together is about equal in length to the elytra, in tlie latter 

 the elytra are considerably longer, Slereoderus is founded on 

 vei-y slight characters ; there is « a curious (endenctj to be armed 

 with one or more tubercles » on the front or centre of the ro- 

 strum. This is the best practical character I can find but I am 

 not sure that this is not a sexual one or that it is constant.

The cylindrical form of this species will at once distinguish 

 it from the last, with which, however, it agrees in the longer 

 elytra. In one of the specimens before me there is a short lon- 

 gitudinal impressed line between the eyes, as in Slereohorus, 

 followed by a single tubercle, in another specimen the line is 

 absent; in two others with narrower rostra there is no ap- 

 pearance of either line or tubercle.
