and kept by Mr. Smith in London for observation. This colony 

 is the subject of a paper by him in the 'Zoologist' for the same 

 year (x. 3699 to 3703). Abundant about Leeds ! Harrogate ! 

 Pannal! &c. In 1873 a hybernating female was found on the 7th

Vespa sylvestris, Scop. A nest taken on the moors near 

 Pateley Bridge in 1864 (E. Foxton-Firby in the 'Naturalist,' Oct.

I have taken the wasp at Pannal ! and at Leeds ! and a nest 

 was brought to me taken in July 1874 on a furze bush at Bramhope. 



Mr. Smith assures me that '-'this species not unfrequently 

 constructs an underground nest." (letter 28 June, 1878). 



Vespa arboreaj Smith, llie first known specimens were

 attached to a gooseberry bush, is given by him in the ' Zoologist ' 

 of that year (x. 3699 to 3703: the colony consisted of about
