XXXVI. — Descriptions of Seventeen new Genera of Iclineu- 

 nionidje from India and One from Australia. By P. 

 Camehon. 



In this paper I have described a number of well-marked 

 genera of lchneunionid£e, mostly belonging to the Joppini 

 and the Heresiarachini. Very little has been published upon 

 the Joppini occurring in India, but in all probability they will 

 prove to be quite as numerous there as in the Neotropical 

 Zoological Region, which has hitherto been looked upon as the 

 lieadquarters of the group. Two genera of Indian Joppini 

 liave been described by Dr. Kriechbaumer in Ent.Nachtr. xxiv. 

 1898, Avhere he also revises the genera ; and there is a further 

 revision of them by Mr. W. H. Ashmead in Bull. U.S. Nat. 

 Mus. xxiii. 1900. The Heresiarachini are easily known by 

 their toothless mandibles. This tribe appears to be well 

 represented in India, but no species has hitherto been recorded 

 therefrom. The species are in the collection of i\Ir. G. A. J. 

 Kothney.
