Genus Eractheus. 

 Eractheiis, StSl, Ufv. Vet.-Ak. FOih. 1801, p. 190. 

 Type, E. lutulentus, St&l. 



Eractheus rubromarginatus , sp. n. 



Head, proiiotutn, scutelliim, and corium dull obscure 

 ochraceous, very thickly and somewhat finely darkly punc- 

 tate; lateral margins of pronotum, basal area of costal 

 margin to corium, and the connexivum sanguineous, the 

 latter with the incisures margined with black ; apex of 

 scutellum dull ochraceous ; membrane pale fuscous brown : 

 body beneath with the lateral margins of the sternum and 

 aV)domen sanguineous, followed by a broad l)lack submarginal 

 fascia, which is somewhat less strongly marked on the pro- 

 sternum and contains a large levigate pale ochraceous spot 

 near the anterior and intermediate coxie and a longitudinal 

 segmental scries of five similarly coloured spots on the 

 abdomen, disk of abdomen brownish ochraceous, legs and 

 rostrum pale brownish ochraceous ; antennae with the first, 

 second, and third joints stramineous, fourth and fifth fuscous 

 or testaceous, second, third, and fourth subequal in length 

 or third rather shorter, fifth distinctly longest ; greatest 

 length of head equalling breadth between eyes, the lateral 

 margins obliquely rounded ; scutellum with a small black 

 spot at each basal angle; membrane slightly passing the 

 abdominal apex; rostrum reaching the intermediate coxa;, 

 its apex black. 



Long. 8 to 8^ mm. ; exp. pronot. angl. 5 mm, 



Hab. Congo Free State ; Kambove {Nenve, Brit. Mus.). 



A somewhat elongate species compared with the others 

 belonging to the genus. Allied to E. boris, Dall., but much 

 narrower between the pronotal angles. 



Eractheus spinosus. 



Pentatomn spinosa, Sign. Rev. & Mag. Zool. 1851, p. 442. 

 ? Eractheus renb-alis, Bredd. Soc. Ent. xviii. p. 115 (1908). 



Hab. Usambara (fide Bredd.) ; S.E. Rhodesia ; Gaza 

 Land, Chirinda Forest {Odeiidaaland Swynnerton, Brit. Mus.) ; 

 W. Africa. 



If I have rightly understood Breddin's description, and 

 with a comparison of a large number of specimens received 

 from localities on the West African Coast to Rhodesia, 

 there is little di>ubt .is to the above syuonvmy.
