Observation: Tavijpiis vionilis Lin., a european species, 

 occurs in North- America (Wisconsin) according to Van der Wulp, 

 Tijdschr. v. Entora. 2^ Ser. II, 126. T. anmdatus Say looks very 

 nuich like T. monilis Lin., and if Mi'. Van der Wulp's identifica- 

 tion is correct, I should have taken both for the same species.
