NOMENCLATURE. 147 
points submitted to them for their opinion. It may be stated that in 
all cases the decisions of the committee were absolutely unanimous. 
A. Diprera. 
1. Heliodromia, Haliday, is the genus of which immaculata, 
Haliday, is the type, and Sciodromia, Haliday, is a synonym 
of Heliodromia. 
Hydrodromia, Macquart, is the generic name of bipunctata, 
Hal., and stagnalis, Hal. 
B. Leprporrera. 
2. Cydia, Hub., is the genus of which pomonella, L., is the type, 
consequently the generic name Carpocapsa, Treit., falls as a 
synonym. 
3. It seems scarcely credible that it could be necessary to submit 
such an absurd question but there is no doubt that such a 
case has arisen or so eminent a scientific entomologist as 
Dr. Karl Jordan would not have formulated the following :— 
“‘ X proposed a name for a supposed species closely allied 
to another species ; he does not know which of these species 
has been already named, and wishes his new name to be 
applied to the one which has no name. What is to be done 
with the name proposed by X ?”’ 
Of course the committee unanimously deposed such a name. 
“A valid name can only be applied to a definite conception ; 
. . X has formed no conception as to the particular 
species to which the new name is to be applied—there is, 
therefore, no species nor type to which the new name can be 
applied.” 
4. The name podalirius, L., should stand as the species name, and 
not sinon, Poda, as suggested by Verity and others. 
5. The form typical of the species podalirius was that figured by 
Rosel, ‘‘ Papil. Diurn.,” Cl. IL, plt. 2, fig. 3 and 4, as cited 
by Linné. 
. 8. These three questions were similar. Are we to consider 
particular forms of P. rapae, P. napi, and P. brassicae re- 
spectively as typical of the species described by Linné ? 
The general answer to all three questions is that we are 
not to do so, but that there is every evidence that these 
names being of generally distributed species were ‘‘ compre- 
hensive terms,” and hence “ the First Reviser was at liberty 
to restrict the name to whieh form he preferred.’’ In the 
case of napt the opinion points out that Esper was the first 
reviser when he proposed the name for the summer form, 
napaede. 
9. In the genus Anthocharis the name belia, L., must be substituted 
for the insect modern usage has called euphaeno, L. 
10. We must substitute crameri, Btlr., for belia, Cram., as the older 
name was mis-applied. 
11. Re rhamni. See replies to 6. 7. 8. 
12. States that cleopatra, L., is undoubtedly the name for the North 
African form which is typical of the species, hence, ‘‘if neces-
