This new form of Adelium I have a satisfaction 

 in naming as the type of a new genus, giving it the 

 specific name of Walckenserii, in honour of Baron 

 Walckenaer, the celebrated Apterologist. To the 

 same genus belong the following species, viz. 

 Thoracophorus Audouini, Depressus, iEneipennis, 

 and Walkerii, all of them inhabiting New Holland, 

 and in my possession.
