NORTHUMBERLAND AND DURHAM. 115 



7. Atomaria riificornis, Marsh., Woll. Trans. Ent. Soc. Lond., 

 1857. 

 Long Benton, in June, but very rarely. 



Note. — The above will increase the number of our local species to one thousand five hun- 

 dred and twenty-seven. Of these a few, perhaps half-a-dozen, are from places (Talkin 

 Tarn, Lanercost, and Yetholm) not within, but very close to our limits. This I have done 

 to record the occurrence of very rare insects, or of species which are certain to be found in 

 our district when similar localities are examined.
