The Sphex vaga of the Linnsean Cabinet is the male of M. 

 arvensis, but it does not agree with the description in the Fauna 

 Suecica ; in the Cabinet are also specimens of the Crabro vagus 

 of Fabricius, and in all probability the label has at some time 

 fallen off the pin and been attached to the wrong insect ; the 

 name given by Linnaeus to the female is therefore retained; 

 there can be little doubt of the Sphex vaga being identical with 

 the Crabro vagus, the description in the Fauna Suecica exactly 

 suiting that insect.
