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, &c. 



Names taken from native languages, such as Indian, Malay, Phil- 

 ippine, &c, 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, o, u or y add a, us or um to the name. If it ends in a, then ia 

 is added to the name. If it ends in a consonant add ia, mm or ius 

 to the name. 



In latinizing personal names for use as specific names the usual 

 rule is to add i, if masculine, or se, if feminine; but in many cases 

 where the name ends in a vowel it is better to change that vowel to i 

 and add i or se. Often names ending in o should have i or se added 

 to the genitive of the name. 



Example. — An insect named in honor of Mrs. Slosson is slossonse, 

 one named for Mr. Smith is smitlii, 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 spainicus. 



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. 



Prefixes or suffixes of a generic name are useful in forming names 

 for segregates of a genus, as Ilybius, Ilybiosoma, Galeruca, Galeru- 

 cella, Dachne, Megalodkichne, Hypodachne, &c. 



In making names based on words having diacritic marks, such 

 marks'need not be retained, as Stalia, in honor of Stal. 



Names expressing diminution or resemblance are often helpful, 

 as Tettix, Tettigelfa, Climacia, Glimcucina. 



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
