ORTHOPTERA ACRIDIODEA. fi07 



locust is not known to have breecing places so far north : lie informs 

 me that the species was common at Enzeli at the end of May. and that 

 drowned specimens were frequently washed up on tlie shore of the 

 Caspian. 



32. Calliptmmis italicus, L. — Large number of specimens from different local- 



ities (Menjil, Kazvin, Baghdad, Amara, Mendeli). 



33. Thisocetrus Uttoralis, Ramb. — Amara, 30-10-17, 15-6 — 1-11-18 (Dr. 



Buxton); among herbage near Tigris, Amara, 1-11-17 (Mr. Evans). 

 The synonymy of this species is rather large, since I cannot agree with 

 J. Bolivar'*), who regards Euprepocnemis chirpentieri,^t.,ani E. Uttor- 

 alis, Ramb. as distinct species, the only difference being in the number 

 of spines on the hind tibiae, which is rather inconstant. As I have also 

 had the opportunity of seeing some of Walker's types in the British 

 Museum, I am able to add some new synonyms to the known ones and 

 the chief synonyms of this species are as follows : —
