This genus may be placed after Melanterius, Er,, from 

 which, however, it is very decidedly differentiated by 

 its straight filiform rostrum, and the absence of the pec- 

 toral canal, which is replaced by a broad excavation 

 between the anterior and intermediate coxae ; the propec- 

 tus is exceedingly short ; the rostrum in repose appears 

 to extend to the first abdominal segment.
