This species is very close to L. internexus, but has the teguments 

 rather more delicate, the colour is paler ; it is usually of a broader 

 form, and the elytra are more ample, the sides posteriori; being 

 more strongly arcuate. The antennae have the first three joints 

 usually pale, but some examples have as many as seven pale joints. 



<5 . Legs black, with the base of the femora pale. 



5 . Legs yellowish, with the tarsi and sometimes the apex of the 

 tibiae black. 



Mr. Walker's type of L. divisus is merely a small example of his 

 L. planicornis ; both are females.
