254 Mr. Waterhouse on Carabideous Insects. 
XXVIII.—Carabideous Insects collected by Mr. Darwin 
during the Voyage of Her Majesty’s Ship Beagle. By 
G. R. WarerHovsE, Esq. 
[Continued from vol. iv. p. 362 of the Magazine of Natural History*.] 
Genus CAscELLIUvs. 
Mr. Curtis founds this genus upon two species brought by Capt. 
P. P. King, one from Chile, and the other from Port St. Elena, and 
described in the Linnzan Transactions, vol. xviii. part 2. 
Sp. 1. Cascellius Kingii, Curtis, Linn. Trans., vol. xviii. p. 183. 
Mr. Darwin’s collection contains four specimens of this species, 
three of which are from I. Chiloe, and the remaining one is from 
Yuche Island, Chonos Archipelago. They vary but slightly in co- 
louring, being of a green hue, more or less brilliant, and faintly 
tinted with brass colour; the legs are sometimes of an uniform pitchy 
red tint, but more commonly, it would appear, the thighs are of a 
darker colour than the tibie: in three of Mr. Darwin’s specimens 
they are pitchy black, obscurely tinted with reddish at the base. The 
antenne being imperfect in Mr. Curtis’s specimen, I may mention that 
they are short and rather thick ; if bent backwards they would about ~ 
reach to the base of the thorax; the basal joint is testaceous red, 
the three cr four following joints are more or less suffused with 
brown, and the apical joints are pale testaceous in all the specimens. 
Sp. 2. Feronia (Creobius) Eydouzxii.—This insect, described by 
M. Guérin-Méneville in the ‘ Magazin de Zoologie’ for 1838, p. 4. 
of Class IX., no doubt belongs to the genus Cascellius, and is closely 
allied to the C. Kingii; but from the figure and description, it would 
appear that it may be distinguished by its larger size, and the uni- 
form deep colouring of the legs and antenne. It is found in Peru, 
near Lima. 
M. Guérin-Méneville observes that his Feronia Eydousii “a beau- 
coup d’affinités avec le Carabus suturalis,” &c., “‘ mais, suivant M. 
Chevrolat, qui a vu le C. suturalis de la collection de Banks citée 
par Fabricius, notre insect en est fort différent;” he might have 
* At the end of this paper I intend giving a list of the species mentioned, 
with references to the pages in which they are to be found, for the conve- 
nience of those who may wish to refer to them; I shall then also correct 
any mistakes I may fall into,—provided I discover them. In the mean 
time I may remark, that the generic name Odontoscelis, proposed by Mr. 
Curtis and used by me in the first portion of this paper, had been previously 
employed by Germar for a genus of Hemipterous insects; I hope, there- 
fore, Mr. Curtis will suggest some other name. I am informed that 
Mr. Curtis’s generic name Cardiophthalmus has also been previously used, 
but cannot ascertain where. I find J had accidentally overlooked a speci- 
men of the Cardiophthalmus Clivinoides, Curtis, in Mr. Darwin’s collection. 
This specimen was “ found dead in the sea, 40 miles off the Straits of Ma- 
gellan.”—Mr. Darwin’s Notes.
