Jiypc. — Chlorion {CMoi'ion) lohatut-n Y'AhYiciwii, Syst. Ent., 1775, p. 

 348.' 



Second culntal cell of the fore wing- much higher than broad. (Jlaws 

 with a single tooth near the middle of the inner edge. Anterior border 

 of the clypeu.s with teeth. Median segment with a stigmatal groove. 

 Stigma of the lirst dorsal abdominal plate placed in front of the mid- 

 dle. Tarsal comb of the female well developed. Body metallic, 

 glistening. (Plate IX, tig. 18; Plate X, fig. 22.) 



The genus ChloTion9^% established by Latreille does not in all respects 

 agree in diagnosis with the type," but as it was a monotypical genus, 

 and only later had compreasa added to it, and as the first reviser, 

 Jurine, retained lohatus as the type and removed compressa to his new 

 genus Ampulex^ this "assignment is not subject to subsequent 

 change."* Patton'" also takes this view.
