4, Odontocera rugicollis, 
O. bisulcate primo intuitu similis, at differt inter alia femoribus posticis subito clavatis. Nigra; thorace fere 
cylindrico, dorso sulcis duabus haud profundis longitudinalibus, omnino grosse medio transversim rugulose 
punctato, disco rufo-castaneo; antennis brevibus, robustis, nigris; elytris modice abbreviatis, a medio 
dehiscentibus, apicem versus extrorsum paullo curvatis apice ipso obtuse truncatis, marginibus utrinque 
nigris punctatis, vitta mediana alba a basi usque ad apicem vitrea; corpore subtus nigro, episternis 
rufo-castaneis; pedibus nigris, femoribus tibiisque posticis basi albis, tibiis apicem versus paullulum 
sensim dilatatis extus nigro-pilosis. 
Long. 64 lin. 
Hab. Guatemata, Zapote (Champion). 
Much less elongated than O. sanguinolenta, and similar in form and colours to 
O. bisulcata; but distinguished from both by the abruptly clavate hind femora, which 
are nearly of the same form (relatively shorter) as in O. gracilis. Fach elytron forms, 
after the middle, a linear parallel-sided blade, slightly flexuous, the two blades being 
more distant from each other near the middle than at the apex.
