(see Vol. II. p. 240. note,), I have retained it as such. It is congenerous with 
Odyn. erassicornis Pz., belonging to Wesmael’s genus Symmorphus, which name 
must be rejected, being used by Klug for a genus of bees. , 
* This generic name is employed by Laporte, for a genus of Lamellicorn 
beetles.
