The Genus Acrida. 187 



Amycics achromoptcrus. Karsch, 1896, Stett. Ent. Zeit., 

 250. 



Patria. East Africa : Nyassa, Milanji {Karsch). 



The antennas are more slender than m the preceding 

 species, and also longer ; the depressed basal part is not 

 serrated on the outer margin. The wings are plain and 

 not coloured. 



Note. — Since the above went to the press, I have seen Mr. Kirby's 

 work on a " Collection of Lociistidse, formed by Mr. W. L. Distant in 

 the Transvaal" (ante, p. 57), which will necessitate the modification of 

 some points in this paper. H\\q Acrida t^irritaoi Mr. Kirby coincides 

 with my Acrida nasnta, whereas his Tryxalis nasnta coincides with 

 my Acrida, variabilis; his Acrida (iigantea,Fness\y, is the striped 

 form of my Acrida nasuta. I have inadvertently omitted Acrida 

 madecassa, Brancsik (1893, Jahresb. Ver. Trencsen, xv, p. 186, from 

 Madagascar), wliich appears to me to differ little, if at all, from 

 Acrida nasuta, Linn. The two species Acrida rendalU, Kirby, and 

 Acrida aspersata, Kirby, do not clash with any described by me.
