C. B. Osten Sacken ; 



placed in the group „Stigma nunc", while the description, p. 276 has: 

 „stigmate fusco"! — The synonymy of these species in Zetterstedt 

 and Stäger I leave to others to unravel; there is some confnsion in 

 their nomenclature to which I have alluded in the Stett, E. Z. 1854. 

 E. cinerascens Walk. 1. c. is very probably a rather indifferently 

 characterized trivialis M. of the variety provided with a discal cell. 

 The passage in my Studies, II, p. 195, line 10 from top, beginning 

 with: „whose synonymy with ciliaris" etc. and ending with: „requires 

 contirniation", must be Struck out, as there is not the slightest doubt 

 about this synonymy at present. 



5. Tipula ocellaris Lin. 



In hunting up the references to Tipula annulata Lin. in the 

 dipterological literaturc (comp, above, § 3) I became aware that the 

 name of T. ocellaris Linne. Fauna Suec. 1751, has been, in various 

 ways, misapplied to other species than Linne's original one. 



Linne's description in the Fauna Suecica, as I find it reproduced 

 in Villers' edition (Lyon 17?S9, Vol. III, p. 362), runs as follows: 



„Ocellaris, alis albidis maculis ocellaribus nigricantibus 

 plurimis. 



Des er. Media. Alac expansae, albidae, duplici serie ocellorum 

 fuscorum, quorum margine exteriori adjacentes obscuriores. 



Hab. In Kuropa; in Bressia V." (Bressia, in french Bresse, is 

 a part of Burguudy; V. of course means Villers.) 



I omit the references, as unimportant, except one, the only one 

 which I also find in Linne, XII th edit. p. 973, 17 under Tipula 

 ocellaris (in the X th edit. this species is not mentioned): 



Gadd, Satag.87, which means (as I find in Hagen's Bibliotheca I, 

 p. 260): P. A. Gadd (1727 — 1797), Observationes physico-oeconomicae 

 in septentrionali praetura territorii superioris Satagundiae collectae. 

 Aboae, 1747, 4. p. 35, conf. Biblioth. Banks in the British Mus. I, 

 p. 114. This reference is not accessiblc to ine. 



There arc three European Tipulidae which, on aecount of the 

 ocellate spots on their wings can compete for the specific name 

 ocellaris Lin. One of them has been described by Linne himself 

 as Tipula (TrochobolaJ annulata, and is therefore hors tle cause. 

 Of the two others, Epiphragma pieta M. and Erioptera (Acyphona) 

 macidata M., it is the former which is nearest to Linne's description. 



As early as 1781 Schrank had speeimens which he identified 

 with T. ocellaris Lin. (Ins. Austr, p. 425, No. 856). Quite indepen- 

 dently of Schrank, Curtis in 1824 published a beautiful plate 

 representing what he quite correctlv considered as T. ocellaris L.
