REPORT ON ZOOLOGY, MDCCCXLII : 
O. politum, from Van Diemen’s Land, C. gemmatum and sumptuosum, 
from Port Essington, are new. A twelfth species is C. loculosum, Newm. 
(EntomoL p. 369, Westw. Arc. Ent. p. 158), from Port Philip. The 
Scarites proper belong mostly to the peculiar form which was above 
mentioned, under the name Scariphites. One species only. Sc. sculptilis, 
does not belong to this, but is nearly allied to Sc. lateralis, Dej. The 
treatise includes also the new genus Gnathoxys (vide sup.) ; and there 
is a beautiful plate of the Sc. Schroteri, Schreib., on which, as the names 
given it of Heteroscelis and Hyperion are already occupied, the generic 
name Campy locnemus was bestowed by Westwood. 
Haliday has published, as his opinion on the systematic position of 
Adelotopus (EntomoL p. 305), that the almost wholly smooth antennae 
and compressed tarsi of the genus point out its situation among the W ater 
Beetles ; that it ditfers in essential points from the Gyrinidce, and for the 
present must, therefore, be joined to the Dytiscidce ; that Adelopus does 
not live in the water. The beetles are to be found, according to Davis’s 
report, under the bark of Eucalyptus (ibid. p. 306). There would be no 
reason against this opinion, did not the swimming tarsi form an essential 
character of the Dytiscidce, and the Adelotopus has none. Besides, the 
antennae are not smooth ; in Adelotopus, they are certainly more thinly 
haired, but in the allied genera they are just as thickly so as in the rest 
of the Carabi. 
Newman (ibid. p. 365), following Haliday, would establish for these 
beetles a peculiar order (!), in the same rank with the Carabites, Dytis- 
cites, and Gyrinites, and standing in the middle between them, under the 
name of Pseudomorphites. The number of the species of this group has 
received an accession, particularly those of the genus Adelotopus : A. 
hcemorrhoidalis Erich. (Arch. 1842, i. 126, 50), from Van Diemen’s 
Land, is perhaps the same with A. inquinatus, Newm. (EntomoL 366, 
50), from Port Philip; also A. scolytides, Newm. (ibid. n. 51), from the 
same place ; A. dytiscides (ibid. p. 365, note), from Adelaide ; and 
SilpJiomorpJia guttigera, Newm. (ibid. p. 367, 52), from Port Philip. 
Dytisci. — Rosenhauer (die Lauf und Schwimm-kafer Erlangens) has 
given a correct list of the Dytisci of Erlangen, and a comparison with 
other fauna. Erlangen has 89 species, Switzerland nearly the same 
(87 species) : Sweden, 103, and Mark Brandenburg 100, are richer : 
Lapland 73, and Paris 72, poorer. (According to the investigations of 
Apetz, Osterland [Gotha, or Upper Saxony] has 75 species ; the difference 
principally lies in the genus Hydroporus.) 
The true Colymbetes consputus, Sturm, has been determined by 
Kiesenwetter (Ent, Zeit. 88). It is distinguished from G. collaris, not 
only by its larger and broader form, but also in the marking of the 
elytra, and especially in the formation of the fore claws in the male. 
Two new European species of Hydroporus have been described by
