7. Hydrobius æneus Germ. var.? (Paracymus Thoms.) 
Portimao, Lagos. Under the name of Iydrobius œæneus, there 
exist in collections two or three distinct species, (vide Redten- 
bacher Faun. Aust. 2" ed. p. 104) of which the synonymy will be 
very difficult to unravel; the one found by M. van Volxem is 
perhaps the I. punctulatus Sturm, which is perhaps erroneously 
considered a synonym of /1. æneus.
