Herbst's figure so happily expresses the characters of this little 

 insect, that it seems not easy to mistake it; yet his description 

 would agree perhaps as well with Apion foveolatum, which, as I 

 observed before, was sent me for it from Sweden. It is princi- 

 pally distinguished from the three preceding species by having 

 its rostrum thicker from the point where the antennas are insert- 

 ed to the head (a circumstance not omitted in the figure above 

 quoted); by its thorax so slightly punctulate as to appear nearly 

 without points under a single lens ; by its elytra, which, taken 

 together, approach more to an obovate shape : besides this, three 

 furrows are very conspicuous between the eyes. It is not un- 

 common upon Vicia sepium, and I do not find it upon any other 

 plant. Major Gyllenhal sends it as Attel. punctiger of Paykull : 

 1 had before regarded that as synonymous with Ap. aterrimum. 

 but I yield to his authority.
