ACHETID^. 



(9) GryLLODES SIGILLATUS, Walk. 

 Native name, Orong orong. 



Most commonly taken near to dwelling-houses ; not very 

 abundant. 



(10) Ornebius, sp. 



A very abundant species. It lives in the bushes of iron- 

 wood (Cordia suhcordata), and passes its early stages in a rolled - 

 up leaf. 



Neither of these species occurs on Christmas Island. 



(11) Gryllacris, sp. near signifera, StSl. 

 Native name, Chinghrck. 



This species also passes its early stages in the leaves of 

 the Cordia. When adult it appears to be carnivorous ; it has 

 exceedingly powerful jaws, and is credited with waging war on 

 the large centipedes. When put in a box with a centipede 

 it certainly fights with great vigour, and though it bites the 

 centipede, the fights that I have arranged ended fatally for the 

 Ghryllacris — but I believe that this is by no means invariable. 

 This species does not occur on Christmas Island, but the 

 allied G.rufovaria takes its place. The antennae are 150 mm. 

 long. 



(12) Phisis PECTiNATA, Guer. 



A fairly common species, usually found in the Cordia 

 bushes. It is a bright green when living. It is not found 

 on Christmas Island, but P. listeri, which occurs there, is very 

 nearly allied to it. 



. (13) CONOCEPHALOIDES SOBRINUS, Bol. 



The male is buff- coloured, and the female green during 

 life. The species is abundant, and commonly lives in bushes. 

 It is very musical. Does not occur on Christmas Island.
