806. Celina australis, Clk., M.C.—Oblongus, angustulus, elongatus, parallelus, 
depressus, minus nitidus, ferrugineus, elytris abdomineque piceis, illis lateribus 
dilutioribus ; prothorace elytrisque fere eequaliter breviter strigulosis, his seriebus 
duabus punctorun distinctis, strigulis ad. apicem obliquis. Long. 52, lat. vix. 
23 m.m. 
The few specimens I have seen of this distinct species seem to be all females. 
The peculiar parallel elongate form, and the distinct, regularly distributed short 
fine strize, or scratches, of the upper surface separate it at once from the other 
Australian species. 
Australia, (Melbourne, Rockhampton). 667. 
807. Copelatus hydroporoides, n. sp.—-/’em., Oblongo-ovalis, haud elongatus, sub- 
depressus, minus nitidus, ferrugineus, plus minusve infuscatus, prothoracis lateribus 
elytrorumque basi dilutioribus, capite sat conspicue punctulato ; prothorace medio 
late subleevigato, ad angulos posteriores punctate; elytris crebre, eequaliter forti- 
terque punctatis. Long. 5, lat. 23 m.m. 
I have seen only a single female, in bad condition, of this very distinct species ; 
it bears a gond deal of resemblance to the European Hydroporus ferrugineus, 
(No. 636). 
New Caledonia. 684. 
808. Copelatus gracilis, n. sp.—Oblongo-ovalis, angustulus, sat parallelus, sub- 
depressus, ferrugineus, elytris abdomineque castaneis, illis basi dilutiore, antennis 
pedibusque testaceis; elytris seriebus tribus punctorum, preetereaque parce subtil- 
issime punctatis. Long. 4, lat. 2 m.m. 
The male differs from the female only by a very slight thickening of the front 
and middle tarsi. 
Australia, (Rockhampton). 661. 
809. Copelatus victorize, Clk., M.C.—Ovalis, angustulus, minus depressus, haud 
parallelus, pone medium evidenter latior, ferrugineus, elytris testaceis, pectore 
abdomineque nigricantibus, elytris seriebus tribus punctorum sat distinctis, versus 
apicem sine strigulis transversis distinctis. Long. 42, lat. 2: m.m. 
The male is distinguished from the female only by a slieht thickening of the 
front and middle tarsi. The species is readily distineuishe] from C. gracilis by 
the differences in form and colour.
