Leugth (the rostrum included) 14 '/a mi^i- — Black; very 

 densely covered all over (with the exception however of 

 the mouth and a triangular space at the front margin of 

 the rostrum) with greenish white scales, which show a 

 golden lustre according to the light. Over the whole 

 surface small black dots are present, which generally bear 

 a short scale-like seta. The club of the antennae with 

 the exception of its base is grayish black. 



The hinder part of the head is depressed , and the space 

 between this depressed portion and the transverse groove 

 in front of the eyes a little broader than long and pro- 

 vided on the middle with a longitudinal narrow groove 

 which widens a little on the rostrum. The head and 

 rostrum are dispersedly punctured ; the punctures on the 

 rostrum are placed somewhat closer together than those 

 on the head. The scape of the antennae is a little longer 

 than the two basal joints of the funicle taken together; 

 the first joint of the funicle is shorter than the 2nd , the 

 2nd as long as the 3rd and 4th taken together, the 7th 

 joint as large as the 4tli ; the club is elongate ovate ,
