Comparison of paratypes in the author's collection prove 

 beyond doubt the synonymy indicated above. The male cerci 

 are unusually variable in this species and the differences noted 

 by Morse for those of sylvestris do not have even racial signifi- 

 cance. 



The penis in this species is nearest that of islandicus but has 

 the shaft shorter and thicker, the sheath (formed by the dorsal 



14 Although I recorded this species as mancus islandicus in 1932 from 

 Lansing, Hamburg and Bedford, Iowa and that name was consequently 

 included in the Iowa list published by Knutson and Jaques in 1935, I be- 

 lieve that the insect has not yet been taken in Iowa. Somes so labelled 

 material now in my collection though he did not record the species from 

 Minnesota. I believe that he used by mistake numbers for Iowa which 

 actually had been given for Minnesota localities. Several other equally 

 serious mistakes are known to have been made by that author who at that 

 time was far from well.
