HAEPALlDiE. LORICERA. 69 



Blemus, the four anterior tarsi of the males are dilated ; in the remaining ge- 

 nera the two anterior only : amongst the latter^ Sphodrus has four dilated joints, 

 Licinus and Panagaeus two, and the rest three — which are quadrate in Epomis, 

 Chlfenius, Ocides, Calathus, and Synachus ; more or less orbicular in Loricera, 

 Panagaeus, Callistus, Anchomenus, Platynus, Agonum, and Odontonyx ; and 

 heart-shaped or triangular in the other genera :— that the tooth or lobe, in the 

 centre of the mentum, varies considerably in form ; in some genera, above 

 placed in division B, it is sometimes so very slightly notched as to appear 

 truncate, varying even in individuals of the same species * ; while in others, 

 placed in division C, it is swollen into an obtuse knob, or occasionally consists 

 of a mere angular projection, gradually produced from the margin of the 

 lateral lobes of the mentum itself; thus approximating towards that con- 

 struction of the mentum in which the emargination becomes perfectly straight 

 anteriorly, as in Licinus, &c. The characters of the two last sections may 

 therefore be expressed thus : — B. The mentum furnished with a subtruncate 

 lobe in the centre of its notch, which is usually more or less emarginated ; — and - 

 C. The mentum generally bearing a central lobe which is more frequently acute 

 than obtuse, but never emarginated. I shall conclude by stating, that by some 

 accident in altering the disposition of the tables during the printing, the words 

 Licinus and Badister, in the table, page 66, were unfortunately transposed. 



Genus XXIV. — Loricera, Latreille. 



Palpi moderate: the terminal joint elongate, nearly oval and truncate at the 

 tip ; labrum short and rounded : mandibles very acute, denticulated at the 

 base : mentum with a notch anteriorly, in which is a simple tooth . labium 

 with a central rounded protuberance on its anterior edge: head rounded, 

 triangular : neck distinct : antennas slightly curved, pilose, with the five basal 

 joints irregularly globose-clavate, armed with long rigid hairs or bristles : 

 thorax obcordate, sessile : wings tvfo: claws simple : anterior tarsi'va. the males 

 with the three basal joints dilated. 



Loricera differs from all the other Geodephaga by the structure 

 of the antennae; the basal joint is very large, stout, elongate-cylin - 

 dric, the three following unequal, nodose, furnished with long rigid 

 bristles, the rest a little elongate, subcylindric, pilose : the neck is 

 distinct.. This genus has considerable resemblance to the Leisti, 

 but the suborbicular thorax and emarginate anterior tibiae readily 

 distinguish it from those insects.

• Especially in Poecillus cupreus, which has the lobe more frequently truncate 

 than emarginate ; whereas in P. assimilis the contrary appears to prevail. .
