Genus LEPTOCIRCTJS. 



Making, in all, twenty distinct groups of Malayan 

 Papilionidae. 



The first section of the genus Papilio (A) comprises 

 insects which, though differing considerably in struc- 

 ture, having much general resemblance. They all have 

 a weak, low flight, frequent the most luxuriant forest- 

 districts, seem to love the shade, and are the objects 

 of mimicry by other Papilios. 



Section B consists of weak-bodied, large-winged in- 

 sects, with an irregular wavering flight, and which, 

 when resting on foliage, often expand the wings, which 

 the species of the other sections rarely or never do. 

 They are the most conspicuous and striking of eastern 

 Butterflies. 



Section C consists of much weaker and slower-flying 

 insects, often resembling in their flight, as well as in 

 their colours, species of Danaida3.
