This very distinct species has until lately been referred to the 
O. bullata, Schk., and Kunth has described a specimen from 
Jacquemont under O. bullata, remarking that it differed from 
Schkuhr’s figure in having a smooth rostrum. Tuckerman says 
that it has not been found in New England; my specimens are 
generally from the western parts of the state of New York. Sul- 
livant has found it in Ohio, and Lapkam in Wisconsin. I have 
three authentic specimens, from different sources, of the C. cylin¬ 
drica of Sckweinitz, all referable to G. bullata of Schkuhr.

This species has been confounded with C. Tuckermani, and I 
cannot quote with any confidence any other authorities than those 
I have mentioned above, I have three authentic specimens of it 
from Ilerb. Sckweinitz, under the name of C. cylindtdca : one sent 
to me by Kunze, received from Sckweinitz, another from the same 
source from Herb. Hooker, and one from Herb. Tuckerman, sent 
to him by Dewey, and received from Schweinitz under the name 
of O. cylindrica.
