158 ROLAND IIAYVVARD. 



carefully comjnired with Cliaudoir's type, the latter must be re- 

 garded as a synonym of the present species.* Both were described 

 from Texas, and the only two examples known to me are from that 

 State. 



It. obertliiiri n. sp. 



This name is proposed for the species which has heretofore been 

 regarded in this country as viridicolle Laf., and to which that name 

 Was assigned in my paper on the North American species of the 

 genus. The error was pointed c^ut to me by Mons. Oberthiir, and 

 it is with great pleasure that I dedicate the species to him as a 

 slight token of regard. 



B. timid II III Lee. 



To this species B. sordidulum Chaud. must be referred. 



B. contracluin Say. 



B. pilatei Chaud. is synonymous with this species. 



B, constricticolie Hayw. 



The arrangement of the dorsal punctures in this species is wrongly 

 described in my j)aper on Bembidium. The two specimens known 

 to me, when the description was written, were both badly rubbed, 

 and the arrangement of the punctures is seen, on studying other 

 material, to be practically the same as in semistriatum Hald. This 

 is also observable in the type when examined under higher power. 

 It should therefore be referred to the same group as the latter 

 species. 



* Since writing the above I have received word from Mons. 01)erthur tliat 

 hamiferum and viridicolle seem to him to belong to the same species.
