidden between the bases of the lower division of the 

 ovipositor. The supra-anal plate in the male and the sternal 

 shield in both sexes are variable — by the sternal shield I mean 

 the fused sterna of the mesothorax, the metathorax, and the 

 first abdominal segment. In all the species it is either as 

 broad as or broader than long, in which the genus resembles 

 Bradyotes more than Podisma (= Pezotettix). But from 

 Podisma it is distinguished by the pronotum being without any 

 trace of a keel and emarginate behind, as well as by the strong 

 prosternal tubercle, which is transverse and truncated ; also,
