Several specimens, nine males and four females, of a rather small 

 locust collected by F. H. Hope at Batanga and by A. I. Good at 

 Lolodorf, are referred to Walker's Stenobothrns comptus, which forms 

 the type of the genus Chirista. 



These specimens look very much like our Orphulella pelidna (Bur- 

 meister).

This species is represented by one male and five females coming 

 from Batanga. There is also a second male from the same locality, 

 which has greater length of wing, but otherwise does not differ from 

 the description of this sex. All were taken by F. H. Hope in March 

 and April, 1914. C. M. Ace. No. 5293.
