164 C. R. Osten Sacken: 



females of which he had specimens, for males and the dichoptic Q of 

 Liponeura, which was also among his specimens, for the Q of his 

 Bleph. d". If Loew had noticed this disagreement between Macquart 

 and Schiner, he would not have had any reason to say (Revis. p. 60, 

 1877): „Whether Schiner was led into the confusion of both genera 

 by a similar confusion as Macquart, or for some other reason, I 

 am unable to decide (kann ich nicht beurtheilen)." 



In consequence of this mistake Loew's synonymy of the two 

 genera and species on p. 87 and 88 (Revis. etc. 1877) must be re- 

 placed as foUows: 



Blepharocera Macq. (1843). i) 

 Syn. Asthenia Westw. 1842. BlephaHcera Macq. Aniended 

 in Blepharocera by Loew 1862. 

 1. fasciata Westw. (2). Loew, Bnll. Soc. Ent. Ital. 1869. 



Syn. cf. The male has not been described yet, although it has 

 been found in several localities: for instance by Mik, 

 near Görtz, in 1864. 



Syn. Q. Asthenia fasciata Westw. Guerin, Mag. 1842, Q. 

 (Lw. 1877, p. 63, 1. 17 from bottom). 

 Blepharicera limhipennis Macq. Ann. S. E. Fr, 1843 

 (taken wrongly for a cf)\ 1844 (recognized as Q). 

 Blepharicera fasciata cf. Schiner, Fauna II, p. 637 

 (1864) (wrongly taken for a male). 

 Liponeura Loew, Stett. Z. 1844. 

 1. cinerascens Loew, Bull. Soc. Ent. Ital. 1869, p. 97, c/2. 

 Syn. cf. Blepharicera limhiiyennis Macq. 1844. cf- 



NB. This is the Lip. ein. cf, which Macquart 1844 

 took for the male of his Bleph. limbip. (comp, above). 

 Syn. Q. Liponeura cinerascens Lw. 1844, p. 118 (erroneously 

 taken for a cf). 

 Blepharicera fasciata 2 Schin. Faunall, p. 637 (1864). 

 NB. In this case Schiner mistook a Q Liponeura., 

 for the Q. of his Bleph. fasc. c/"; the latter, in reality, 

 was a female (comp, above), 



The historical account of the Blepharoceridae by Loew 

 (1877) is correct as far as p. 60 at top, where, instead of: „sondern 

 auf dasjenige von Lip. ein.", must be put: „sondern auf Bleph. 

 fasc. Q.". And farther on, line 13 and the rest, must be read: 



^) I do not know why Loew, Schi. Z. 1877, p. 87 puts it: Ble- 

 pharocera Lw. 1858?
