NOTE ON THE ADULT HABITS OF SOME HYMEN- 
OPTEROUS EGG-PARASITES OF ORTHOPTERA 
AND MANTOIDEA. 
By Cuarues T. BRrues, 
Bussey Institution, Harvard University. 
In a recent number of the Bulletin de la Société Entomologique 
de France! Dr. Et. Rabaud has called attention to an omission in a 
recent paper of my own,” in which I failed to cite some observations 
of similar nature by French naturalists. In this paper I described 
an Indian Scelionid which attaches itself to the body of a locust 
and suggested that it probably had adopted this method of finding 
the eggs of locusts, upon which members of allied genera are known 
to be parasitic. 
As Dr. Rabaud has assumed a rather critical attitude, I think it 
worth while to review the matter briefly. In the first place I must 
admit that I was unfamiliar with the observations of Xambeu at 
the time of writing my previous note, although they were soon 
afterward called to my attention by Mr. Nathan Banks who cited 
them some years ago.? In the same paper, Banks gives another
