RIJOPALOCERA MALA YANA. 



grow iiig iu grassy patches amongst cultivated fields." * Mr. Forsayeth also adds the following 

 iuterestiug particulars :—" The larva; appear invariably to attach themselves to the leaf 

 on which" they are feeding by a tine, almost invisible, web. On removing a larva from the 

 leaf the web is dragged away by the feet, and then is easily seen. I have also noticed that 

 they devour their exuvite, at least I never could find a cast skin in the cages in which I bred 

 the larvcB from early youth to maturity." f 



Dr. E. Bonavia found, whilst breeding this species at Etawah, in India, that the larv^ 

 were attacked l)y parasitic flies belonging to the Tachiniim; whose eggs thus deposited in the 

 caterpillar resulted in one chrysalis having succumbed in the struggle for existence with six 



larvie as internal parasites.'

This is a remarkable group, the distribution of which is focussed in the Indo-Malayan 

 region. These Papilios "mimic" other protected butterflies, principally species of the genus 



Eriplaa. 



Two species — according to present knowledge — are found in the Malay Peninsula ; a tlnrd, 

 I'.aiiiijma, has been recorded by Mr. Wallace || as common to Malacca, Sumatra, and Borneo, 

 but the first locality is probably incorrect, as the Malay Peninsula possesses a closely allied 

 form or species in the V. hutU'vi, Jans., here enumerated, and we have seen in other families 

 that these local forms or species are generally quite constant and peculiar to their restricted 

 habitats.
