below it terminated in the general surface of the sand. Probably the cricket protects itself 

 in this way against centepedes, a species of Scolopendra being abundant under the 

 stones. 



ORTHOPTERA OF THE SEISTAN MISSION. 



We have lately received at the Museum a small collection of insects made by a 

 collector attached to the Seistan Boundary Commission under Sir A. H. McMahon. 

 The specimens appear to have come mostly from the British side of the Perso-Baluch 

 frontier ; but they have no exact localities. It struck me that it might be interesting to 

 compare this collection, made in a sandy and barren district at the other extremity of 

 the Indian Empire, with my own from Ramanad ; but I found it impossible to identify 

 species belonging to any other group but the Orthoptera, although some general remarks 

 on the collection are given on later pages. The following is an annotated list of the few 

 Orthoptera, 1 taken. 



Mantidje — 



I. PSEUDOMANTIS MACULATA (Thunb.), ? $ . 



Widely spread in the Oriental Region. 



2. Blepharopsis mendica (Fabr.). 



Though the only specimen obtained is immature, I have no doubt as to its identity. 

 We have a male from Sind, identified, dissected and carefully carded by Wood-Mason, 

 which agrees closely with the descriptions. B. mendica is recorded from the Canaries, 

 N. Africa and N.W. Asia. 



AcRIDIIDiE — 



3. ACRIDIUM PEREGRINUM, Oliv. 



The common Locust of Northern India. 



Also two other species which I have been unable to identify. 



Gryllid^e — 



5. Gryllotalpa vulgaris, Latr. 



A large series, most of the specimens being of considerable size. 



6. Gryllus gracilipes, Sauss. <? 9 . 

 I think the two specimens obtained belong to this species, but cannot be certain. 



7. Liogryllus bimaculatus (De Geer) 2. 



The spots at the base of the tegmina are rather obscure in the one specimen ob- 

 tained. This is one of the commonest of the Indian Crickets. 



1 There is also an Earwig {Lapidura riparia Pall.) in the collection. See Burr in Joum. As. Soc. Bengal, 1905, p. 29.
