Say's brief description of terminalis applies only to ohscurus Howard, 

 as the characters, "head yellowish, antennae blackish, terminal joint 

 white" effectually eliminate aU other North American species or 

 forms belonging to this group. The species seems to be fairly dis- 

 tinct horn. Jiaminius in the shape of the head, although merging with 

 it in coloration through the subspecies californicus Girault. This 

 considerably greater range in coloration of terminalis is characteristic 

 of many North American Hymenoptera as compared with the corre- 

 sponding species or genera of the Old World.
