DIPTERA 



I was for a long time very undecided about attempting a list of the 

 Diptera of Warwickshire, and am now far from sure that it is wise to 

 have done so. They are very insufficiently worked, so that it is inevi- 

 table that the list must remain very incomplete, and what is far more 

 important, the difficulties of the order are still so great that it is practi- 

 cally impossible to prevent errors creeping in, and a list that is incom- 

 plete and possibly inaccurate is of very doubtful value. I have however 

 ventured upon the task, and hope it may prove of some value and interest 

 to others attempting to understand these insects. There are not many of 

 our counties in which dipterists have lived and worked, so that it seems 

 a pity, as Warwickshire is one of the few, that an account of its insect 

 fauna should include no reference to the order. 



So far as I know, no one gave any attention to these insects in the 

 midlands until a few years ago when Mr. R. C. Bradley and I took them 

 up, and so far as I know no one else has yet done so excepting in the 

 slightest degree. This list therefore will be based almost entirely upon 

 the results of our own work. Mr. R. C. Bradley lived for some years 

 at Sutton Coldfield, and collected regularly in the Park, etc., so that 

 he had good opportunities of making an extensive list, and has kindly 

 furnished me with much information which he obtained at that time. 

 I have also frequently collected in the Park, and as neither of us has 

 done more than a little casual collecting in any other part of the 

 county, it becomes almost exclusively a Sutton list. I have therefore 

 only named localities when other than Sutton. We have both of us 

 given a considerable amount of attention to the Syrphida? and allied 

 families, and our work in that section may be taken as probably accu- 

 rate. Mr. Bradley has also made a considerable collection of Tipulidae 

 and its allies in the Park, and as Mr. G. H. Verrall has seen them their 

 names also may be taken as fairly reliable. We have also given attention 

 to various other families which will be found represented in the list, but 

 as I have preferred to omit uncertainties, so as to make it I hope more 

 trustworthy though necessarily shorter and more incomplete, I have 

 entirely omitted any reference to many difficult families such as the 

 Cecidomyids, Mycetophilids, Chironomidas, etc., only mentioning 

 those insects which are the most conspicuous and characteristic, and
