Glare Island Survey — Dipterd. 25 3 



Becker, &c, but have also adopted the names recently resuscitated by Hendel 

 and other authors from the long-lost paper of Meigen's entitled " Nouvelle 

 classification des mouches a. deux ailes (Diptera L.)." This paper has given 

 rise to a good deal of discussion and controversy ; but as the International 

 Commission on Zoological Nomenclature has decided (Opinion 28, October 

 1910) that the generic names there used must take precedence (when found 

 valid) over those used in Meigen's later works, I have decided to use such 

 names without question, following Hendel's opinion (Verhandl. der k. k. 

 zool.-bot. Gesellschaft in Wien, 1908, pp. 43-69) as regards validity or 

 otherwise. In pursuing such a course I fear many portions of the list possess 

 an unfamiliar appearance ; but to obviate difficulties I have inserted within 

 parentheses the names used in Verrall's List in each case where there is an 

 alteration. 



To save space the following contractions are used: — CI., Clare Island ; 

 M., Mainland; (EL), J. N. Halbert; (M.), Claude Morley ; (J.), Eev. W. F. 

 Johnson ; and (G-.), Percy H. Grimshaw. 



LIST OF SPECIES. 

 ORTHORRAPHA NEMATOCERA. 



Family Lycoriidae (Sciaridae). 



Lycoria (Sciara) flavipes Mg. — M. : Louisburgh, one $ (H.) ; Brackloon 

 Wood, one $ and one 2 (G.). — A woodland species, distinguished by 

 its large size, slender build, and light colour.

[Besides the above, over thirty specimens of this difficult genus were 

 taken, two on Clare Island and the rest on various parts of the adjacent 

 mainland. Several species are represented ; but I have not succeeded in 

 identifying any of them.]
