 record, and the Committee have been much indebted to Messrs. 

 Grimshaw, Morice, Morley and Saunders, for acting as Referees.

 G. T. Porritt, H. J. Robson, W. Denison Roebuck, and Walter 

 Withell have been the collectors, and Messrs. H. C. Drake and

 Butterfield's reports on Bradford Hymenoptera and Mr. J. H. 

 Ashworth's on Bradford Diptera have appeared in print, and 

 contain numerous additions to the recorded Yorkshire Fauna. 

 The Rev. W. C. Hey, whose sudden decease this year is a great 

 loss to this Committee, pubhshed notes on the Humble Bees and 

 Wasps of West Ayton. Among the numerous additions to the 

 Fauna, the most striking are : — Bombus smithianus, an interest- 

 ing Arctic form, found by Rev. W. C. Hey, at West x\yton ; 

 Ammophila sahulosa, a most conspicuous fossor, taken on Stren- 

 sall Common by Mr. W\ Hewett ; Tenthredo colon, in a wood 

 within Leeds city boundary, by Mr. A. Hodgson, who also found 

 it again at Roundhay ; the rare bee Nomada lathburiana. which 

 he discovered last year.
