Descriptions of New or Little-known Orthoptera. 403 



B. ocellata. As in the case of the closely allied genus Pneumora, the 

 identification is strengthened by our knowledge of the parts of the 

 Cape of Good Hope visited by Thunberg. 



The facies of the species is very uniform, but the different species 

 can be divided into three groups : one in which, in the known males, 

 the pronotum, although provided with a crest, is somewhat tectiform ; 

 the other where it is highly arcuate and compressed along the crest ; 

 the females are more difficult to define, but in one (longicornis) the 

 high carination and compression is very conspicuous. B. subulata, 

 n. sp., ? belongs to a third group which, when the <$ be known, will 

 possibly have to be included in a new genus. In this new species the 

 tegmina reach the hind part of the prouotuni, but in B. consobrina ? 

 there are also tegmina, but they are very rudimentary. The females 

 which I refer to the males have always been found in the same 

 locality, and it is very probable that they are rightly allocated. I am 

 adding three species. 



Key to the Species. 



MALES. 



A 2 . Pronotum tectiform. 

 B 2 . Pronotum with silvery bands ..... maculosa. 



B 1 . Pronotxini without silvery bands. 



C' : . Vertex, sides of pronotum and legs pubescent ; crest of pro- 

 notum not obtuse in front, discoidal part very coriaceous . unicolor. 

 Crest of pronotum not obtuse in front, discoidal part not 



coriaceous ....... immaculata. 



C 1 . Vertex, pronotum and legs glabrous. Anterior lobe of 

 pronotuin granular laterally, posterior roughly coriaceous, 

 crest with 4 notches in the anterior lobe . . . discolor. 



Anterior lobe closely granulate, serrate and very sloping, not 



granulate laterally ...... ocellata. 



Anterior lobe longer and with 6 or 7 sharp serrate teeth, 

 granulose laterally, the shiny granules extending to the 

 fore part of the hind lobe ..... consobrina. 



A 1 . Pronotum very highly arcuate. Anterior lobe of pronotuin 

 not tuberculate laterally, sub-coriaceous, anterior lobe not 

 serrate dentate, crest simple ..... intermedia. 



Pronotum sprinkled laterally with small shiny granular 

 tubercles ; anterior lobe strongly serrate dentate ; crest 

 tuberculate ....... longicornis. 



FEMALES. 



A 3 . Pronotum tectiform. 

 B' 2 . Anterior and intermediate tibiae smooth.
