26 A CATALOGUE OF THE INSECTS OF 



8. H. plumbea, Wat., Trans. CI. VI., 226 ; D. Sharp, 1. c. 114. 

 Rare. Sea coast near Hartley. 



9. H. luridipennis, Mann., Nat. Hist. Trans. I., 131 ; D. Sharp, 



1. c. 117. 



Not uncommon. Long Benton, Banks of Irthing, &c. 



10. H. londinensis, Sharp, 1. c. 118. 



Rare. Team side, near Ravensworth, Mr. J. Hardy. 



11. H. hygrotopora, Kz., Trans. CI. VI., 226; D. Sharp, 1. c. 



120. 



Banks of streams, &c. Not rare. 



12. H. elongatula, Grav.; Trans. CI. II., 80; D. Sharp, 1. c. 



121 ; H. autwmnalis, Hardy, Trans. CI. II., 83. 



Very abundant throughout the district. 



My types of H. autwmnalis, named by Mr. Hardy, were deter- 

 mined by Mr. Jansen to be H. gregaria and H. occulta. I have 

 since examined Mr. Hardy's series and find that (although allied 

 species are included) the bulk of the specimens are to be referred 

 to H. elongatula. Into this error he may have been led by Erich- 

 son comparing autumnalis, in shape and size, with small speci- 

 mens of H. elongatula. 



13. H. volans, Scriba ; D. Sharp, 1. c. 122. 



Quite as common as H. elongatula, and, like it, generally dis- 

 tributed.

One specimen, from Henhole, taken in June, by Mr. J. Hardy. 



15. H. tibialis, Heer. ; D. Sharp, 1. c. 125 ; H. nivalis, Trans. 



CI. II., 77.

 Exceedingly abundant amongst decaying algas on the sea 

 shore.
