ON TWO SPECIES OF COLEOPTERA INTRODUCED FROM EUROPE. 



By H. F, WICKHAM. 



During the summer of 1887, a specimen of the common 

 European Aphodms fossor Linn, was captured at Iowa City. 

 This species was introduced into the New England States 

 many years ago and has thus far been reported from New 

 Hampshire, Vermont, Canada (Ottawa and Trenton), and 

 Detroit, Michigan. I have not heard of its occurrence farther 

 west than Iowa City and it has been taken here but once. It 

 will be interesting to note whether it will increase in numbers 

 to such an extent as its relatives, A. grana7'ms, A. inquinatus 

 and A. jimetariiis — all originally European though now more 

 common than any of the native species in this part of the 

 State. 



After a recent visit of his to the South-western part of 

 Iowa, Prof. Shimek handed me, among other Coleoptera 

 which he had taken there, a species of Rhinoncus. This I 

 sent to Dr. Wm. G. Dietz, of Hazleton, Pa., a competent 

 authority on Rhynchophora, and he pronounced it a typical 

 specimen of Rhinoncus inconspcctus Hbst., a species well 

 known in Europe, but not until now noticed as a member of 

 our fauna. Two other European species of this genus are 

 already naturalized in Am.erica and it is likely that this also 

 has come to stay.
