Yorkshire Hymenoptera, Diptera, and Hemiptera Com- 
mittee.—The Committee have to deplore the loss of Mr. Edward 
Saunders, F.R.S., who for some years most willingly acted as 
Referee for Hymenoptera-Aculeata and Hemiptera-Heterop- 
tera ; and they have to thank the Rev. F. D. Morice, Mr. Claude 
Morley, and Mr. Percy H. Grimshaw, for their assistance in the 
determination of specimens. 
Not very much has been done this year; the cold, sunless 
season having been very unfavourable to all but the commonest 
species of Andrena and Bombus. In August and September 
there were some sunny days on which a few species were abundant, 
and about Doncaster Mr. H. H. Corbett found Mimesa bicolor in 
quantity on flowers of Torilis anthriscus, along with many 
Crabro cribrarius. On the same flower he took in the same 
neighbourhood Oxybelus uniglumis, which is new for the 
Yorkshire list. Mr. E. G. Bayford reports two other additions, 
Crabro (Crossocerus) palmipes g and Cecidonomus inimicus &, 
which occured along with Cvabro (Rhopalum) clavipes g ona 
willow stump in his garden at Barnsley. Mr. John F. Musham 
has collected a few species of bees at Selby, including the 
black form of the g of Psithyrus campestris, and Colletes dan wes- 
ana (a pair), a species quite new to the Yorkshire fauna. 
An interesting occurrence during the year has been that of very 
much dwarfed examples of Sivex gigas 9, scarcely half the usual 
size. One of these was brought to Mr. W. Denison Roebuck 
Igir Jan. r.
