I can learn, has never been taken in England {7), 

 and begin with HyLeus, which follows it.

(%) Apis rostrata, Lin. In some M. S. notes in an inter- 

 leaved copy of the Systema Naturce, which belonged to the 

 celebrated Mr. Gray, it is observed by Miller upon tliis species, 

 " In Anglld inveniri audio." But as this Is only hearsay evi- 

 dence, it may very possibly be a mistake, I have never seen 

 it in any cabinet of English insects.
