The only specimen* known to have been taken in Illinois 

 was collected years ago by Robert Kennicott, and is now in the 

 collection of the National Museum at Washington. In 1878 

 Messrs, Rice and Davis secured a specimen from northern In- 

 diana and described it as a new species (ii*. circulosa), which, at 

 a later date, they reduced to the rank of a variety. Kennicott's 

 specimen was examined by them and pronounced identical with 

 the Indiana specimen. The specimen at Washington is labeled 

 R. areolata capita, and a study of more material from this region 

 will probably show this name to be the right one for Illinois 

 examples of the species.
