DESCRIPTIOXS OF XEW SPECIES. 



BY ROLAND HAYWARD. 



Since the j)ul)lication of my paper on the North American- spe- 

 cies of Bembidium,^ I have had, through the kindness of Mons. 

 Rene Oberthiir, of Rennes, an opportunity to study the types of 

 those species of that genus described by Baron Chaudoir which 

 were then unl^nown to me, and the original descriptions of w'hich 

 were publislied in the appendix. I have thus been enabled to de- 

 termine their synonymy, wdiich entails, however, but few changes in 

 our nomenclature. This it is proposed to give in the present paper. 

 One new species has also been described, which, although represented 

 by an unique in my cabinet, seems too distinct to remain longer with- 

 out a name. My collection still contaijis several examples which 

 cannot be satisfactorily placed, but as they are mostly uniques and 

 are all referable either to group planatum or group variegatum, both 

 very troublesome ones, it seems best to let them remain undescribed 

 until sucli time as the limits of variation shall be more clearly de- 

 termined in the groups to which they belong.
