Coreidae. 



Anoplocnemis enrvipes^ F., causes a certain amount of injury to cotton plants 

 in some districts by sucking the stems. It has been found puncturing the young 

 tender shoots of mahogany in the plantations near Zomba. 



Pentatomidae. 



Antestia variegata^ Thunb., damages coffee berries to a considerable extent. 

 Atehcrra stirtira, Westw., sucks the new shoots of mahogany. 



Pyrrhocoridae. 



Dysdercus nigrofasciatus, Stal, is a major pest of cotton, which it damages both 

 by sucking the seeds and by staining the lint. It is generally distributed in the 

 Protectorate. Odontopus conjusus, Dist., attacks Cotton in the same 4 way, but 

 appears to be more limited in its distribution, occurring only in the low-lying hoi 

 districts.
