*^^ /^?^n ROEBUCK: ON YORKSHIRE WASPS. 



M. bicolor, (Jurine.) Mr. Smith has taken it in Yorksliire 

 (B.F.H. 1858, p. 184). 



Tribe DIPLOPTERA— Wasps. 

 This tribe is divided into two famiHes, the FAiinenidce, or 

 solitary wasps, and the Vespidce, or social wasps. Of the former 

 were enumerated in Smith's ' Cat. Brit. Hym.Acul.,' 1871, 2 genera 

 and 13 species (in 1876 increased to 14 by the capture of 

 Odynerus reni/onnis, Gmel., in the South of England) and of the 

 latter family i genus of 7 species. 



The British species are monographed by Mr. Smith in his 

 B.M.Cat., 1858, and the'7 social wasps well figured by Dr. Ormerod 

 in his 'British Social Vv'asps,' 1868, figures of the nests being also 

 given in the latter work. The student of wasps in general who 

 does not restrict his investigations by geographical limits is 

 exceptionally fortunate in having at his command the complete 

 monographs and splendid figures of De Saussure's 'Etudes sur la 

 Famille des Vespides,' 3 vols,, 1852 — 58. 



It will be seen by the following list that of the Vesjjidce all 

 the British species are recorded for our county, including the 

 Hornet j although I believe that its range does not extend 

 further north than the midland counties of England, all assertions 

 to the contrary notwithstanding. 



Odynerus gracilis, Brulie=0. elegans, Wesm. Near 

 Wakefield in July 1852 (F. Smith, Zool. x. 3626). 



O. Spinipes, (L.) Near Wakefield in July 1852 (F. Smith, 

 Zool. X. 3626). 



O. "pm^XeXum, (L.)=0. panel inns, Cmiis. Near Wakefield 

 in July 1852 (F. Smith, Zool. x. 3626). 



O. trimarginatus, Zeif. Near Wakefield in July 1852 (F. 

 Smith, Zool. x. 3626), 



O. Antilope, (Panz.) "Very abundant in Yorkshire" 

 (Smith, B.F.H. 1858, p. 211). 



Vespa Crabro, Z. The Hornet. I have seen three 



D4.
