base, shoulders scarcely prominent, with an elevated carina to-

Obs. "Allied to the genus Barynotus, but chiefly differs in 

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

 tellum." — Transcribed from Schonherr.

I have found many specimens of this insect on Mercurialis 

 perennis in 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.
