Descriptions of New or Little-known Orthoptera. 433 



femur varies in the two figures there given. In one example ( $ ) from 

 Augra Pequena, which I take to correspond to A. longipes, there are 

 four teeth in the inner side of the groove underneath, but only one on 

 the opposite leg ; two and one in the intermediate respectively, and 

 three and three in the posterior ; this number, however, varies, for in 

 one example from near the same locality the fore and intermediate 

 femora are spineless, and the number reduced to two outer and one 

 inner; the same thing occurs in another example from Becliuanaland, 

 bordering on the Kalahari, but on the right femur only. 



A. stratiotes seems to differ from the varietal forms here mentioned 

 by having two spines on the fore and hind tibiae underneath, and not 

 above the middle tibiae, as stated by Kirby (A.M.JST.H. iii, 7th series, 

 p. 143). 



Hcib. Damaraland (Augra Pequena ; Lower Svakop) Kalahari, 

 J. G. Alston. 1 $ ; 2 ? ? . 



ACANTHOPLUS LOANDAE, n. Sp. 



Testaceous with a faint metallic tinge ; prothorax as in A. longipes, 

 that is to say with three lateral spines in the part of the pronotum, 

 two in the posterior half and two in the centre of the hind margin 

 the surface strongly coriaceous ; abdomen with the hind part of the seg- 

 ments slightly plicate longitudinally, and having in the centre of the hind 

 border of the first three, and sometimes four, abdominal segments, a 

 long,- sharp spine, slightly hooked backwards at tip ; legs very long ; 

 anterior femora with two spines in the inner part of the groove under- 

 neath ; intermediate with one or none ; posterior with three. Number 

 of lateral spines of fore and hind tibiae variable ; those on the upper 

 groove of the intermediate number three inwardly and two outwardly. 



Length of body 31-41 mm.; of pronotum 17-18 mm.; of hind 

 femur 24-27 mm. ; of hind tibiae 25-30 mm. 



Hob. Loauda. 1 $ 2 ? ? . 



I have reasons to believe that, although labelled Loanda, these 

 examples were obtained further south, at or near Mossamedes. 



It is distinguished from A. longipes by the strong spines in the 

 centre hind border of the three first abdominal segments ; the fourth 

 does occasionally bear a spine also. 



ACANTHOPLUS BECHUANUS, n. sp. 



Testaceous, and occasionally fuscous, but always with a slight 

 metallic tinge ; face with a broad transverse band reaching from side 

 to side, but apt to disappear in dried specimens ; frons, cheeks, and 

 vertex sparsely punctate, the latter vaguely coriaceous ; pronotum with
