Clinidium Guildingii described. 
Palpi articulo extimo elongato, acuto. 
maxillares 
labiales 
}nondum investigati. 
Labium nondum investigatum. 
Mentum latum, utrinque tumidum. 
Antenne moniliformes, undecim articulate : articulo primo basi subat- 
tenuato, apice sequentibus crassiori, reliquis subglobosis, extimo sub- 
acuminato. 
Corpus apterum. Caput pedunculatum, ex oblongo-subquadratum. 
Oculireticulati nulli. Spatium laterale, levigatum, nitidum, subquad- 
ratum pone antennas oculos representare videtur.* Prothorar ex 
oblongo subquadratus, marginatus, lateribus rotundatis, angulis ob- 
tusiusculis ; supra medio longitudinaliter profunde et laté canaliculatus, 
basi utrinqué longitudinaliter foveatus, ut in Harpalidis plurimis. Co- 
leoptra oblonga. Pedes breves, longitudine fere wquales: cubitis 
apice intus subemarginatis ; sinu pectinato, utrinque calcarato ?+ tibiis 
apice calcari triplici ;t tarsis brevibus, pentameris, unguiculatis : un- 
guiculis brevissimis simplicibus. Sterna complanata: prosterno anticé 
constricto posticé emarginato-bifido ;_ mesosterno posticé bilobo, lobis 
divaricatis ; metasterno quinquelatero, angulo umbilicum mesostethii 
spectante. 
From its pentamerous tarsi, the sculpture of its prothorax, its neck, 
and the tendency to a notch at the inner side of the extremity of the 
cubitus, one is led to suspect some approximation in the insect before us 
to some of the Harpalide, or some other group of Linné’s genus Cara- 
bus, but as Mr. Guilding has not yet been able to investigate the maxille 
* Mr. Guilding used a powerful Dollond’s achromatic microscope in the ex- 
amination of this insect, but even with this aid he could discover no lenses or 
reticulations in the space here supposed to represent the eyes. 
+ From Mr, Guilding’s figure, it seems as if the lower part of the pectinated 
notch terminated in a spur, as in the Harpalide, &ec. 1 cannot discover the 
pecten in my specimen, but there is something like the spur; being gummed 
down, however, I cannot speak with confidence. 
} I can see nothing of a triple spur in my specimen, but the gum may have 
obliterated it, Mr. Guilding thinks that the pecten and the spurs are used by 
the animal to make its way out of the tree it passed its first states in.
