Abstract
Rabbits immunised with venom of Vespa orientalis developed antibodies related to four of the protein fractions of the venom and gave well‐defined precipitin reaction in immuno‐electrophoresis and immuno‐diffusion. Three of the immuno‐proteins present were contained in the same electrophoretic fractions which containing the haemolytic principle of the venom. The fourth was identified as lysozyme. Paravespula germanica venom reacted with the antiserum showing two precipitation bands, indicating partial interspecies cross‐immunity.
