ORTHOPTERA OF MESOPOTAMIA AND PERSIA. 771 



there may be only one species. The specimen here referred to looks verj- much 

 Uke the $ of Trigonidium cicindeloides, Ramb., but the elytra are not so convex, 

 with false veins between the longitudinal nervation ; the antennae are testa- 

 ceous with the two first articles black. Legs testaceous, anterior tibiae, tarsi 

 and spines of the posterior tibiae feebly darkened ; anterior tibiae showing 

 no auditory foramen but a depression at base of the inner face, this being certainly 

 a character of the wingless condition of the species. 



The types of all the new species have been deposited in the British Museum.
