XXII.—On some Ethiopian Pentatomide of the Group 
Halyine. By E. Bercrotu, M.D. 
THE object of this paper is to give descriptions of some new 
or imperfectly known genera and species of Halyine. This 
group, which includes some of the most conspicuous Penta- 
tomide, has its headquarters in Australia, but it is also well 
represented in Africa, although many of the species are doubt- 
less still undescribed.
