Stal (Hem. Afr. iii.) distributes the species belonging to this

trum^ including the genera Nabis and Metastemma and their 
allies ; Henicocephaliday with the thorax trilobate and the heme- 
lytra entirely membranaceous, including only the genus Heni- 
cocephalus (EnicocephaluSy Westw.) = Systelloderus (Blanch.) =
