XXIV. ORTHOPTERA, II: GRYI.LACRIDAE and 

 STENOPELMATIDAE. 



By Dr. Achi.le Griffini, Milan {Italy). 



[In addition to the species of Gryllacridae described below, 

 Dr. Griffini has identified Rhaphidophora brimneri, Kirby (Steno- 

 pelmatidae) from Upper Rotung (2000 ft.) with certainty, attribu- 

 ting with some doubt specimens of the same genus from the Farm 

 Caves near Moulmein and from jungle on the Dawna Hills to this 

 species. The specimens from the Farm Caves were taken by Mr. 

 Gravely in holes in the floor, while large numbers of Diastrammena 

 unicolor, Brunner, occurred on the walls.]
