Descriptions of New or Little-known Orthoptera. 431 



GEN. ACANTHOPROCTUS, Karsch. 

 Berl. But, Zeits. xxxi, 1888, p. 66. 



This genus, includes only two species, namely, A. cervinus, Haau 

 (A. milttaris, White, and A. fortis, Walk., being synonymous), and 

 A. vittatus,- Walt., with A. capreolus, Pict., and A. howarthae, Kirb., 

 standing also in synonymy with the latter. I sent the specimen 

 described and figured by Pictet, and the second synonymy is admitted 

 by Kirby, who also states that H. fortis, Walk., and cervinus, Haan, 

 are identical ("On the Family Hetrodidae," A.M.N.H. 1889), but he 

 enters them nevertheless as distinct species in his ' Synonymic Cata- 

 logue of Orthoptera ' published in 1906. There can be no doubt as to 

 the identity of A. militaris, White, with A. cervinus. 



Both species seem restricted to the Karroo, Namaqualand, and the 

 northern part of the Cape Province and Bechuanaland. 



GEN. APHRACTIA, Kirb. 

 Aim. Mag. Nat. Hist, iii (7th ser.) 1899. 



The genus includes two species : A. diademata, Stal , which was 

 described and figured by Pictet as Acanthoproctus ibex (Mem. Soc. 

 Phys. Genev. xxx, 1888, p. 72, pi. 3, figs. 31 and 316), and A coronatus, 

 Karn. (Scliulz. Reis. Orthopt, ii, 1910, p. 118, pi. 2, fig. 4). 



Of the identity of A. ilex with A. diademata there can be no doubt, 

 as the specimen described by Pictet was sent by me to the late Henry 

 de Saussure. A. crassipes, Walk., is the same as A. diademata, teste 



Kirby. 



We nave five examples of A. diademata from Walfish Bay, and only 

 two of A. coronata from Angra Pequefia, quite close to the former 

 locality. I am somewhat inclined to consider the latter as a slight 

 varietal form of the former. 



GEN. ACANTHOPLUS, Stal. 

 Ofv. Vet. At. Forh. xiii, 1873, p. 39. 



In his ' Synonymic Catalogue of Orthoptera' (1906) Kirby enumerates 

 no less than nine species of this South African genus, he being respon- 

 sible for the addition of three new ones (Ann. Mag. Nat. Hist, iii 

 (7 ser.) 1899). 



The genus was created by Stal for Hetrodes longipes, Charp., a species 

 from Benguela, which occurs also within the limit of the South African 

 region i. e. south of the Cimeue River. In 1869 Walker published 

 the description of two species, A. pallidus and A. discoidalis, which in
