WASPS. 



Common Ground-building Wasp. Ves2)a vuhjaris, Linn. 

 Hornet. Yespa crahro,lA\VLi.; and five other species. 





Nest of Tree Wasp, after sketch from original specimen by Ed. Dimensions, 8 in. 



across by 7^ deep.* 



The most remarkable insect appearance of the past season was that 

 popularly known as the " Wasp plague." The very unusual prevalence 

 of Wasp presence was reported from almost every one of the many 

 localities in England, from which replies to my enquiries were for- 

 warded to me, and though the infestation was not so general in 

 Scotland, it was exceedingly troublesome over some large districts, 

 notably by the Moray Firth ; in the Lothians, and in some of the 

 islands on the west of Scotland. 



* As the tenants of the nest were not identified at the time, I cannot say with 

 certainty whether it is that of Vcspa sylvestris or V. norvegica.
