This is, so far as we know, the only record of a Eulophid 
with an ant host. Although it cannot be stated definitely that 
the Eulophid is a primary parasite of the ant, it would seem 
that such is probably the case as none of the ant larvae showed 
signs of parasitism by any other species. 
Among the Chalcidoidea it is not unusual to find several 
parasites developing in a single host. In the Chalcididse and 
Proctotrypidse, where polyembryony occurs the number may 
reach a hundred, perhaps more. But this is not a case of poly- 
embryony, for here both sexes occur within the same host in- 
dividual. Whether all the parasites in a host larva are offspring 
of the same mother or whether two or more females have ovi- 
posited in one host (epiparasitism of Haviland) cannot, of course, 
be determined from our material. Among the Eucharidse there 
are three records of this multiple parasitism: 
Pseudochalcura gihhosa Provancher. (Kost-Camponotus her-
