Several decades ago, Professor August Forel† found in cocoons of the large Australian bull-dog ant, Myrmecia forficata Fabr., two specimens of a fine Eucharid. He recognized them as parasites of the ant larvæ and sent them to the English hymenopterist, Peter Cameron, who described them as Eucharis myrmiciæ‡. This was the first record of a Eucharid parasite of an ant, although several other genera have been reared subsequently from other ants and it seems likely that all of the Eucharidre are ant-parasites.
