The peculiar character of the rostrum, in conjunction with 



the normal character of abdominal segments and pectoral canal, 



is at once distinctive of this genus. The two spurs of the 



anterior and intermediate tibia3 are, I consider, mucros, the 



outer and larger one being in the usual position, the inner one 



i-oplacing the tuft of hairs often present when the tibia is a 



little dilated on the inner margin of the apex.
