of the orange tribe. The chrysalis is much the same as in P. eritho- 

 nius; the points on the head are more produced, and it has, as it were, 

 elbows about the middle. In both of these species the chrysalides 

 are very variable in colour. I have reared green, black or dark 

 ashy, grey mottled with brown, green and grey, and pale pink ones. 

 When disturbed the chrysalis has the property of moving the body 

 with a jerk and emitting a faint creaking sound. 



114- Papilio aristolochice, Fabricius. The ground-colour of this 

 butterfly is very deep blue almost approaching black in its depth in 

 fresh specimens. In faded specimens the colour is browner. On 

 the hindwing there is a white patch surrounded by a few pale red 

 marks. Underneath, the colour of the forewing is the same as above, 

 of a dark blue or brown approaching black in its depth; but the 

 hindwing has a white patch in the centre which is surrounded by 

 brilliant scarlet spots. It can be distinguished from its mimic, the 

 female of P. polyte*, at once by its having a scarlet and black body 

 and head. The hindwing is also adorned by a spatulate tail. It 

 appears that this butterfly is naturally protected by an odour which 

 pervades its body, and is therefore mimicked by other butterflies. 

 The shape of the wings is peculiarly elegant, the forewing being long 

 and narrow, and the hindwing being long and narrow in the opposite 

 direction. It has a peculiar fluttering- kind of flight. 



115. Papilio hector, Linnaeus. This grand butterfly resembles 

 the preceding one in general shape and manner of flight, but it is 

 altogether larger and more brilliantly coloured. The ground-colour 

 is of a deeper tone of blue even than in P. aristolochice. The fore- 

 wing is adorned with two conspicuous white bars arranged as in the 

 third form of the female of P. polytes, its mimic. The hindwing 

 has two rows of brilliant scarlet spots or half moons following the 

 bend of the margin of the wing, and each hindwing has a rather 

 narrow tail in addition. The wings are further bordered by a very 

 narrow white band. The underside is just the same as the upper. 

 The appearance of this butterfly is very rich and striking. 



116. Papilio nomius, Esper, This is a very delicate fragile-looking 

 " swallow-tail," of extremely elegant appearance. The ground- 

 colour is pale green — " eau de nil" I suppose it would be called by 

 ladies. The forewing is bordered with black on the outer margin,.
