All examination of move than fifty specimens of n liaivcst sjtidcr in 

 various stages of development, taken along the banks of tlie Maumce 

 River, in Henry County, August 18, 1890, leads to the conclusion that 

 the form from Illinois described some years ago as lAohnuiim elc</<(H.s is 

 iin immature stage of the male of the present species. I have never 

 found any adult nniles. The forms described as vlegans are illustrated
