reference! that was missed by both Dr. Rabaud and myself, in 
which a locust (Dichromorpha viridis) was found by W. V. Warner 
bearing adults of a species of Scelio. 
Rabaud unfortunately refers to the Lepidoscelio which I de- 
scribed (loc. cit.) as a Chalcidid. It is a member of the Scelionide, 
belonging to the Serphoidea (Proctotrypoidea), an entirely different 
group of Hymenoptera, although the work of Xambeu, Giard, 
and Bordage is correctly stated as relating to Chalcidids. This

phenomenon of phoresy thus appears in members of both the 
Chalcidoidea and Serphoidea. Rabaud is also wrong in thinking 
that I put forth as new either the fact that adult Scelionids attach 
themselves to Orthoptera, or the hypothesis that they locate the 
eggs of the host in this way. On page 137 of my paper I have 
quoted both the fact and the hypothesis as previously published 
by Ashmead in 1893: the text is absolutely clear on this point. 
As the tiny species which has caused so much discussion has not 
before been figured I take this opportunity to add a drawing of it 
kindly made by Mrs. Brues.
