I have only one specimen of this pretty little species, which 

 will be found to have a leading character, if it be not a sexual 

 peculiarity, in its strongly curved anterior tibiaj. In the 

 (faintly) tricarinate prothorax and the sculpture of the elytra 

 it approaches 0. concretus. The species of Oxyops have in 

 general a shortly oval contour, the apex of each elytron ap- 

 pearing to be produced into a short blunt mucro ; but this is 

 almost entirely owing to a gradual thickening of the sutural 

 interstice as it approaches its termination.

 crebre punctato, in medio haud carinato, basi lato, margine postico 

 ferrugineo-squamoso ; scutello ovali ; elytris ampKs, convexis, 

 humeris prominulis, punctis magnis seriatim impressis, interstitiis 

 sat angustis, tertio basi tuberculo elevato alteroque postice in-
