The original descriptions of the two unidentified species of

"Alatus, elongato-subovatus, subconvexus, nitidus, fortiter punctatus, bre- 

 vissime sparsim subargenteo a-qualiter setulosi, supra nigro-neneus, subtus 

 niger, antennarum articulis 2-4, labro, tibiarum apice tarsisque plus minusve 

 testaceo-piceis; capite punctato, f route inter antennas tuberculo nitido notato, 

 oculis subprominulis; thorace subconvexo, fere transverso, punctato, antice 

 attenuato, angulis omnes rotundatis, lateribus postice distincte crenulatis; ely-
