Obs. Species distinctissima, sectionera peculiarem in genere con- 

 stituens. 



Hermann's trivial name for this species has been restored, as well 

 in justice to that author as with the view of obviating the confusion 

 which has arisen from his chief description having been derived from 

 a different species. 



Mr. Westwood's Memoir was illustrated by numerous magnified 

 figures of the different species and of the details of their external 

 structure.
