Of the seven names enumerated by Jurine in the 

 Erlangen List (1801) as exponents of the new genus Trachusa, 

 the first, maculata, denotes an Anlhidium F. ; the last, 

 aterrima, a Stelis Pzr. ; and all the others are at present 

 included in Osmia Pzr. It will be observed that the only 

 species now generally assigned to Trachusa Jrn. (viz. 

 serratulae Pzr. 86-15) is not one of these seven original 

 exponents of the genus, although it is enumerated among 

 the species of Trachusa in the Nouv. Meth. Hym. (1807). 

 This, therefore, cannot be accepted as the Type of Trachusa 

 Jrn. (1801). Neither is the species figured by Jurine in
