 rotundatis, sulculo anteriori dilatato, punctato, fovea laterali punctata ; elytris sat profunde punctato- 

 striatis, interstitiis subaequalibus ; metasterno convexo sequali, postice vix punctato • tibiis sicut in

Passalus agnoscendus, Percheron, in Guerin, Mag. Zool. 1841, t. 78. f. 2 \ 

 Hab. Mexico \ Jacale, Durasnal, Parada [Salle), Jalapa (Hbge). 



2. Vindex sculptiKs. 



Mediocriter elongatus, sat depressus ; elytris late sulcatis sulcisque eleganter transversim punctatis, interstitiis 



5°-9 m et omnibus versus apicem cariniformibus. 

 Long. 21 millim. ; thorax 5i, elytra 12 millim. long. 



Hab. Guatemala, Purula (Champion). 



The frontal carinse, as in V. agnoscendus, curve sharply round and end in long teeth 

 which project over the clypeus and enclose a small semicircular space or fovea; at each 

 end of the clypeus there is also a large and acute tooth. The metasternum shows no 

 trace of flattened central plate, but the sides present a rather wide finely punctulate- 

 pubescent depression.
