Labium nondum investigatum. 



Mentum latum, utrinque tumidum. 



AntenncE monilitbrmes, undecim articulatae : articulo primo basi subat- 



teuuato, apice sequentibus crassiori, reliquis subglobosis, extimo sub- 



acuminato. 



Corpus apterum. Caput pedunculatum, ex oblongo-subquadratum. 



OcttZj'reticulati nuUi. Spatium laterale, Isevigatum, nitidum, subquad- 



ratum pone antennas oculos reprsesentare videtur.* Prothorax ex 



oblongo subquadratus, marginatus, lateribus rotundatis, angulis ob- 



tusiusculis ; supra medio longitudinaliter profunde et late canaliculatus, 



basi utrinque longitudinaliter foveatus, ut in Ilarpalidis plurimis. Co- 



leoptra oblonga. Pedes breves, longitudine fere aequales : cubitis 



apice intus subemarginatis ; sinu pectinate, utrinque calcarato ?f tibiis 



apice calcari triplici ;J tarsis brevibus, pentameris, unguiculatis : un- 



guiculis brevissimis simplicibus. Sterna complanata : prosterno antice 



constricto postice emarginato-bifido ; mesosterno postice 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 Harpalidae, or some other group of Linne's genus Cara- 



bus, but as Mr. Guilding has not yet been able to investigate the maxillae 



* Mr. Guilding used a powerful DoUond's achromatic microscope in tlie 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 Harpalid<B, &c. I 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.
