A little pale brown beetle, variegated with gray on the sides. Its 

 snout is short, broad, and slightly furrowed in the middle ; there are three 

 blackish stripes on the thorax, between which are two

 stripe of light gray on the outer side, edged within b)- 

 a slender blackish line, and sending two short oblicjue 

 branches almost across each wing cover; and the fore 

 legs are larger than the others. Length from ^s to

 a smaller gallery than K u p s a 1 i s m i n u t a I )rur\', 

 and according to Harris, lives on the trunks of white 

 oaks. It has been recorded on white oak b\- Or
