Individual variations. — The second male of this species has tegmina a little 

 shorter than the abdomen, with no veinlet between the diagonal and post- 

 axillary veins and 7 longitudinal veins in the lateral field. 



This species looks very much like the African A. morio, F., of which it differs 

 however by many small features, the most striking of which is the form of the 

 posterior metatarsus ( fi g. 31). 



Gen. — Grylltjs, L. 



Oryllus desertus, Pallas. 



Mesopotamia: Amara, April-May 1918, 3? ; Kut-el-Amara, 7-8-18, 

 1 2 ; Kurna, 20-3-18, 1 $ . 

 Persia : Enzeli, 1 $ . 

 All these examples belong to the macropterous form desertus, Pall. 



Gryllus domesticus, L. 

 Persia: Qazvin [4,000 ft.], 17-9-19, 2$. 



Gryllus tartarus, Sauss. 



Mesopotamia : Basra, 30-6-18, 1 $ ; 12-8-18, 1 2 ; Amara (W. E. Evans), very 

 common at light. 



Gryllus chinensis, Web. 



Mesopotamia: Amara, May-Sept. 1918, 5c? » 3$. 



All these examples belong to the Cerisyi form ; two of them are very large 

 with the veins of the lateral field of the tegmina almost straight and quite equi- 

 distant. 



Gryllus frontalis, Fieb. 



Me>3opotamia : Kizil Eobat, N.E. of Baghdad, 1 young individual. 



Gen. — Gryllodes, Satjss. 



Gryllodes lateralis, Fieb. 

 Mesopotamia: Amara, 2-11-17, 1 immature $. 



Gryllodes macropterous, Fuente. 



Mesopotamia : Amara, April-June 1918 (P. A. Buxton), 5 J , 1 $ ; 2-7-18 

 at light (W. E. Evans), 1$. 



Compared with a tjrpical male from Ciuadad Real (I. Bolivar in coll. Finot) 

 the cC examples cannot possibly be differentiated from it ; yet 3 of them are 

 ■smaller and less coloured, one being almost wholly pale yellow, but they 

 show absolutely no other character allomng us to consider them as a different 

 species. 



The females are a little smaller, very pale yellowish, with a small head. I 

 refer them with much doubt to this species although they may be considered 

 as a small variety with very recessive coloration, corresponding to the c? which 

 is above recorded. 



Gen. — Metioche, Stal. 



Metioche, sp. 



Mesopotamia : Amara, on herbage by Tigris (W. E. Evans, 19-9-18), 1 $ . 



This specimen must belong to one of the species described by STAL from the 

 oriental region (if. cokoptrata, M. tibialis, M. pallipes) ; it is quite impossible 

 ■io separate those species with the author's short diagnosis and very possibly
