THE ENTOMOLOGICAL CODE, ita 
45. A specific name, if a Latin adjective, should agree in gender 
with the generic name, even when published in connection with a 
subgeneric name of different gender. 
46. Arbitrary specific names are not to be changed to agree in 
gender with the generic name. 
Example.—Cossus ore Str. is not to be changed to Cossus orca, 
orcus, or orcidis. 
47. A specific name given to any part or stage (except egg) of an 
insect, or to the cast or imprint of a fossil insect, is valid if otherwise 
available. 
48. A specific name based wholly on a cocoon, case, gall, leaf- 
mine, or other work of an insect is valid, if otherwise available, only 
until the insect itself is described, when that name and authority 
replaces the one based on the work. 
49. A specific name of an insect based wholly on characters of 
internal anatomy, on habits, or on anything other than external 
characters, or invaginated parts of the exoskeleton, is invalid. 
50. Rules applicable to specific names apply also to names of lower 
rank except as provided in section 37 and certain of the following 
ones. 
51. A subspecific, or varietal, name is a trinomial. 
52. One of the subspecific or varietal names shall be a repetition 
of the specific name and have the same type. The name of the 
typical variety is usually omitted. 
Example.—Papilio glaucus glaucus Linn (usually written Papilio 
glaucus L.). 
Papilio glaucus turnus Linn. 
53. The name of a race is a quadrinomial, and is usually given to 
a local form. 
Example.—Papilio glaucus turnus mexicanus Linn. 
54. A misidentification shall not be perpetuated as a valid species. 
Example.—Fitch, under the genus G!canthus, treats and describes 
a species (fasciatus) which he considers as being the Gryllus fasciatus 
of De Geer. It is now known that the insect before Fitch was not 
De Geer’s species. Thus the name (canthus fasciatus cannot hold 
for the species treated by Fitch, as it was a misidentification, not the 
proposal of a new species.
