Bruner: Orthoptera from Africa. 97 



species are found in the material being studied and upon which I am 

 reporting. 



Genus Acrida Stal. 



Acrida Stal, Recens. Orth., I, pp. 88, 95 (1873); Burr, Trans. Ent. Soc. Load., 

 1902, pp. 149, 155. 



8. Acrida propinqua Burr. 



Acrida propinqua Burr, Trans. Ent. Soc. Lond., 1902, pp. 157, 171. 



Five specimens belonging to the genus Acrida are at hand'. They 

 are referred to Burr's propinqua. Two males and one female come 

 from Batanga, where they were taken by F. H. Hope. One female 

 bears the label "Lolodorf, Kamerun." It was collected b}' A. I. Good. 

 A third female bears the label "Congo, Antisdel." The latter speci- 

 ment belongs to C. M. Ace. No. 2315. 



Genus Odontomelus Bolivar. 



Odonlomehts Bolix'ar, Bol. An. Soc. Espan. Hist. Nat., XIX, p. 309 (1890); 

 Karsch, Berlin. Ent. Zeitschr., XXXVIII, pp. 53, 61 (1893); Burr, Trans. 

 Ent. Soc. Lon:l., 1902, p. 154. 



9. Odontomelus bifrensis Bolivar. 



Odontomelus bifrensis Bolivar, Mem. Soc. Espan. Hist. Nat., I, p. 219 (1905). 



Three males coming from Batanga are placed here. They were 

 taken by F. H. Hope in April, 1914. C. M. Ace. No. 5293. 



Genus Rodunia Bolivar. 



Rodunia Bolivar, Bol. Mem. Soc. Ent. Belg., XVI, p. 99, note (1908); Kirby, 

 Syn. Cat. Orth., Ill, p. 139 (1910). 



The representatives of thig African genus bear a general resemblance 

 to various species of Orphulella and allied American forms. Like 

 them, they also appear to be genuine "grasshoppers" and are fairly 

 common wherever found. Seventeen species are recognized by Kirby 

 (/. c, pp. 139-40). 



The genus, as at present accepted, is composed of forms which were 

 originally referred to at least four separate genera by their respective 

 authors. Even now there seems to be quite a confusion as to their 

 exact afifinities, and only for convenience in assisting in their deter- 

 mination is the annexed imperfect key for their separation added.
