♦Species marked by an * are given on the authority of Mr. Billings. 



\ This species was described in Yol. 3 as B. grandis. Hall. The name being preoccupied 

 by Vanuxem, was changed to D. ampla, Hall, in Pal. N. Y. Yol. 4, p. 17. 



t S. ampla, has been regarded as a synonym of S. Headleyana, This may be proved by 

 farther comparisons ; in the meantime they are here separately recorded.
