ARCANA ENTOMOLOGICA. 
oblique line towards the tip of the elytra; there is also a marginal 
row of punctures at the base of each side. The teeth of the fore 
tibiie are obtuse, and the middle tibise have a single acute tooth on 
the outside, at the tip. 
I also possess a species of this group, which I had considered to 
be identical with Sc. Silenus, with which it agrees in size, but from 
which however it differs, in having the elytra more regularly rounded; 
the mandibles are also differently toothed, wanting the small tooth 
on the inside near the tip, and the left mandible having one large 
central simple tooth, with a small lobe towards the base, whilst 
the right mandible has two strong central teeth. If this should 
ultimately prove a distinct species, it may receive the name of 
Scarites (Scaraphites) confusus. 
My Sc. sculptilis is, by M. Reiche, in the article above referred 
to, considered as closely allied to Scarites lateralis, Dej., supposed 
to be a native of the East Indies, and belonging to Dejeaffs 5th 
section of the genus. 
M. Reiche has also added descriptions of two new Australian 
species, belonging to my genus Gnathoxys # , namely— 
Species XVII .—Gnathoxys obscurus , Reiche. G. nigro-seneus subnitidus, pronoto subro- 
tundato canaliculato angulis anticis baud porrectis, elytrorum disco punctato-striato; 
striis octo geminatis interruptis; lateribus et apice crebre et irregulariter punctatis. 
Long. 14 mill. (= fere 7 lin. mens. Angl.) Hab. Australia, Swan River. Mus. Reiche. 
Species XVIII. — Gnatlioxys cicatricosns , Reiche. G. elongatus ccneo nitidus, pronoto sub- 
ovato canaliculato, angulis anticis baud porrectis, elvtiis profunde, late et irregulariter- 
impressis, apice rugoso plicatis. Long. 13 mill. Hab. Australia, Swan River. Mus. 
Reiche. 
Mr. Newman has also published the description of another species 
of Carenum in the Entomologist + for September last (p. 869). 
Species XIX .—Carenum loculosum . C. nigrum fronte profunde longitudinaliter bisul- 
cata, prothorace transvcrsd lunato medio longitudinaliter sulcato ; elytris foveis magnis 
pravd dispositis asperis; tibiis anticis dentibus 2 longis externis spinisque 2 intends 
armatis; tibiis intevmediis dentibus 5—6 externis minutis spinis 2 apicalibus. Long, 
corp. .625 unc., lat. .25 unc. 
It is perfectly distinct from Carenum Spencii, Westw. 
Mr. MacLeay has recently forwarded to Mr. Hope a Carenum, 
under the name of C. 4-punctatum, which agrees with Bonelli’s 
species (C. Bonellii mihi), except that the central fossula of the 
pronotum is scarcely transversely striolated, and the oblique impres¬ 
sions on each side at the base are scarcely distinct. It is a native 
of New South Wales, and was found under stones at Ulawarre. 
* M. Guerin Meneville showed me, whilst in Paris, two Indian insects apparently belonging 
to this genus, possessing the same structure of the fore feet. 
+ I regret to mention that the proprietors of this work are under the necessity of discon¬ 
tinuing its publication with the number which will appear on the 1st of November.
