MEIGEN'S FIRST PAPER ON DIPTERA. 



Since the publication of my article in the October number, page 

 370-373, I have received Vol. Ill of Kertesz's Catalogus Dipterorum, 

 and I notice that he accepts all of the 1800 names that come within the 

 limits of this volume, five in number. I also have received the September 

 number of the Wiener Entomologische Zeitung, in which Dr. Bezzi reviews 

 Kertesz's third volume. He makes the remarkable admission that the 

 rules of the International Zoological Congress perhaps do not justify the 

 use of the 1800 names, but at the same time praises Kertesz for adopting 

 them. As the admission is fatal to the case built up by Hendel and Bezzi 

 (with the present co-operation of Kertesz), I deem it advisable to quote 

 his exact language (Wien. Ent. Zeit., XXVII, 252) : 



" In diesem Bande hat sich dsr Herr Verfasser streng an das 

 Prioritatsgesetz gehalten ; wir finden fiinf Neigensche Gattungen von 

 1800 wieder in Gebrauch gestellt, und zwar Potamida fiir Ephippiim, 

 Hermione fiir Oxycera, Eulalia fiir Odontomyia, Er'uma fiir Xylophagus 

 und Chrysozona fiir Haematopota. Aus demselben Grunde sind auch 

 Solva, Walker, fiir Stibuia {Xylomyia, Rond.), Pantophthahmis^ Thunb., 

 fiir Acanthotnera und R/iagio fiir Leptis gebrauclu 



"Ganz besonders hervorzuheben ist die richtige Nomenklatur, 

 welche, wenn auch nicht immer den neuen internationalen Regeln 

 entsprechend, jedenfalls mit den klassischen Grundsatzen der Wissen- 

 schaft iibereinstimmend ist." 



As I showed last month, it was Dr. Bezzi and Mr. Hendel together 

 who worked up the 1800 paper of Meigen ; we now have the feeble sug- 

 gestion of one of them that their proposed names, "even if not entirely in 

 agreement with the new International rules, are, at any rate, in harmony 

 with the classic principles of science." 



I surely need not pursue the subject further.

A CORRECTION. 

 On page 349 of this volume, the expanse of wings of Argyroploce 

 abietana, n. s., should have been given, 11-13 mm. and not 21-23 mm.
