VESPA SYLVESTRIS. 21!) 



shaped spot above the clypeus is larger, and deeply notched 

 above ; the first segment of the abdomen is visibly longer. 



First discovered by myself in 1836, near Wakefield, Yorkshire, 

 building nests in fir-trees. I possess a specimen of what I think 

 will prove to be the worker ; it differs from V. rufa in having 

 two spots on the scutellum and two on the post-scutellum. 

 This species has also been taken in Scotland, and M. de Saussure 

 has found it near Geneva.
