YORKSHIRE HYMENOPTERA IN 1879, 1880 AND 1881. lOI 



X Heptameris pygmaea Dbm. Mr. Peter Cameron informs 

 me that he has this insect — one of the parasitic Cynipidas — from 

 Scarborough. 



Family ICHNEUMONID.F. 



[The species included in the following list are those collected 

 and determined by Mr. S. D. Bairstow and Dr. S. C. Snellen van 

 Vollenhoven, and those recorded by Mr. T. Wilson in a paper on 

 "Ichneumonidje at York" published in the Naturalist, May 1881, 

 vol. vi., p. 153, together with a further series of captures by Mr. 

 Wilson in 1881 which have not hitherto been published. No less 

 than 59 species are here added to my former lists, showing that, 

 thanks to the labours of Messrs. Bairstow^ and Wilson, some good 

 work has been done in respect of this important group of 

 Hymenoptera. Mr. Wilson's captures were all made in the West 

 Riding, within a very few miles of York city, and in the deter- 

 mination of his insects he was assisted by Messrs. Bridgman and 

 E. A. Fitch. I add the remarks of Mr. Bairstow, introductory to 

 his report, which, owdng to his now having settled in South Africa, 

 wall probably be his last for some years. — W. D. R.] 



It is wdth feelings of painful regret that I handle my pen in 

 writing a report — which I fear will be my last for some years — 

 of this group. Regret, because I have to conclude my work so 

 recently begun, because I have to sever myself (though not my 

 heart and good wishes) from the midst of my many and dear 

 Yorkshire naturalist-friends. Regret also in the remembrance 

 that a. helping hand which was ever ready and willing to assist me 

 in any conceivable manner has been suddenly and irrevocably 

 withdrawn. A few short months ago Dr. Snellen van Vollenhoven 

 of the Hague wrote to me in the following strain: 'You need be 

 in no fear of troublhig me to name specimens for the Yorkshire 

 naturalists. Such assistance as lies in my power, this I do gladly 

 and affectionately give, and wish your hard working Union 

 God-speed and success in all branches.' Hours and hours were
