while the other is oriental in its distribution. About the same number 

 of species belong to each. Only one species of Schistocerca is found 

 east of the Atlantic, and it is supposed to have reached Africa from the 

 Occident, where it is also rather widely distributed. The genus con- 

 tains several well-known pests. 



30. Schistocerca tartarica (Linnaeus). 



Gryllus (Locusta) tartaricus Linn-eus, Syst. Nat. (Ed. lo), I, 432 (1758). For a 

 quite full synonymy of this species see Kirby, Syn. Cat. Orth., Ill, p. 459. 

 The species is represented by two males and two females. They 



come from the Congo (Antisdel). C. M. Ace. No. 2315. 



This insect is one of the chief migratory locusts of southern Eui-ope 



and northern Africa. It is also a widely distributed species in tropical 



America. A very extensive literature exists, based on this and other 



destructive and migratory locusts. 



Genus Abisares Stal. 



Abisares St.\l, Bihang, Svensk. Akad. Handl., V, (4), p. 29 (1878); Brunner, 

 > Ann. Mus. Genova, XXXIII, p. 143 (1893). 



The present genus was established for a single African species. 



31. Abisares viridipennis (Burmeister). 



Monochidium viridipenne Bur.meister, Handb. Ent., II, p. 626 (1838); Kirby, 



Syn. Cat. Orth., Ill, p. 466 (1910). 



Two males of a medium-sized locust from Batanga are referred to 

 Burmeister's Monochidium viridipenne, for which Stal proposed the 

 generic name Abisares. They were collected by F. H. Hope in April, 

 1914. C. M. Ace. No. 5293. 



Genus Coptacra Stal. 



Coptacra Stal, Recens. Orth., I, pp. 37, 58 (1873); Brunner, Ann. Mus. Genova, 

 XXXIII, p. 143 (1893); Bolivar, Ann. Soc. Ent. France, LXX, p. 624 (1902). 

 This genus is composed of less than a dozen species of small, mod- 

 estly colored locusts. One of their distinguishing characters is the 

 broad, fiat, coarsely punctulate frontal costa. 



32. Coptacra succinea Krauss. 



Coplacra succinnea Krauss, Sitz. Acad. Wiss. Wien., Math. -Nat. CI. LXXY'I, (i). 

 p. 34 (1877); Karsch, Berlin Ent. Zeitschr., XXX\'III, p. 92 (1893).
