COMMON BUTTERFLIES OF THE PLAINS OF INDIA. 531 



has it too), when feeding in the mornings and evenings, from 

 flower to flower, sailing along with the wings held over the back at 

 about 45° to each other at intervals. It is to imitate these the 

 better, perhaps, that the females of the present species afiect a slower 

 rate of progression than their males. While the protected insects, 

 however, feed mostly, as said, in the mornings and evenings, 

 these others are not addicted to that practice but feed at odd 

 times throughout the day ; they are seen generally in the under- 

 wood and shady places looking for leaves whereon to deposit their 

 eggs. The cyrus form of the female is nowhere common in the 

 Bombay Presidency as far as is known, whereas both the other 

 forms are equally plentiful. It is probable, indeed, that the form 

 is nowhere very plentiful throughout the range compared to the 

 polytes form. The form imitating P. hector — romulus — is found only 

 in the area frequented by P. hector ; a very peculiar fact. Another 

 extraordinary thing is that where local forms of P. aristolochice 

 occur, there the pohites form is also modified in a more or less 

 similar way. Things go even further than that : in Celebes where 

 typical i^olytes males do not exist, being replaced by a constant 

 similar but aberrant race called P. iMhjtes alcinder, Oberth., the 

 female is onl}- of one type and that imitates a butterfly of the 

 P. hectm- group called P. j^olyphontes, Boisd., which is only found 

 in Celebes and some few neighbouring islands of the Gilolo group ; 

 and this although P. aristolochioi exists there. Why ? It is 

 difficult to even guess at an answer. 



P. pohjtes is found throughout British India, including the 

 Andamans and Nicobars ; extending to Siam and the Malayan 

 Subregion to Celebes ; China and Formosa. 



The food-plants of the larva are Zaoithoxylum Bhetsa, DC. ; 

 Glyscosmis 'penta'phylla, Correa ; Citrus medica, L. ; Citrus decwnana, 

 L. ; and others of the Rutacece. 



The figure 25a on Plate D2 has the fore wings much too red ; the 

 light parts should be grey or blue-grey. The figure of the male 

 is very good (fig. 25). 



84. Papilio clytia,i. — There are two forms : one something like a Euplceca 

 core, dark-brown with white bordering marks ; the other the same with 

 broad white streaks between the veins, imitating Danais limniace perhaps ; 

 and males and females of both are equally common.
