PTYELUS GBOSSUS. 65 



S. Africa regarding the above species, and likewise 

 regarding the C. ruficornis noted below, were too general 

 to be of any definite service as to their habits or measures 

 of prevention. I am only able, therefore, at present to 

 add a figure of the very beautiful specimen of the P. 

 morbillosus which was sent me, and to suggest that notes 

 of the life-history of both species would be of much 

 interest. E. A. 0. 



Another species of Locust received from S. Africa is 

 Cyrtacanthacris ruficornis, Fab. : this, in general appear- 

 ance, resembles the common Egyptian Locust (Acridium 

 peregrinum, Oliv.), which likewise occurs in S. Africa.
