THE ENTOMOLOGICAL CODE, a(S 
Ending of prefixes in 7, 0, or a, as albipunctata, albopunctata, and 
albapunctata. 
r or rr before h, as hemorhoidalis and hemorrhoidalis. 
61. In case of primary homonyms the later name shall be 
changed, no matter to what genus they are now referred. 
62. In case of secondary homonyms the earlier one shall retain 
the name, the later species to be renamed. This shall follow no 
matter which is first referred to the genus. 
Example.—A Ipha alba Smith 1854. 
Beta alba Jones 1847. 
In 1848 Beta alba is referred to the genus Delta, and 
in 1852 Alpha alba is also referred to Delta. Beta 
alba Jones must be renamed. 
63. In case a secondary homonym which has had its name 
changed on that ground, is referred out of that genus, its former 
name is to be restored; but if it is again referred to that genus, or 
another in which it is a homonym, the previous change of name 
again becomes effective. 
Example.—A pha alba Smith 1824 is referred to the genus Beta 
and is not preoceupied by the Beta alba Jones 1812, which has been 
referred to the genus Delta. But if now the Beta alba of Jones be 
re-transferred to Beta, then the alba of Smith will have to be re- 
named, or if it had been renamed before, while both species were in 
Beta, the name by which it was previously replaced comes again 
into use. 
64. If a species is described in, or referred to, a genus to which a 
species of the same name has at a previous time been referred, but 
does not now belong thereto, the later name shall not be changed.’ 
Example—A/pha alba Smith 1892. In 1860 the Beta alba of 
Jones was referred to Alpha, but later referred to Delta; the Alpha 
alba Smith is not to be changed. 
65. A specific name, even in synonomy, preoccupies the use of 
that name in the genus, provided the synonym is a valid name. 
66. Misspelled specific names cannot preoccupy other names, but 
an emended name and names suggested as substitutes will preoccupy 
in both the emended and original spelling. 
1Entomologists should refrain from duplicating combinations which have 
entered largely into recent literature, such as Phyllodromia germanica, Dory- 
phora decimlineata, Mytilaspis pomorum, ete.
