I have not ascertained the sex of the specimen described, but 

 I think it is the female. A single specimen of another species 

 is in my collection ; in it the external ridges of the rostrum do 

 not run back into horns on the front, the elytra are foveo- 

 striate and without granules ; it seems to be a male ; if so the 

 exual characters are not very different in tiie sexes in this genus.
