XX IL — On some Ethiopian Pentatoraidae of the Group 

 Halyin^. By E. Bergeoth, M.I). 



The object of this paper is to give descriptions of some new 

 or imperfectly known genera and species of Haljin^e. This 

 group, which includes some of the most conspicuous Penta- 

 tomidffi, has its headquarters in Australia, but it is also well 

 represented in Africa, although many of the species are doubt- 

 less still undescribed.
