This species is included on the authority of Prof. Pam- 

 mel as we have not seen an Iowa specimen. He says the 

 species occurs at Webster City in moist, sandy soil near 

 artesian wells, close to the Des Moines river. By letter, 

 Prof. Pammel also informs us that the species occurs at 

 Ames, Story City, and in Kossuth county.

We have seen no specimen of this species collected in 

 Iowa. We include it only on the authority of Gray's Man- 

 ual. Britton and Brown give the range of this species — 

 "Labrador and Quebec to Alaska, south in the Rocky 

 Mountains to Arizona," which indicates a range north of 

 our limits. Gray's Manual gives; "Minn., Iowa, north and 

 west ward."
