YORKSHIRE HYMENOPTERA IN 1 87 9, 1880 AND 1 88 1. 93 



were determined for him by Mr. J. B. Bridgman, and some by 

 Mr. E. A. Fitch. The list includes also records ofspecies which 

 have been named for myself by Mr, Peter Cameron. 



The list of Yorkshire Tenthredinidse having been very much 

 enlarged through Mr. Wilson's labours I have judged it advisable 

 to present here a complete catalogue of the known Yorkshire 

 species, distinguishing with a cross ( x ) those which appear for 

 the first time, and referring to my past report in the case of those 

 before recorded. It is the more necessary to give the complete 

 list on account of certain rectifications in the nomenclature of my 

 first report which are required. The arrangement and nomen- 

 clature are according to Mr. Cameron's catalogue of British 

 Tenthredinidse.— W. D. R.] m 



TENTHREDINA . 



Tenthredo livida L. See first list, p. 27 : second list, p. 64. 



At York in 1S79 and 1880, occurred amongst the tall rank 

 herbage which grows luxuriantly along ditch-sides. In such 

 places Heracleiim sphondyiium and Spiroea ulniaria grow, and it 

 is fond of settling on the leaves of those plants (Wilson, Entom., 

 p. Z^). 



Abundant about Huddersfield and Edlington Wood near 

 Doncaster, where it was noticed in August, 1879: specimens 

 collected by Mr. Bairstow in these localities were named by Mr. 

 Cameron (Roebuck). 



X T. atra L. One specimen near York, 1879 or 1880 

 (Wilson, Ent, p. 90). 



T. zonata Pz. See first list, p. 27. 



X T. bicincta L. Four examples (two males and two 

 females) of this pretty species taken near York in 1881, on floMcrs 

 of Heracleimi sphondyiium (Wilson). 



T. mesomela Z.=viridis Kl. nee L. 



Mr. Cameron informs me that the records given in the first 

 list (see p. 27 of this vol.) under the name of T. viridis L., are 

 in all probabihty referable to this species (W. D. R.)
