The above table is arranged merely for reference, using easily ascertain- 

 ed characters only ; natural affinity has no part in it. If the genus Papilio 

 as constituted by the species here mentioned were to be grouped accord- 

 ing to the relationship of its members, these groups would be as under — 



Group I : — 

 Omithoptera minos 

 Papilio hector 



. , aristolochice 

 „ pandiyanus 

 with the larval characters as already given ; the pupee of the last two 

 abnormal in having abdominal expansions, of minos quite normal. The 

 clasper-character further distinguishes the first from the other two in the 

 imago state. The food-plant of all three is Aristolochia of several species of 

 the Family Aristolochiacees. 



Group II : — 

 Papio clytia 

 already mentioned : with the larva shaped as in the foregoing, the abnor- 

 mal, stick-like pupa and the food-plants Litsea Alseodaphne, Cinnamomtim, 

 of the Family Laurincs. 



Group III : — 

 Papilio demoleus 

 „ daksha 

 „ polymnestor 

 „ polytes 

 „ dravidarum 

 with the larvse and pupse quite normal : the young caterpillars resembling 

 bird-droppings in colouration and pattern, quite naked ; in the mature 

 stage the colour is a rich green crossed by sullied white bands. The food- 

 plants are all of the Family Rutacecs. 



Group IV : — 

 Papilio tamilana 

 „ buddha 

 „ erino 

 with larvte and pupte resembling the last group but nearly without mark- 

 ings, the latter narrower than those in that group. The food-plants are 

 rutaceous. 



Group V : — 

 Papilio eurypylus 

 „ sarpedon 

 „ nomius. 

 „ antiphates 

 ,, agamemnon
