Anterior wings extending beyond the abdomen, being tliin and diaphanous. Abdomen furnished with 

 a sting, and entirely black, except the first three rings, which are party-coloured, and mixed with yellow ; 

 the middle one being surrounded with that colour. Legs dusky orange, but when living they were 

 probably of a yellow colour. Breast black, but covered with hairs, making it appear of a greyish hue. 



This is the largest and finest species of the genus to which it belongs. Drury, con- 

 trary to his usual practice, is silent as to its habitat, and Fabricius states America gene- 

 rally. I have received it from Mr. Titian R. Peale of Philadelphia. That it is identical 

 with the Vespa tricincta of Fabricius I am enabled to state by an examination of the 

 individual contained in the Banksian Collection, now belonging to the Linna!an Society of 

 London, which was described by Fabricius.
