system. Hence, if subsequent authors should give to some genera 

 the names used by Geoffroy, they must mention as the name of the 

 author not Geoffroy's but that of the author, who first added to such 

 a generic name, a Latin or Greek name of the species, for, ' perfecte 

 nominata est planta nomine generico et specifico instructa' (Linnaeus). 

 We may, however, acknowledge the merits of Geoffroy, by adding, as 

 it is said above, as a synonym, the name which is used by him. 



" II. If some existing genus must be divided into more genera, the 

 original name must be applied to that division which was considered by 

 the original author as the most typical. 



" If the genus, according to the first description, contains a single 

 species, or if the author has indicated a peculiar species as its type, 

 the application of the above-mentioned rule will not offer any difficulty. 

 If, on the contrary, several species are included in a genus, and none 

 of them has been indicated as the type, the decision is more difficult, 

 and every case must be judged by itself. In such a case many authors 

 seem to be inclined to consider as type of the genus the first species 

 which is found in the locality where the author lives, but it may be 

 doubted whether this view of the matter is in accordance with the 

 author's intention. 



" The conclusion at which the Committee has arrived is that, on 

 account of the above-mentioned reasons, this substitution of existing 

 and generally adopted names for those introduced in the ' Catalogus 

 Coleopterorum Europae,' by Dr. L. von Heyden, E. Reitter and 

 J. "Weise (ed. Ill, 1883), and in M. des Gozis 'Becherche de l'espece 

 typique de quelques anciens genres ' (1886), cannot be justified, and 

 will cause only needless confusion in the entomological literature.

A long discussion followed the reading of this report, but the 

 method, introduced by the authors of the 3rd edition of the " Catalogus 

 Coleopterorum Europse," and by Mr. des Grozis, did not find a single 

 defender among the members present. Some of them were of opinion 

 that the evil ought to be resisted not only with respect to the generic, 

 but also to the specific names. Others held that we ought not to 

 confine ourselves to Entomology only, but that Zoology in general is 

 interested in the matter. 



Einally, the meeting approved unanimously the conclusions of 

 the report, which may thus be considered as expressing the opinion of
