having the rostrum and thorax carinated ; and without a scu-

I have found many specimens of this insect on Mercurialis 
perennis 'm a shady wood near Mickleham, Surrey, in June, which 
have the alternate interstices of the elytra distinctly elevated. I 
have also found many specimens by brushing amongst grass in 
meadows, and in moss in the woods of Yorkshire, that have the 
alternate interstices of the elytra scarcely or very slightly elevated, 
but agreeing exactly with the former in every other character ; 
the latter are considered by Gyllenhal and Schonherr as varieties, 
and after a most careful examination of numerous specimens I 
have no hesitation in citing them as such. 
I possess foreign specimens from Germar.
