OF NORTHUMBERLAND AND DURHAM. 265 



Peryphus femoratus, Catalogue^ No. 1. 

 The type is rare; I have only met with a few specimens of it 

 on the banks of the Derwent, above Gibside. A pretty variety, 

 with the legs mostly pale, is more common, being the most abun- 

 dant species on the banks of upland streams, and occurring 

 throughout the year. — T. J. B.

spilotus, Steiyh. Illust, Mand., v., 385. 



M. J. Duval, contrary to the opinion of all recent naturalists, 



considers this to bo Carahus ustulatus, of Linnseus. As this 



opinion is subject to much dubiety, it appears preferable to adhere 



to the name by which it is more generally known. 



23. B. LUNATUM, Duft. 



Peryphus lunatus, Catalogue, No. 5. — P. ustus, Steph. Illust., 



Mand., ii., 14. 



This species aflfects the banks of upland streams. I have found 



it on the banks of the Irthing, in Cumberland, where it occurs 



most plentifully in June, but has been found so late as October. —
