Genus KiPTOETUS. 

 Ripiortus decisus. 



Camptopus decisus, Walk. Cat. Het. iv. p. 165. n, 30 (1871). 



Riptortus longipes. 



Alydus lonffipes, Dall. List Hem. ii. p. 473 (1852). 

 Ahjdmfavo-iittatus, Stfil, (Efv. Vet.-Ak. Forli. 1855, p. 30. 2. 



Dallas gave Brazil as the habitat of his species, and this 

 locality was clearly erroneous, as pointed out by Stal (En. 

 Hem. iii. p. 95, 1873) ; I possess specimens from East Africa 

 which agree with both the type of Dallas and the description 

 of Stal. 



Riptortus serripes. 



Cimex serriins, Fabr. Syst. Ent. p. 709 (1775). 



Abjdiis rubustus, Dall. List Hem. ii. p. 473. u. 13 (1852). 



Camjjtottis svrdidiif, Walk. Cat. Het. iv. p. 167. n. 40 (1871). 



The type of Fabricius is in the Banksian Collection con- 

 tained in the British Museum. The species identified by 

 Dallas as Alydus serripes (List Hem. ii. p. 474. n. 15, 1852) 

 is not conspecific. 



Genus Serinetha. 



Sert'netha ahdominalis. 



Lygaus ahdominalis, Fabr. Syst, Rhyng. p. 226 (1803). 



Var. Serinetha tuprobanensis, Dall. List Hem. ii. p. 401. u. 6 (1852).
