Preliminary descriptions of some new, 

 australian Gryllids and Forficulids 



by 

 Eric Mj Öberg. 



During my scientific, biological expedition to Australia 

 1910 — 1911, I brought together a collection of about 20,000 

 insects. These are still waiting for their determination, only 

 some few groups having yet been worked out. The material 

 comes mainly from the western parts of the australian conti- 

 nent. When now starting my second australian expedition, 

 this time to the eastern parts, I hope to enlarge the ento- 

 mological material considerably. After my return, probably 

 in the end of next year, I intend to publish the whole ento- 

 mological result in the same volume (Kungl. Vetenskaps- 

 akademiens Handlingar). 



Here I give only some short preliminary descriptions of 

 the species of the groups, already worked, out by me.
