PRELIMINARY LIST OF YORKSHIRE HEMIPTERA 

 — HETEROPTERA. 



W. J. FORDHAM, M.R.C.S., D.P.H., F.E.S. 



When the Victoria County History of Yorkshire was published, 

 the section on Entomology did not contain any list of the 

 Plant bugs, or Hemiptera, occurring in the County. This was 

 probably due to the paucity of records. Since that date, 

 however, much work has been done in the order. The writer 

 has been able to look through a series of notes and extracts 

 from various sources compiled by the late W. Denison 

 Roebuck, and has also drawn to a limited degree on the stocks 

 of records, unfortunately not very profuse, contained in 

 various entomological periodicals, and also in the British 

 standard works on the subject. A few of these are mentioned 

 in the short bibliography at the end of this paper. No doubt 

 a fuller search will reveal additional records. The bulk of 

 the material in this list, however, is the result of recent work 

 in the field by various Yorkshire entomologists. Foremost 

 among these must be mentioned the late Capt. H. V. Corbett, 

 who had compiled a preliminary list of his own captures, 

 which he intended to publish. It was thought better to in- 

 corporate these records with the result of other work on the 

 subject, and so to simplify the matter by publishing the 

 Yorkshire list as a whole, and at the same time to form some 

 sort of a tribute to the memory of one who was probably the 

 first serious worker in the Order in the County. His father, 

 the late H. H. Corbett, also took an interest in the Hemiptera, 

 and his records are duly incorporated. The late J. W. Carter 

 did some collecting in the Bradford district, and I have been 

 able to draw on his records and also those from the Keighley 

 district made by Mr. R. Butter fie Id. Other workers include 

 Messrs. E. G. Bayford, J. M. Brown, and T. Stainforth, and 

 the writer has been able to add his quota to the net result. 



The list would not have been made possible except for the 

 kind help of Mr. E. A. Butler, who has acted as referee, and 

 has verified the larger proportion of species herein recorded, 

 and has also helped with records of his own for the Whitby 

 district. The writer has also to acknowledge much assistance 

 from Mr. E. A. Newbery in the determination of several of 

 his records. 



The present instalment deals with the section Heteroptera 

 of the order, and gives records for 196 species out of a British 

 total of over 452 species. Much additional information on 

 life history and habitat can be added to these records when 

 the County list reaches a more complete state, and it is hoped
