Ix 
and duly latinized in termination, as a proper name, write it with 
a capital letier, and treat it as unalterable. His collaborateur 
Wocke, however, does not agree with him, and therefore he does 
not fully carry out his views in this catalogue. 
3. The first describer of a species should have his name 
attached to it, even though it be removed to another genus. 
He protests, like Dr. Thorell, against the practice of botanists 
and of many American zoologists in this respect. 
4. Museum and catalogue names, without any recognizable 
descriptions, are void. 
5. Every species should absolutely preserve the name under 
which it has been first described, in accordance with the Linnean 
nomenclature. 
6. The same specific name may be employed in genera suffi- 
ciently remote from each other. 
7. A description founded on two or more species can only in 
exceptional cases be applied to either of them. 
8. Species described from the larve or pup only can not be 
retained should the perfect insect differ much from known 
species. 
Gemminger and Harold, whose great Catalogue of Coleoptera 
has been suspended owing to the Franco-Prussian war, but will it 
is hoped shortly be resumed, carry out the law of priority with 
sreat rigour; adopting the oldest name, however bad the descrip- 
tion may be, and although the identification is only possible by 
reference to the type specimen. But they do not admit the 
validity of any descriptions in fugitive papers or price catalogues. 
They ave purists in orthography, taking exactly the opposite view 
to the German Lepidopterist cataloguers, and unmercifully alter 
all names which they conceive to exhibit unclassical construction 
or erroneous orthography. 
One of the most important, if not the most important, of the 
entomological works of the year 1871 is, undoubtedly, Mr. W. F. 
Kirby’s ‘Synonymie Catalogue of Diurnal Lepidoptera;’ a 
volume of 690 pages on the general plan of Gemminger and 
Harold’s ‘Catalogue of Coleoptera.’ It is issued as a complete 
work, containing all, or very nearly all, the species and varieties 
of butterflies described down to the date of publication, with very 
full synonymy accompanied by dates, and with a column of 
localities. There is no enumeration of the species either in the
