3o6 APPENDIX A. 



Kurz bemerkc ich hier, dass ich, im Interesse einer vollig stabilen 

 Nomenclatur, gegen jede Umanderung der Artnamen, aus welchem 

 Grunde es immer sein moge, bin. Selbst die Aenderung der 

 Endungen wegen des (zuweilen recht fraglichen) Geschlechts der 

 Gattungsnamen halte ich fur umgebracht, ganz abgesehen davon, 

 dass viele Arten haufig die Gattungen wechseln. Ich halte es fur 

 richtiger, Artnamen niemals als Adjectiva, auch wenn sie solchen 

 entnommen sind, sondern fUr zu Substantiven gewordene Nomina 

 propria (Beinamen, Vornamen) anzusehen, weshalb ich bedaure, 

 dass dieselben jetzt fast iiberall mit kleinem Anfangsbuchstaben 

 geschrieben werden."

" As to this point I would be willing to follow custom, which we 

 have been following in using iidae and iinae. If now it is proposed 

 to write iadae and ianae I should not object. But entomological 

 latinity is open to general suspicion, and perhaps this question is 

 not vital for the moment. Since the question is raised, I would 

 agree with Lord Walsingham* that it would be better that iadae 

 and ianae were used."

" iadae, ianae to be adopted." 



QUESTION VII. 



" By what process is the type of a heterotypical genus 

 to be ascertained ? 



a. What is the type of Phalaena, L. ? 



b. What is the type of Tortrix, L. } 



c. What is the type of Tinea, L. } 



d. What is the type oi Ahicita, L. ? 



ShoM^ how^ the result is arrived at in each instance, and 

 discuss the value of the names Phalaena, L. and Tortrix, 

 L., giving the reasons for your conclusions, and stating on 

 what jDublished or unpublished rules you rely ?"
