24 THE ENTOMOLOGICAL CODE, 
In some groups it is customary to have uniform terminations or a 
common root, thus facilitating reference. Examples are tortricid 
specific names ending in ana, and tineid names ending in ella, &e. 
Names taken from native languages, such as Indian, Malay, Phil- 
ippine, &e., are often found useful when latinized for names of 
genera and species. 
Personal names should be used sparingly, especially for genera. 
The British Association in 1865 well said: ‘The handing down the 
name of a naturalist by a genus has always been considered as the 
highest honor that could be given, and should never be bestowed 
lightly.” 
To form generic names from personal names, if the name ends in 
e,i,0, wor y add a, us or wm to the name. If it ends in a, then ia 
is added to the name. If it ends in a consonant add ia, ium or ius 
to the name. 
In latinizing personal names for use as specific names the usual 
rule is to add 7, if masculine, or &, if feminine; but in many eases 
where the name ends in a vowel it is better to change that vowel to 7 
and add i or «@. Often names ending in 0 should have 7 or # added 
to the genitive of the name. 
Example.—An insect named in honor of Mrs. Slosson is slossone, 
one named for Mr. Smith is sm7thi, one for Latreille is latreillii, and 
one for Antonio is antonini. 
A specific name based on that of a country should take its root 
from the Latin name of that country, if there is one. Thus an 
insect from Spain should be called hispanus or hispanicus, not 
spainus nor spaimicus. 
Two names in the same genus should not be based on the same 
Latin root. Thus hispanus and hispanicus in the same genus are 
objectionable. ss 
Prefixes or suffixes of a generic name are useful in forming names 
for segregates of a genus, as Ilybius, Ilybiosoma, Galeruca, Galeru- 
cella, Dachne, Megalodachne, Hypodachne, &e. 
In making names based on words having diacritie marks, such 
marks need not be retained, as Stalia, in honor of Stal. 
Names expressing diminution or resemblance are often helpful, 
as Tettix, Tettigella, Climacia, Climacina. 
In general it is not advisable to fix genotypes for genera with 
which the writer is unfamiliar. 
In subdividing a genus it is well to have the new genera agree in
