NOTES ON CARABIDZ, AND DESCRIPTIONS OF NEW SPECIES (No. 12). 
BY H. W. BATES, F.L.S. 
Genus MIZOTRECHUS, nov. gen. 
Gen. Trechico (Leconte) proxime affinis, at corpus robustius, magis 
elongatum, mentum medio dentatum, tarsi breviores, crassiores. Caput 
robustum, collo crasso, fronte foveis duabus latis leviter impressis signata. 
Mandibule longe exserte, modice falcate. Masxille longe exserte, intus 
spinis longis armate.  Palporum articulus ultimus ad basin penultimo 
latitudine equalis, gradatim acuminatus, Mentum dente mediano forte 
armatum. Thorax quadratus, postice leviter angustatus, angulis distinetis. 
Antenne breves, sub-moniliformes, articulis a 4° quadrato-ovatis, compresss, 
pubescentia a tertii apice incipientt. Elytra ad apicem lata, oblique sub- 
truncata, supra depressa, striis 8°% et 9% antice con junctis, postice paulo gra- 
datim divergentibus, 8°* per apicem ducta; interstitio tertio haud tripunctato. 
Pedes robusti, tarsis supra hirsutis, articulis crassis, ad basin via angustatis. 
Besides the dentate mentum, thick tarsal joints and square thorax, 
this genus differs from Zrechicus in the absence of the three setiferous 
punctures from the third elytral interstice. The mandibles and maxille 
also are much more exserted, approaching Diploharpus in this respect ; 
the terminal joint of the inner maxillary palpi is also very much shorter 
than the basal. 
I have compared the species in these respects with Zrechicus 
umbripennis, Lec., and Zr. fimicola, Woll. 
Mizorrecuus NOVEMSTRIATUS, 2. Sp. 
Elongatus, robustus, parallelopipedus, rufo-castaneus ; thorace magno, 
postice recte angustato, angulis posticis dentiformibus, prominulis, margune 
postice dilatato-explanato, supra timpunctato ; elytrorum striis omnibus 
impressis, indistincte punctulatis, ad basin sub-obliteratis, ibique 1% et 2nde 
in foveam basalem desinentibus, striola scutellari distincta. Long. 3 lin. 
ga. 
MizoTRecHUS LHVILATERIS, 2. sp. 
Minus parallelus, elytris oblongo-ovatis, thorace sesqui latioribus ; obscure 
castaneus, oris partibus, antennis, pedibus, abdomineque fulvo-testacers ; 
thoracis lateribus antice leviter rotundatis, angulis posticis distinctis, rectis, 
haud prominulis ; elytris sub-convexis, striis 1—5 acute impressis, impunc- 
tatis, basin haud attingentibus, 6¢—7"4 sub-obliteratis, 8°% postice flexuosa, 
tbique margine ocellato-punctato. Long. 24 lin. 
The sutural or first stria ends abruptly at a distance from the 
scutellum, the others are successively a little longer, but the third to
