Specimens of this locust are at hand as follows: from Batanga, 

 one male and one female (F. H. Hope, Coll.); from Lolodorf, one 

 female (A. I. Good, Coll.); Banza Manteka, Belgian Congo, one male 

 (A. L. Bain, Coll.). 



Genus Cyrtacanthacris Walker. 

 Cyrlacanlhacris Walker, Cat. Derm. Salt. Brit. Mus., Ill, p. 550 (1870). 

 Acrydium in part, Olivier, Encycl. Meth., Ent., VI, p. 209 (1791). For synonymy 

 of genus see Kirby, Syn. Cat. Orth., Ill, p. 446 (1910). 



The insects, which are included in this genus, for almost a century 

 have been quite generally referred to Acridiiim. According to the 

 rules of zoological nomenclature, however, Acridiuni must be employed 

 to receive the various species of Tetrigidce so long referred to the 

 genus Tettix, as restricted in comparatively recent years. The next 

 available name seems to be Walker's Cyrtacanthracris. At least 

 seventy-five supposedly distinct species of the genus are recorded in 

 Kirby's Catalogue, /. c, pp. 446-454. 



28. Cyrtacanthacris lineata (Stoll). 



Gryllus Locusta linealus Stoll, Spectres Saut., p. 31, pi. 15&, fig. 57 (1813). For 

 further synonymy see Kirby, I. c, p. 450. 



The present collection contains five specimens, two males and 

 three females, which are referred to Stoll's lineata. The}' were taken 

 at Lolodorf and Batanga, and were collected by A. I. Good and F. H. 

 Hope. 



29. Cyrtacanthacris ruficornis (Fabricius). 



Gryllus ruficornis Fabricius, Mant. Ins., I, p. 237 (1787). For synonymy see 

 Kirby, I. c, p. 450. 



Specimens are at hand as follows: a single female bearing the label 

 "Banza Manteka, Belg. Congo, Coll. A. L. Bain, C. M. Ace. No. 

 4686," "Lolodorf, Kamerun, A. L Good, Coll., C. M. Ace. 5264." 



Genus ScHiSTOCERCA Stal. 

 Schislocerca Stal, Recens. Orth., I, p. 64 (1873), and numerous authors since. 



As in the case of the preceding, this genus is composed of large and 

 showy insects. It, however, is practically confined to the New World,
