is stränge. Instead of adding to the synonymy of punctata (Fauna, 

 II, p. 552) the obscure and misleading reference to „Meig., I.e. I, 

 p. 152, 65 (ocellaris). — ? Linne, F. Suec. (Tip. ocellaris)" , hc should 

 have simply stated that what Meigen saw in Fabricius's collection 

 was punctata, erroneously labelled ocellaris Lin. 



In Walker, Ins. Brit. Dipt. III, p. 288, the references to punctata 

 and picta are reproduced from Meigen and Schiner. Zetter stedt 

 X, 3817 follows Meigen in regard to punctata, but makes it worsc 

 by quoting ocellaris Schrank with a query and ocellaris Fabr., Syst. 

 Antl. 21», 27 also with a query! On the next page, in describing picta 

 it never oecurs to him that it is the true ocellaris Lin. Macquart, 

 S. ä ß. I, p. 96 about these two species merely refers to Meigen. 



It will not be amiss also to state that Seh in er (Fauna, 1. c.) 

 should have quoted punctata Schrank, Ins. Austr. 858 (1781) and 

 Meig., Klassif. p. 61 (1804), and only after them Meig., Syst, Beschr. 

 (1818). Meigen, in bis prineipal work, habitually omitted references 

 to Ins previous publication. and, in the present case Schiner, from 

 this cause, overlooked that Schrank was the authörity for punctata. 

 Schiner in Ins Catal. System. Dipt. Europae p. 19, again repeats: 

 Poecilostola punctata Meig. (syn. ocellaris Lin.), without any query ! 

 This has been copied by many other writers (for instance Nowicki, 

 1873; Kowarz, Adatok, 1883 etc.). Verrall (1886) and Kowarz 

 (Fliegen Böhmens, 1894) have it correetly punctata Schrank, but 

 Verrall should not have added as synonym: ocellaris Meigen, which 

 represents nothing (compare below). 



The synonymy of the different interpretatinns of ocellaris Lin. 

 aecording to my opinion, now Stands thus: 



1. Epiphragma ocellaris Linne. 



Tipula ocellaris Linne, Fauna Sueciea (1751); Schrank, Ins. 



Austr. 856 (1781); Lhnnobia ocellaris Curtis, Brit, Ent. 



50 (1824). 

 Tipula picta Fab., Ent. Syst. Suppl. p. 550 (1798); Lirnno- 



bia picta Meig.; Epiphragiiia picta Schin. [O.S.] 



2. Poecilostola punctata Schrank. 



Tipula punctata Schrank, Ins. Austr. 858; Lhnnobia punctata 

 Meig., Classif. and Syst. Beschr.; Poecilostola punctata 

 Schiner. 



NB. The Tipula ocellaris seen by Meigen (I, p. 122 

 and 152) in Fabricius's collection was merely a 

 wrongly labelled speeimen of P. punctata, and there- 

 fore must not be quoted ocellaris Meigen. because 

 this combination does not represent any scientific 

 coneept.
