I possess all the species intended by my list, except about five, 

 and I possess five or six others at present unrecognised ; it seems 

 strange that so many species of such conspicuous insects as Tipulce 

 should remain uncertain, but the genus is a difficult one to begin un- 

 derstanding, and only a few persons have ever collected them at all 

 exhaustively in any part of the world. 



T. nigra, L. : common in marshy places, especially fens and large 

 swamps. 



T. confusa, V. d, Wulp, and marmorata, Mg. • I am very uncertain 

 about these species ; the one which occurs abundantly at Barton, near 

 here, and has even appeared in my garden, was quite unknown to the 

 Austrian Dipterists last January. I require more of the allied species. 



T. signata, Stseg. : just after my list was published in 1886, I 

 caught a male of this species at St. Favin's Head, near here, and 

 almost directly after I saw two which Mr. Theobald had taken near 

 Buxton. 



T. rujina, Mg. : this and an allied species were common at 

 Inchnadamph, and I fancy T. rujina is not uncommon in the north.
