The material of Avhich the present paper is a study was collected 

 by Dr. A. Donaldson Smith on his two expeditions into northeast 

 Africa, and presented by hira to the Academy of Natural Sciences 

 of Philadelphia. The first of the expeditions was made in the 

 years 1894 and 1895, and extended as far west as Lake Rudolf, 

 the whole account of which has been published in book form.^ 

 The last expedition was made in 1899 and 1900, the route being 

 by Lake Kudolf on through the unknown to the Nile. On this 

 last expedition but two specimens of Orthoptera were collected. 

 The total number of specimens of Orthoptera secured is 239, per-

 shortly be reported upon.
