differs by its jnuch less i-obust and Jess con \ ex form, the long 

 slender antennae, the sniallness of the tubercles in the seventh 

 elytral interstice, the almost complete disappearance of the 

 tubercles on the front of the prostenium (wliich are not at all 

 pointed forward), its rostrum not at all concave, even at the apex, 

 cfec. Very fresh examples of this insect have the elytra thinly 

 clothed with short thick setw of a bright golden colour, especially 

 near the apex.

I am not sure of the sex of the specimen on which this de- 

 scription is founded, but believe it to be female. The structure of 

 the head and rostrum (the second and four'th carinie of the 

 i-ostrum ending abruptly between the eyes, tlie scrobes not ex- 

 panded as in L. biordinaius, &c.) in itself distingulslKvs the insect 

 from all the preceding species.
